What Is Shurlockr Ransomware?

ShurLOckr Ransomware

The ShurLOckr ransomware is a malware that is like other ransomware malware, but it targets cloud-based platforms as its distribution platform. This means that the ShurLOckr ransomware can spread to a wide range of people in the shortest amount of time.

ShurLOckr ransomware was discovered sometime in 2018 by Bitglass and Cylance. It’s a ransomware strain that was developed from the Godjue ransomware and is being offered as a Ransomware-as-a-service (RaaS) on the dark web. The ShurLOckr ransomware was discovered after it bypassed the security screening of Google Drive and Microsoft Office 365.

According to researchers, the ShurLOckr ransomware can bypass a cloud platform’s virus security scan and enter the cloud. Once ShurLOckr ransomware is in the cloud, it can be shared and distributed to any global user who has access to the cloud platform. Once opened, it can infect a company’s network even if they have strong security.

ShurLOckr Ransomware

A Guide to Understanding the Shurlockr Ransomware and Endpoint Protection

When it comes to cybersecurity threats, data theft and Denial-of-Service (DoS) attacks are ranked on top of the list. These threats can do considerable damage to a company or organization and can take a long time to fix after an attack. But ransomware, especially the ShurLOckr ransomware, is much more dangerous.

Characteristics of Ransomware

Being hit by the ShurLOckr ransomware is a cause for alarm and should be dealt with immediately. This is especially true for companies that hold sensitive data in their databases that can be used for blackmail or fraud.

But to prepare for a ransomware threat, it’s important to know the characteristics of ransomware:

File encryption: The first characteristic of malware is its ability to encrypt files and data. Once the ransomware is released on a computer, it scans for files that can be encrypted. It usually hunts for pictures (.jpeg, .png, .tiff, etc.) documents (.docx, .xlsx, .rtf, etc), video (.mp4., .wmv, .avi, etc.), and other personal files.

Sometimes, the malware can take over the entire computer, locking users out of their computers until the decryption code is given to the ransomware. The ShurLOckr ransomware is known only to encrypt files and does not lock users out of their computer or device.

High-level encryption algorithm: Almost all ransomware has high-level encryption. This is to ensure that brute-force decryption cannot be done. This is true with the ShurLOckr ransomware as well.

Ransomware uses a sophisticated encryption algorithm that can be opened with the decryption key. Some ransomware uses a custom-built encryption algorithm, making it hard to break. While many variants of ransomware receive a unique encryption key from the hacker’s online server for every encryption. And the uniqueness of the encryption key makes it hard to crack through brute-force.

Some decryption tools online try to crack the strong encryption of ransomware, but many have limitations and the success rates are low.

Demand letter: Because ransomware is a malware that holds files hostage for ransom, it will always have a ransom letter asking for a large sum of money. As a strain of another ransomware, the ShurLOckr ransomware may also have this.

Most demand letters of ransomware have the same content, especially if they are variants from the same family of ransomware. They ask for a large sum of money, offers to decrypt one file as proof, and require victims to contact the hackers after within a couple of days. Failure to follow the instructions could lead to higher pay demands.

Bitcoin payment: Another trademark characteristic of ransomware is the demand for payment through Bitcoin instead of cash. Hackers prefer being paid in bitcoin or another cryptocurrency because it cannot be traced to a single location. There has been no reported amount for the ShurLockr ransomware so far.

Other than cryptocurrency being highly untraceable, ransomware hackers also prefer to use cryptocurrency because it does not leak any identification and is not regulated by any bank or government.

Other malware payloads: Though not all ransomware has this, the dangerous ones do. Ransomware on its own doesn’t harm your system or steal your data; it just encrypts it and asks for money. Fortunately, the ShurLOckr ransomware doesn’t have any reports of dangerous malware payloads.

But when it has another malware payload attached to it, this malware could end up breaking your system or stealing your data. Sometimes, hackers add a malware that tracks your keystrokes to try and steal your passwords.

Ransomware used in whale phishing attacks could have a malware payload that steals a specific kind of data which can be used for fraud and blackmail.

How Does Ransomware-as-a-Service (Raas) Work?

Because ransomware offers a huge potential for financial gain, many hackers and cybercriminals want to use this type of malware. Ransomware developers saw the market for ransomware and decided to offer it as a service, thus came the “Ransomware-as-a-Service” (RaaS). The ShurLOckr ransomware is offered as a RaaS.

The business model of Ransomware-as-a-Service depends on the malware developers. Some RaaS has a similar business model as Software-as-a-service (SaaS) where the malware developers offer hackers and clients a software kit to customize the malware’s features depending on their preferences. The developers maintain the ransomware and get a cut of the profit when someone pays for the data back.

Another business model is developers sell the kit for a price and leave the buyer to run the program themselves or customize it as they please.

Ransomware has become a profitable software not only for the developers but also for the users. More and more victims of ransomware are paying for the data back, even organizations and high-profile personalities are willing to pay for their data.

In 2013, the actors behind the Cryptolocker ransomware attack garnered an estimated 3 million dollars’ worth of ransom money.

RaaS has a growing market in the dark web. And in a few years, the market for ransomware-as-a-service would hit over a billion dollars.

Why Ransomware on Cloud Apps Can Be Dangerous?

Ransomware in and on itself is dangerous. But when it enters the cloud platform, it can cause damage at a much larger scale. The ShurLOckr ransomware made this threat possible.

Researchers that discovered the ShurLOckr ransomware said that the ransomware can only be detected by 7% of antivirus engines available in the market. And that the cybersecurity offered by cloud service providers are hardly enough to keep the ShurLOckr ransomware out of the cloud servers.

This characteristic of the ShurLOckr ransomware can be exploited in the development of future ransomware viruses and can be weaponized. If it managed to bypass the cloud’s security screening, nobody can say what any future malware will be able to do in the cloud.

In a future worst-case scenario, ransomware could activate in the cloud, infecting the server and encrypting all the data stored in the cloud server, including the company’s backup files.

Why You Need Endpoint Security?

With the dangers packed in ransomware, prevention is much better than a cure. That’s why cybersecurity experts advise companies to secure their networks with endpoint security tools and systems.

Endpoint security is perhaps the most efficient ransomware preventive measure available. Since ransomware must first be in your system before entering your cloud platform, there must be no vulnerable opening in your network that cybercriminals can use as an entry point.

Endpoint security is a cybersecurity measure that strengthens the security of your network’s endpoints. These endpoints could be your employee’s workstation PC, an employee accessible server, a company USB device, and even your employee’s smartphone connected to the company network.

With endpoint protection, each of these endpoint devices must have a certain level of security before they are granted access to the company network.

How Does Endpoint Security Work?

Endpoint security is a simple but efficient cybersecurity technique that prevents malware from entering your network. IT professionals use several software and tools to ensure that each endpoint is compliant with the cybersecurity requirements before they are given access to the network. With an endpoint security

In endpoint security, the device user or owner is responsible for keeping their device’s cybersecurity up-to-date. This reduces the pressure on IT professionals to ensure that each device is secure, which creates a vulnerability when IT officers fail to check one device.

Endpoint protection also gives IT officers the power to monitor activities in the endpoint devices and keep track of the files and documents stored in them.

With global partnerships and bring your own device (BYOD) policies being implemented by many companies today, traditional cybersecurity techniques (network perimeter, IDS, Firewalls, etc.) can no longer protect the company network from foreign devices. Endpoint security and endpoint protection don’t have this limitation.

Accessing the company network from an insecure device creates a vulnerability and accessway into the network. These accessways can easily bring the ShurLOckr ransomware to the doorstep of your cloud storage.

Tools for Endpoint Security

The ability of endpoint protection to prevent malware like the ShurLOckr ransomware from entering your company network lies in the cybersecurity tools used for endpoint security. Below are some tools packaged in an endpoint security service:

Spam and email protector: Many ransomware, including the ShurLOckr ransomware, enters a private network through spam or fake email. That’s why many endpoint security providers offer spam and email protector in their packages.

Many email providers also have spam blockers built into the system to prevent spam from entering your inbox. However, this is not enough as fake emails could still bypass spam and email protectors.

Antivirus software: So far, the best prevention against ransomware is to have updated antivirus software installed on your endpoint devices. Updated antivirus software can easily detect malware signatures and block them from infecting devices.; this includes some ransomware and many other malware types.

However, no antivirus software is perfect, and if an unfamiliar malware manages to infect your device, the antivirus software is often deactivated without your knowledge. Some next-generation malware also behaved differently from old malware, making it difficult for the antivirus to catch them.

Web-protection software: Another entry point for ransomware and other malware is through the web. Malicious links and web downloads could inject malware into your device without your antivirus software detecting it.

Once infected, the malware would automatically attack your antivirus and deactivate it so that it can’t block the malware from spreading. SQL injections are the most common type of web hacking technique.

Antispyware: When hackers are trying to target a specific organization or person, the first thing they do is reconnaissance. They try and learn about the target and see what vulnerabilities they can exploit to enter the private network. And they do this through spyware.

Spyware is a malware that transmits information and data back to its host to give cybercriminal a better picture of their target and their behaviors and responses on their devices. Antispyware prevents this regularly scanning, monitoring, and eliminating spyware from your devices.

Next-generation antivirus and firewall software: Unlike traditional antivirus software and firewalls, next-generation antiviruses and firewalls don’t just look at signatures but as well as events and tools, techniques, and processes (TTP) used by cyberattackers.

Next-generation anti-virus and firewall offer better protection against new kinds of malware and conducts some form of malware forensics to learn an unfamiliar malware’s behavior. These kinds of software use a sandbox environment to check suspicious files and processes to see if the file is a threat to the system or not.

VPN: Lastly, endpoint protection service providers offer VPN services to ensure that the connection of one endpoint to another node in the network is secure.

VPN creates a secure and encrypted connection between the endpoint and network node to prevent a third-party from spying on the connection and gain data on their target. VPNs also encrypt files in transit so that cyberattackers cannot read an intercepted file.

Conclusion: The ShurLOckr ransomware is just the beginning of a new kind of ransomware. As technology further develops and new systems become available to hackers, it will not be long before we see the characteristics of the ShurLOckr ransomware to bypass security scans weaponized on a much more dangerous malware.

With this threat looming on many businesses and organizations, they need to take preventive measures now with endpoint security and protection services and be prepared for any malware attack possible.

What Is Endpoint Security

What Is Endpoint Security? and Why Is It Crucial Today?

What is Endpoint Security

Endpoint Security, Endpoint Protection refers to the approach of protecting a business network when accessed by remote devices like smartphones, laptops, tablets or other wireless devices. It includes monitoring status, software, and activities. The endpoint protection software is installed on all network servers and on all endpoint devices.

With the proliferation of mobile devices like laptops, smartphones, tablets, notebooks etc., there has been a sharp increase in the number of devices being lost or stolen as well. These incidents potentially translate as huge loss of sensitive data for enterprises which allow their employees to bring in these mobile devices (enterprise-provided or otherwise) into their enterprise.

About Endpoint Security

To solve this problem, enterprises have to secure the enterprise data available on these mobile devices of their employees in such a way that even if the device falls into the wrong hands, the data should stay protected. This process of securing enterprise endpoints is known as endpoint security.

Apart from this it also helps enterprises successfully prevent any misuse of their data which they’ve made available on the employee’s mobile devices. (Example: a disgruntled employee trying to cause nuisance to the enterprise or someone who may be a friend of the employee trying to misuse the enterprise data available on the device).

Endpoint Security Definition

Endpoint Security is often confused with a number of other network security tools like antivirus, firewall, and even network security. In this page, we list some of the differences between endpoint security (or) endpoint protection and the network against various evolving security threats of today.

Why Is It Called ‘Endpoint’ Security?

As you can realize, every device which can connect to a network poses a considerable danger. And as these devices are placed outside of the corporate firewall on the edge of the network using which individuals have to connect to the central network, they are called as endpoints. Meaning endpoints of that network.

As already stated endpoint can be any mobile device ranging from laptops to the notebooks of today, which can be connected to a network. And the strategy you employ in security these endpoints is known as ‘endpoint security’.

Endpoint Security Is Not The Same As Antivirus

Although the objective of endpoint security solutions is the same – secure devices – there is a considerable difference between endpoint security and antivirus. Antivirus is about protecting PC(s), – single or many depending upon the type of antivirus being deployed – whereas endpoint security covers the entire picture. It’s about securing every aspect of the network.

Endpoint security usually includes ‘provisions for application whitelisting, network access control, endpoint detection and response’, things which are usually not available in antivirus packages. It can also be said that antivirus packages are simpler forms of endpoint security.

Endpoint Security Is Different For Consumers and Enterprises

Endpoint security solutions can be broadly classified into 2 different types. One for the consumers and the other for enterprises. The major difference between the two is that there’s no centralized management and administration for consumers, whereas, for enterprises, centralized management is necessary. This central administration (or server) streamlines the configuration or installation of endpoint security software on individual endpoint devices and performance logs and other alerts are sent to the central administration server for evaluation and analysis.

What Do These Endpoint Security Solutions Typically Contain?

While there’s certainly no limit to what endpoint security can contain – and this list is only going to expand in the future – there are some applications which are core to any endpoint security solution. (Because, well, securing a network is altogether a different ball game from securing a computer).

Some of these applications are firewalls, antivirus tools, internet security tools, mobile device management tools, encryption, intrusion detection tools, mobile security solutions etc, to name a few.

Traditional Vs Modern Endpoint Security

This is a no-brainer. Yet something which needs to be pointed out. Because enterprises are often reluctant to changes. Even if it is for their own good. But endpoint security is one area where enterprises have no choice but to adopt the modern endpoint security. Because they are much more than just an anti-malware tool which can go a long way in securing your network against various evolving security threats of today.

Difference between Endpoint Security and Antivirus

Antivirus is one of the components of endpoint security. Whereas endpoint security is a much broader concept including not just antivirus but many security tools (like Firewall, HIPS system, White Listing tools, Patching and Logging/Monitoring tools etc.,) for safeguarding the various endpoints of the enterprise (and the enterprise itself against these endpoints) and from different types of security threats.

More precisely, endpoints security employs a server/client model for protecting the various endpoints of the enterprise. The server would have a master instant of the security program and the clients (endpoints) would have agents installed within them. These agents would communicate with the server the respective devices’ activities like the devices’ health, user authentication/authorization etc., and thus keep the endpoints secure.

Whereas antivirus is usually a single program responsible for scanning, detecting and removing viruses, malware, adware, spyware, ransomware and other such malware. Simply put, antivirus is a one-stop shop for securing your home networks, and endpoint security is suitable for securing enterprises, which are larger and much more complex to handle.

Difference between Endpoint Security and Network Security

Endpoint security is about securing your enterprise endpoints (mobile devices like laptops, smartphones and more) – and, of course, the enterprise against the dangers posed by these endpoints as well – whereas network security is about taking security measures for protecting your entire network (the whole IT infrastructure) against various security threats.

The main difference between endpoint security and network security is that in the case of former, the focus in on securing endpoints, and in the case of latter, the focus is on securing the network. Both types of security are important. Ideally, it’s best to start from securing the endpoints and building out. You wouldn’t leave the doors to your home open, just because there’s a security guard out there, would you? In the same sense, both are important and should be given equal importance, starting from the endpoints and slowly building out.

In very simple terms, your network would be secure only if your endpoints are secured first. This you should make note of before starting to look for endpoint security and network security products.

Difference between Endpoint Security and Firewall

Firewalls are responsible for filtering the traffic flowing into and going out of your network based on ‘a set of security rules’. Like, for example, restricting traffic flowing into the network from a particular potentially dangerous website. Whereas endpoint security concerns itself not just with network filtering but performs many other tasks like patching, logging, and monitoring etc., for safeguarding the endpoints.

Both antivirus and firewall are crucial elements of endpoint security. Their objective remains the same, though the model adopted (client/server model) and the number of computers they protect differ. And within the endpoint security model, operating with other security tools, they become even more efficient.

Difference between Endpoint Security and Endpoint Protection

Both are pretty much the same. Their primary objective is the same – to safeguard the endpoints as well as the enterprise against the dangers they pose. But there is a subtle difference. Endpoint security usually refers to an on-premise solution. Whereas Endpoint Protection refers to a cloud-based solution.

An on-premise solution is a solution which has to be installed on the network for deployment and a cloud-based solution is one which is available in the cloud and enterprises have to subscribe to it.

Windows 10 and Endpoint Security

Windows 10 although proclaimed to be the safest Windows OS is not without its flaws. Security experts have proved that the in-built security features of Windows like Windows Defender, Firewall etc., too are proving ineffective. Therefore enterprises making use of Windows 10 OS need endpoint security for safeguarding the various endpoints which connect to the network and for safeguarding the network itself.

Why Your Windows – Not Just Windows 10 – Needs Endpoint Security?

Inbuilt Windows Security is never going to be sufficient. Because the security attack vectors of today are just too many to be handled. Which means we no longer live in a world where e-mail attachments or web downloads are the only sources of malware infection. Simply put, your windows OS needs additional layers of protection in the form of antivirus for windows or, maybe, much more, depending on your requirements.

With this in mind, let’s take a look at how you can protect your Windows OS from various security threats:

  1. Keep Your Windows OS Up-to-Date: Today it’s Windows 10. Tomorrow there’ll be another new version. Whatever it may be, ensure your PC is updated to the latest version. This is probably the next best thing you can do apart from providing antivirus for windows. Because the latest update is usually the one which safeguards users against all known security vulnerabilities.
  2. Ensure Other Applications Are Up-to-Date: What’s inside of your Windows OS too matters. We mean other main programs and applications. Ensure all of them are updated and contain the latest security patches. Because it’s a well-known fact that hackers try to exploit popular software like Java, Adobe Flash, Adobe Acrobat etc.,
  3. Use Proactive Security Solution: Unfortunately traditional antivirus alone is not going to be enough. Especially when it comes to combating modern-day malware which employs sophisticated methods. Therefore to tackle the ever-changing cybersecurity threat landscape, users need proactive security solutions like internet security (for home users) and endpoint protection (for enterprises).
  4. Use Local Account Instead Of Microsoft Account: If you are using Windows 10, it’s best to avoid Microsoft account and instead opt for a Local account, as using Microsoft account means saving some of your personal details on the cloud, which is not such a wise thing to do. To opt for a local account, visit: Settings>Accounts>”Your info and select ‘Sign in with a local account instead”.
  5. Keep User Account Control Always Turned On: UAC (User Account Control) is a Windows security responsible for preventing unauthorized changes (initiated by applications, users, viruses or other forms of malware) to the operating system. It ensures changes are applied to the operating system only with the approval of the administrator. Therefore keep it turned ON always.
  6. Perform Regular Back-Ups: Prepare yourself with the ‘worst’ in mind when it comes to dealing with security threats. Therefore perform regular backups of your system (both online and offline) so that all your data is not lost in case your PC(s) are badly affected by security threats or encounter an irreparable hardware issue.
  7. Keep Your Browser Updated: Browsers are what we use to access the internet. Therefore security vulnerabilities in them mean entry path for security threats. Therefore, just as with OS and other applications, keep your web browser updated as well. Other security measures you can take: 1) opt for private browsing mode to prevent sensitive details from being stored 2) prevent or block pop-ups 3) configure web browser security settings to improve security etc.,
  8. Turn Off Location Tracking: If you are using Windows 10 or any other version which contains Location Tracking, it’s best to turn it Off or use it only when it is absolutely necessary. For example, if you want to know about the local weather or the various shops nearby etc., To turn off Location Tracking, go to Privacy >> Location >> click Change button and move the slider from On to Off.
  9. Use The Internet Wisely: All of the security measures listed here would become useless if you don’t exercise caution while online. Therefore ensure you don’t click on dangerous looking links, download malicious email attachments or other web downloads, avoid visiting suspicious looking websites and any other action which the current security practices deem as unwise.

Windows OS is probably the best and that is why it is hugely popular and has so much following – despite the security threats. And there’s nothing wrong with sticking to your favorite OS. Just ensure you beef it up with the right security products like Comodo Endpoint Protection and follow the security best practices. These will ensure your Windows OS stays safe no matter what.

Secure Your Enterprise Endpoints!

Why Endpoint Protection for Enterprise?

What to do if your company has been hacked?

Cyber Attack

Based on statistics it’s likely your company will come under the attack of hackers and cybercriminals at some point. In the UK, for example, 43% of businesses that participated in the Cyber Security Breaches 2018 survey reported that they’ve experienced a breach or an attack in that year alone.

It is important for companies to prepare for an attack now. Comodo Cybersecurity show you how to remediate and mitigate against these attacks.

Tips for Maximizing Cyber Crisis Management Efforts

1. Invest in Advanced Detection and Remediation Tools

The Ponemon Institute’s research showed that the faster a breach is identified and contained, the lower the costs the company incurs. A company that identifies a data breach saves $1 million if they see the issue within 100 days. Containing the cause of the breach is another matter. An organization that contains a breach within 30 days manages to save $1 million more in expenses that those that took longer.

In order to meet those timetables or even avoid encountering a breach altogether, companies need to invest in advanced network and endpoint security. Advanced scanning tools found in such blended solutions have a much higher chance of catching the root cause of breaches.

One such solution comes from Comodo. Comodo uses a Default Deny Approach in handling malware.  Comodo Advanced Endpoint Protection prevents breaches by immediately containing 100% executed unknown files until a trusted verdict is returned. When an unknown file, a potential malicious threat, attempts to execute on an endpoint, the file is immediately encapsulated by Auto-Containment Technology, while users can still run and open the unknown file without harm. While files are in Auto-Containment, they are sent to Comodo’s verdicting engine to be dynamically and statically analyzed in the cloud. 95% of unknown files return a verdict in under 45 seconds. The additional 5% of unknown files that need further investigation are sent to Comodo human analysts who return a verdict in less than 4 hours.

2. Form an Incident Response Team

The Ponemon Institute saw a $14 per record cost reduction during a breach for companies that had incident response teams during the crisis. According to the study, the average cost a company pays per member record compromised is $148. This is substantial if you think about the Equifax breach which affected at least 145.5 million users in the US. Based on the $148 cost per compromised record figure, Equifax should be spending around $21 billion. If Equifax had an incident response team during the time of the breach, they would have saved $2.3 billion.

3. Use Strong Encryption for Assets

Extensive use of encryption also saves companies $13 per member record compromised and possibly even more. A single cyber-attack can also lead to another since the threat actors can plant their assets into the system. These assets, like malware, can re-infect the system and open backdoors for another attack against the network.

What To Do in The First Minutes of an Attack

The employee who encounters the threat first needs to alert the IT and management teams.

When an employee encounters something irregular with their computer, they need to notify the IT team immediately. It doesn’t matter if it’s a false alarm, but if something is out of the ordinary, the techs need to know. There are times hackers and threat actors keep their attacks under the radar so they can steal data without issue. No one should take any irregularity for granted.

IT staff must disconnect the computer from the network and start documentation of the infection.

Once the tech team identifies the compromised computer, they need to remove it from the network immediately. They should start unplugging the LAN cables and move to contain the threat inside the unit. Aside from containing the threat, they will need to check nearby units for infection.

The company should check their backups in the cloud.

A member of the IT team needs to go to their existing backups and make sure they are not compromised in any way. The integrity of the backups will ensure the continuity of business operations after the attack is over and the team contains the bad actors.

The IT team on-site should start implementing cyber security protocols.

If a company creates a cyber security response plan, there should be rules and procedures for how to treat the first minutes of the discovery of a cyber-attack. If the incident response team is not yet on site, the first responders should start implementing what’s stated in the plan. If the plan calls for the scene of the cybercrime to be cordoned off, the IT team should preserve the integrity of that particular part of the network.

The IT team should call the attention of the employees and educate them about the attack or infection.

The company should immediately inform their affected employees about the cyber-attack. Human error can serve as the root cause of a breach and it can also definitely worsen a crisis. Employees need to learn how to act during such a situation in order to minimize and prevent further damage. For example, if the source of the threat is a phishing email, IT staff should immediately inform employees not to click or open a particular message to avoid any malware from spilling onto more computers.

Use security systems to track potential malicious assets.

Companies with security operations centers or blended solutions like Comodo Endpoint Security should definitely use their resources to make sure the threat is controlled. As we have previously mentioned, re-infection can still happen and it’s best that all trace of malware or security vulnerability be controlled as soon as the issue stabilizes.

How to Handle the Aftermath of a Cyber Attack

Once a breach or an attack happens, the company should try to resolve the issue in 30 days or less. During that time, the team should follow these steps in order to mitigate against all forms of damage:

Convene the Incident Response Team

The incident response team should be composed of an incident response manager, who may or may not be your CISO, several cybersecurity analysts and threat researchers. They’ll be at the heart of the investigation and also the ones coordinating with the representatives of the company’s various stakeholders. These representatives should hail from management, human resources, risk assessors, lawyers, and public relations experts. The internal tech team will investigate the cyber-attack while the other representatives will be there to support the work and to mitigate the kinds of damage that the company will encounter.

Cordon Off Assets and Ensure Cyber Security Integrity

The team should immediately control the scene and cut off part of the network that had been compromised. They also need to make sure that the root cause or causes of the attack or the breach aren’t still lingering in the system.

Once they ascertain everything is safe and that first responders or themselves have properly documented the incident, they’ll have to look at all of the assets within the company and check for damage. They should start consulting their detection technologies to make sure there are no additional threats within the network.

After the network has been secured, the team will need to help ensure that systems critical to business operations could be restored immediately. This step is crucial since stopping operations will only hurt the company more.

Document and Investigate

The investigating team will need to walk back through the incident to establish the facts. They’ll have to check what happened during the discovery of the attack and how the attack unfolded later on. These investigators also need to establish the kind of attack and its root causes.

Aside from reconstructing the narrative behind the cybercrime, the team should also document every step of the investigation. The investigation should always follow the steps prescribed by the cybersecurity plan and work in alignment with existing company policies every step of the way. This is important since auditors and investigators from the government will verify and check the extent of actions the company has taken to investigate and remediate the issue.

The team will also have to be sensitive about who they share the information with. Attacks and breaches can occur because of malicious insiders within the company. Once the team identifies who the culprit is behind the attack and who the accomplices are, the team should work with HR to ensure that the people are held accountable in accordance to company policy and the law.

Inform Law Enforcement and the Authorities

When a cyber-attack occurs, law enforcement must enter the picture as soon as possible. The problem with delaying this particular step is that it could be taken as a sign of culpability in the attack. Companies don’t report to the law following an attack because they think investigations can put a halt to operations. Agencies like the FBI will work in a non-disruptive way and cooperate with the victims of an attack.

Notify the Public Regarding the Attack and Engage with Media

There are some breaches that your company will be able to resolve in time before they blow up and no consumers get affected. When that’s the case, these breaches and attacks could be resolved without notifying the public. However, when customers will be affected by a breach, like in service businesses which actively engage with their clients, the company must make a disclosure.

When this happens, the company should own and control the narrative. The incident response team, together with the managers and people from human resources, should have a meeting before the disclosure to talk about every angle of the incident. The team should also stay in contact with a public relations expert who will help them manage how the company is portrayed in the media.

Follow Compliance Requirements After an Attack

Governments and states have become more sensitive to issues of breaches and attacks. Lawmakers have started making laws and policies which make companies accountable for any lack of preparation for the attacks carried out against their systems. In light of these regulations, companies need to make sure they conform to every letter of these requirements to avoid extensive penalties.

A major part of these regulations are the notification requirements. Certain laws like the European Union’s General Data Protection Regulation require companies to report to their clients about the breach within a 72-hour window.

Prep for Legal Consequences

The cold hard reality about a cyber-attack is that a company will never be fully prepared for one and all an organization can do in the aftermath of an attack is to do damage control. After your incident response team concludes its investigation, manages the story, and repairs the damage to structures within the company, they’ll have to work with the company’s legal team. The government or an individual will hold the company liable and there will be legal ramifications to what transpired.

The steps above should help you and your company weather the storm immediately after and within a month of a cyber-attack. This 30-day timeline is actually shorter than the actual period that a threat statistically lies dormant within a system which is around 180 days. That’s half a year that companies could actually have spent in mounting credible and proactive defenses against these threats.

If you’d rather avoid a cybersecurity breach entirely and prevent damage to your company’s reputation and finances, it’s time you invest in Comodo Cybersecurity’s Endpoint Protection System. Comodo Advanced Endpoint Protection (AEP) is designed on the notion that endpoint protection platforms must always verify and never trust unknown executables until proven safe with 100% verdicts, 100% of the time. By eliminating the “fear of the unknown,” Comodo AEP can prevent organizations from being breached, without impacting end user productivity.

What is Zero Trust?

what is zero trust

Zero Trust is a security concept centered on the fact that organizations should not automatically trust anything outside and inside its perimeters and instead must verify everything trying to connect to its systems prior to granting access. This extra layer of protection has been established to prevent data breaches.

Businesses are presently functioning more differently than they did just a few years ago. We find that devices, employees, and also applications are no longer locked inside the corporate perimeter. They are all on the web and hence a unique approach is needed to provide security for a whole new type of anywhere, anytime workers and cloud-based applications. Organizations are now moving away from solutions that secure the perimeter and are instead going towards employing a zero trust model in order to protect sensitive data and resources.

Zero Trust Definition

A zero trust security solution constantly evaluates trust every time a device or user requests access to a resource. This method prevents attackers from exploiting vulnerabilities in the perimeter to gain entry and then access confidential data and applications.

What is Zero Trust?

Key Principles and Technologies Behind Zero Trust Security

Zero trust security follows two key concepts: Never trust machines or users automatically, and least-privilege access.  Attackers exist within and outside the network and hence one should not automatically trust machines or users. Users should be given only limited access that they need in order to minimize each user’s exposure to sensitive parts of the network.

Multi-factor authentication  (MFA) is another key concept followed by zero trust security. This procedure will need additional evidence in order to authenticate a user. Hence, access cannot be gained by just entering a password. MFA is mostly used in the 2-factor authorization (2FA) employed on common online platforms like Google and Facebook. Besides entering a password, users who have enabled 2FA for these services will also have to enter a code sent to another device, thus supplying two bits of evidence that they are who they claim to be.

zero trust network architecture firm controls on device access. Zero trust systems will have to assess how different devices are attempting to gain access to their network and also guarantee that every device is authorized. This further reduces the attack surface of the network.

The concept of microsegmentation  is also employed by zero trust network architecture. This concept refers to the process of breaking up security perimeters into small zones in order to maintain separate access for separate parts of the network. For instance, a network containing files existing in a single data center that employs microsegmentation may comprise of dozens of separate, secure zones.

Security and Business Benefits offered by Zero Trust Security

Zero trust security will provide enterprises with the following security and business benefits:

  • Reduce complexity of the security stack Applying security with legacy technologies is greatly expensive and complicated. The standard perimeter mostly consists of hardware or virtual appliances for access control, security mechanisms, and application delivery and performance utilities. To operate in a global setting, these security stacks will have to be repeated for redundancy and high availability across data centers and regions. Each of these components will have to be separately purchased, installed, configured, and deployed for each data center in several localities. Administrators will be responsible for managing all of this equipment in-house by handling ongoing monitoring, troubleshooting, upgrades, and patching. Cloud-based zero trust models are capable of removing that complexity by moving all of these functions to a cloud-services approach.
  • Resolve security skills shortage With the ongoing spread of cybercrimes, threats are becoming more refined and tools are also available to help criminals in developing, installing, and monetizing templated attacks, such as ransomware-as-a-service and malware-as-a-service. Zero trust is employed in the cloud and because of this, organizations that adopt this process need not install a complicated stack of security equipment used for protecting all data centers. To secure all of their data, users, devices, and applications, organizations can just use a single service in the cloud. Besides decreasing the number of security professionals needed for monitoring, handling, updating, securing, and improving security controls, organizations employing zero trust will also be able to retask resources, assign business-critical efforts, and carry out proactive planning measures in order to more senior members of IT, eventually reducing costs.
  • Protect business and customer data After successfully getting onto an end-user machine within the firewall, malware will go ahead and exfiltrate customer data to a command and control (CnC) server placed outside of the network. Permitting sensitive and confidential customer data to go into the wrong hands can have grave consequences for both your business and your customers. Hence, zero trust security will help in safeguarding all such details and preventing them from being misused.
  • Deliver excellent security and end-user experience Users compromise on security when they try to remember complicated passwords by writing them down, or even by using easy-to-remember passwords. Secure access, ease to use, and productivity are offered by zero trust solutions. Cloud-based zero trust architecture is known to enhance the performance and help deliver a continuous user experience across a wide range of devices and network conditions.
  • Lower breach detection time and attain visibility into enterprise traffic Zero trust follows the principle that location is not an indicator of trust, hence the network is presumed to be hostile. The principle of “trust but verify” is replaced with “always verify and never trust”, with visibility being the foundation of verification.

What does Zero Trust Mean to an Organization?

With zero trust solutions you will be able to gain greater control in your cloud environment. Zero trust is a solution that is customized for all network types. It limits communication by permitting only workloads confirmed by their identity fingerprint to communicate. Zero trust architecture is application workload centric and because of this security teams have superior control over the application workload itself. It is not controlled by static network constructs that cause it to slow down. Adding 2-factor authentication and several other verification techniques will increase your potential to correctly verify users.

With zero trust cybersecurity solutions, organizations will thus be able to attain the security they need to protect their data and resources in today’s distributed organization. They will also be able to realize considerable business benefits. Besides enhancing visibility across the enterprise and lowering the breach detection time, enterprises will also be able to decrease the complexity of
their security stack, protect customer data to avoid reputational damage and major financial losses, and minimize the impact of the security skills shortage. At the same time, businesses will also enhance user experience and facilitate migration to the cloud via the adoption of a zero trust security solution.To help your organization gain benefits from a zero trust network, we at Comodo offer you with our endpoint security management, Provide Strong which focuses on effectively securing different endpoints, thereby securing a network by blocking access attempts and other risky activities at endpoints.

Endpoint security systems are a growing necessity in today’s threat landscape. With more enterprises employing practices like BYOD, endpoint security is thus becoming greatly relevant. Employees presently connect to company networks using their mobile devices or laptops, from their homes and also while traveling. Under such situations, security perimeters are likely to be undefinable and ever-shifting, and a centralized security solution will just not be suitable. This is where security endpoints come in as they will focus on supplementing centralized security measures along with extra layers of protection at endpoints, which are not just entry points for attacks and threats, but also points of outlet for sensitive data.

Comodo Advanced Endpoint Security software is available with seven layers of defense that include:

  • Web URL Filtering: Advanced interface to develop rules as needed.
  • Firewall: Offers supreme security against outbound and inbound threats, blocks personal data transmission by malicious software, and manages network connections.
  • Containment with auto-sandboxing: All unrecognized applications and processes are auto-sandboxed to run in a controlled environment.
  • Antivirus: Provides multiple technology-based automatic detection, cleansing and quarantining of doubtful files to eliminate viruses and malware.
  • Host Intrusion Protection System (HIPS): Monitors significant operating system activities to guarantee protection against malware intrusion.
  • File Lookup Services (FLS): Cloud-based instant analysis of strange files that checks file reputation against Comodo’s master blacklists and whitelist.

Ten Cyber Security Threats Facing Businesses Today


As technology continues to improve the quality of business infrastructure and speed up service delivery, it also introduces newer ways to exploit companies and threaten their business continuity. The 2018 Hiscox Cyber Readiness Report states that 7 out of 10 organizations failed in their cyber-readiness test which involves a company’s set cyber strategies and their processes and technology. One reason for failure is that companies do not adjust to the new cybersecurity landscape.

New companies and enterprises should be aware of the ever-evolving landscape of cyber threats and adjust their paradigms accordingly to survive. Small businesses with less than 100 employees hit by cybercrime incur damages from $24,000 to $63,000 while companies with 1000 employees or more can expect to suffer $1 million in damages. This is not counting the loss of customers when they lose trust in the companies after an attack and the damage to their brands.

If companies better understood the caliber of the threats they are facing, they would think more about their investment in cybersecurity.

Cybersecurity Threats Confronting Businesses in 2019

1. Fileless Malware:  Fileless malware gained the “fileless” moniker because it does not exist as files within the hard drive. Attackers program file-less malware to occupy the RAM. Threat analysts have a hard time finding traces of this kind of malware since it does not leave crumbs on the drive. Fileless malware turn visible only when programmers order it to initiate the attack.

Cybercriminals often deploy fileless malware against banks by inserting them into ATMs. The hackers in turn gain control of the cash machines. Another successful use hacker has for file-less malware is payload delivery. Fileless malware can unload ransomware to the system with the computer owner totally oblivious to what’s happening.

2. Crypto-Malware: The rise of cryptocurrencies and the explosive growth of Bitcoin in 2017 has also gained the attention of cybercriminals. Malware engineers developed malware which can actually mine cryptocurrency when the browser of an infected computer goes on the Internet. Although not directly harmful, crypto-malware proved to be disruptive as it steals a computer’s processing power to mine cryptocurrency. The infected computer bogs down and is noticeably slower in pulling up files and running programs. In time, the computer will break down because of the drain caused by the crypto-malware.

3. Zero-Day Threats: Software isn’t perfect right off the bat. Every program installs harbors security holes, called vulnerabilities, which hackers and cybercriminals can exploit. When they find a vulnerability and abuse it before the software developers can issue a fix for it, it’s considered a zero-day threat. Once the hackers get the ball rolling and use a program’s vulnerability to deliver ransomware or inject malicious code that’s a zero-day exploit. Imagine employees opening a Word document file and then it launches ransomware onto the system.

4. Meltdown and Spectre: Meltdown and Spectre are essentially vulnerabilities inside processor chips. What merits special mention for both vulnerabilities is that because there is an inherent flaw inside processors and it exists within such a low level of the system it’s hard to defend against hackers determined to exploit it. Hackers and malware engineers who take advantage of Meltdown and Spectre will be able to bypass current security measures without issue. They will also gain access to restricted parts of a computer’s memory and gain access to the user’s sensitive information.

5. IoT Malware: Sooner or later homes and businesses will host their own smart environments. They’ll employ sensors to gain information about the temperature, use apps to control the lighting, and attach energy-efficient cameras to monitor security. The problem is the firmware of these smart devices is also riddled with vulnerabilities. Hackers can exploit these vulnerabilities to control these smart devices. Imagine hackers switching lights off offices, halting power from flowing through smart plugs, or simply watching you from your smart surveillance system.

6. Banking Malware: Banking malware exists to steal financial information from users and deliver the information to hackers so cybercriminals can steal money from victims. Some banking malware specifically targets mobile users since smartphones now allow people to make online transactions. What’s sneaky about these kinds of malware is that their authors pass them off as apps you can download for Android like battery apps or games. This type of malware will work in the background and steal your data while you’re not aware.

Emotet, an incarnation of banking malware, is currently one of the more dangerous strains of malware out there. Basically, Emotet can change its form to avoid detection and then replicates itself within the system. It will move from one machine to the next by brute-forcing passwords to enter its next destination. This malware targets a user’s financial information, banking details, and even their Bitcoin purses.

7. Ransomware: Ransomware quickly rose through the ranks of malicious applications recently as one of the more noticeable threats. What’s alarming about this ransomware is its ability to lock down a computer and unlock it only after the owner pays a ransom. This system hi-jacking component makes ransomware very disruptive. The biggest ransomware attack initiated by the Cryptolocker strain infected around 250,000 computers and earned the ransomware authors $3 million. As you can imagine, attacks of this scale can practically cripple critical infrastructure and systems.

8. Stegware: Stegware expands malware’s attack surface. Hackers employ steganography which involves the act of hiding a malicious file inside another file, image, video, or message. At one point only the most veteran and well-versed of cybercriminals could actually craft their own stegware. However, cybercriminals have become savvier in producing them and make stegware available through kits in the Dark Web for even the amateurs to use. Companies will see more infections in the coming years resulting from these malicious files hiding under the cover of legitimate ones.

9. Phishing Email: Some degree of data breaches happens because of human error and the form of human error which leads to a breach happens when an employee clicks on a phishing email. A phishing email often carries a payload like ransomware or a trojan horse virus which wreaks havoc on the system right after its opened.

According to a 2015 McAfee survey, 97 percent of people can’t tell a phishing email from a legitimate email. For this reason institutions need to train employees to identify these threats and to avoid clicking them.

10. Advanced Persistent Threats: Finally, organizations should be wary of advanced persistent threats. They’re what you would call a “long con” when applied to a cyber-attack. Cybercriminals who are into APTs invest a lot of time casing their target after they’ve successfully infiltrated the system. Once they’ve gathered information, they’ll start capturing and transmitting data back to their own servers. This particular kind of attack is persistent in the sense that it can go on for years with the victim remaining unaware. Hackers who participate in APTs are dedicated professionals and often work in groups to penetrate their target organization.
Cyber Security Threats

A New Approach to Cybersecurity

C-Suite executives and managers note that Cybersecurity has been at the top of their list of concerns since 2016. They are correct to worry based on the growing list of cybersecurity threats above. Despite these concerns, of course, businesses must continue to flourish. The cybersecurity industry is also keeping up with these cybercriminals and creating innovations of their own to protect systems from these threats.

Cybersecurity Experts at Comodo recently gave insights on what cybersecurity approaches companies can adopt to prevent breaches. According to Comodo Cybersecurity Experts, organizations need to think about cybersecurity defense in layers. The first layer largely involves configuring the network in such a way that it discourages data leaks.

The next layer involves adding a layer of “bolt-on security” or a host of cybersecurity solutions which will augment a company’s existing cybersecurity defense structure. Finally, companies should add an analytical layer to these defenses which will allow cybersecurity teams to parse information and check for attacks. Advanced threat detection systems are part of this last analytical layer.

Comodo experts encourage companies to adopt new paradigms in the fight against advanced threats. Instead of just relying on purely reactive methods of detection and damage control, companies should invest in layers of solutions to achieve defense-in-depth to prevent breaches.

Comodo Cybersecurity’s security platform provides a proactive, zero trust security architecture that verdicts 100% of unknown files to prevent breaches originating from the web, email and cloud. To truly protect your business, Comodo Cybersecurity provides a combination of endpoint, network and cloud securities in a single platform to prevent breaches, while providing maximized visibility of your environment.

What is EDR?

Network Security Work

Endpoint Detection and Response (EDR) is a powerful event analysis tool that provides real-time monitoring and detection of malicious events on Windows endpoints. EDR Tool allows you to visualize threats in a detailed timeline while instantaneous alerts keep you informed if an attack occurs. In essence, EDR helps you prevent any malicious threats before they can even harm your Windows endpoint device.

EDR Definition

History of Endpoint Detection and Response

Endpoint Detection and Response was first coined by Anton Chuvakin, research director at the Gartner in July 2013. Endpoint threat Detection and Response was termed to define “the equipments that significantly focus on identifying and exploring malicious activities and other issues on the endpoints.” This is a new category of solutions, however the grouping of solutions are termed as EDR – Endpoint Detection and Response, this is at times compared to Advanced Threat Protection (ATP) in correspondance to overall security capabilities.

Endpoint detection and response is a rising innovation tending to the requirement for persistent checking and reaction to cutting edge dangers. One could even make the contention that endpoint detection and response is a type of cutting edge risk security.


Endpoint detection and reaction equipments work by observing endpoint and system occasions and recording the data in a focal database where facilitate examination, location, examination, detailing, and alarming occur. A product specialist introduced on have frameworks gives the establishment to occasion observing and announcing.

Continuous observing and recognition is encouraged using examination instruments, which distinguish assignments that can enhance the general condition of security by diverting regular attacks and encouraging early ID of progressing attacks – including insider dangers and outside attacks, and in addition empowering quick reaction to identified attacks.

Not all endpoint detection and reaction equipments work in correctly a similar way or offer an indistinguishable range of abilities from others in the space. For example, some endpoint detection and reaction apparatuses perform more examination on the operator, while others perform most information investigation on the backend by means of an administration support. Others fluctuate in gathering timing and scope or in their capacity to coordinate with threat intelligence providers, however all endpoint recognition and reaction instruments play out a similar fundamental capacities with a similar reason: to give a way to consistent investigation to promptly recognize, identify, and avoid propelled malicious threats.


While Anton Chuvakin authored the term endpoint detection and reaction keeping in mind the end goal to describle a set of instruments, the term may likewise be utilized to depict the capacities of an equipment with a substantially more extensive arrangement of security works as opposed to depict the device itself. For example, a device may offer endpoint location and reaction notwithstanding application control, information encryption, device control and encryption, control of user previlleges, control of network access, and an range of different capacities.
Equipment, both those delegated endpoint location and reaction devices and those offering EDR as a component of a more extensive arrangement of capacities, are reasonable for a huge number of endpoint perceivability utilize cases. Anton Chuvakin names a range of endpoint perceivability use cases falling inside three more extensive classes:

  1. Information search and examination
  2. Suspicious action identification
  3. Exploration of data

Most endpoint protection and reaction devices address the reaction part of these capacities through advanced investigation that distinguish designs and identify irregularities, for example, uncommon procedures, odd or unrecognized organizations, or other unsafe exercises hailed in view of standard examinations. This procedure can be computerized, with abnormalities activating alarms to prompt activity or further examination instantly, however numerous endpoint discovery and reaction devices take into account manual or client drove investigation of information too.

Endpoint detection and reaction is as yet a developing field, yet EDR capacities are rapidly turning into a basic component of any venture security arrangement. For companies that demands Advanced threat protection, endpoint detection and reaction is a sought after capability. The advantages brought by consistent visibility into all activities of data make endpoint detection response a profitable part of any security administration.

What is Firewall Security?

what is firewall security

In the computing world, the terminology firewall security refers to a network device which blocks certain kinds of network traffic. Actually, it acts as a barrier between a trusted and an untrusted network. The firewall security wall can be compared to a physical firewall in the sense that firewall security tries to block the spread of computer attacks.

Today, businesses have understood the need for firewall security, thereby they have firewall protection in place.

Different Types of Firewalls

what is firewall security

There are five different types of firewalls, keep reading to know about the similarities and differences between the five basic types of firewalls:

Packet filtering firewalls

The original type of firewall security is the Packet filtering firewalls which works inline at linking points where devices such as routers and switches do their work. It contains a list of firewall security rules that can stop traffic based on IP protocol, IP address and/or port number.

In other words, the Packet filtering firewalls compare each packet received to a set of established criteria. The troublesome Packets are flagged and are not forwarded and, therefore, are ceased to exist. On the brighter note, it better to have intrusion prevention in place alongside the firewall security to distinguish between regular web traffic and bad web traffic.

In an enterprise network, endpoint security or endpoint protection can be easily achieved using this.

Stateful inspection firewalls

The speciality of Stateful firewall is that it examines each packet like the Packet filtering firewalls and also keeps a track of whether or not that the packet is part of that particular established TCP session. In comparison other firewall security this offers more security but imposes a greater toll on network performance.

Deep packet inspection firewall

The Deep packet inspection firewall which is similar to intrusion prevention technology, examines the data in the packet, and can, therefore, look at application layer attacks. Due to its similarity with intrusion prevention technology, it is obvious that it provides some of the same functionality.

Application-level gateways

Technically a proxy, it is sometimes referred to as a proxy firewall protection. The Application-level gateways comprise a few of the attributes of packet filtering firewalls with those of circuit-level gateways.

One noticeable disadvantage is that the gateways that filter at the application layer offer significant data security, but they can dramatically affect network performance.

Benefits of Firewall Protection

  • Block attacks on your private network forced by other networks
  • Define a funnel and set-aside the non-authorized users.
  • Let firewall security monitor the network and computer and when questionable activity befalls, it will automatically generate an alarm.
  • Monitor and document services using FTP (File Transfer Protocol), WWW (World Wide Web), and other protocols.
  • Control the use of the Internet. Simply block inappropriate content.

Endpoint Firewall Protection

Comodo Endpoint Firewall Protection is the best choice that you have to watch-on and control all the network connections. It enables you to block or allow the traffic according to the rules configured. Further, it successfully deploys the detection and blocking rules required to oversee intrusions and network virus attacks that Trojans employ to infect.

Comodo Firewall is offered in the Comodo Endpoint Security Manager suite, beside the antivirus protection and centralized management. Matousec – a project run by a group of security experts who are focused on improving the security of end-users tested 33 PC firewalls, including Comodo Internet Security, each with 84 different tests. For the first time ever, a PC Security product has attained a perfect score, defending PCs against all proactive security challenges. We invite you to test it for yourself by downloading the endpoint protection on five Endpoints for free!

What is a Vulnerability Assessment?

Vulnerability Analysis Definition

Vulnerability Assessment as the name suggests is the process of recognizing, analyzing and ranking vulnerabilities in computers and other related systems to equip the IT personnel and management team with adequate knowledge about prevailing threats in the environment. With the appropriate information at hand, the risk factors can rightly be understood, and the required measures can be defined competently without any delay. Vulnerability Assessment is not specific to one industry and can be applied in all industries ranging from IT systems to Energy and other utility systems.

The Importance Of Vulnerability Assessment

Vulnerability assessment provides deep insights on security deficiencies in an environment and helps to evaluate a system’s vulnerability to a specific threat and the evolving ones. Simply put, an organization can fully understand the security flaws, overall risk, and assets that are vulnerable to cybersecurity breaches. To stay protected and to counter surprise attacks, a thorough vulnerability assessment can fix the unattended security issues.

Types of Vulnerability Assessments

Basically, a vulnerability assessment applies various methods, tools, and scanners to find out grey areas, threats, and risks. Everything depends on how well the weakness in the given systems is discovered to attend to that specific need. Find below different types of vulnerability assessment scans:vulnerability assessment

Network-based scans
Going by the name, it helps identify possible network security attacks. The scan helps zero-in the vulnerable systems on wired or wireless networks.

Host-based scans
Server workstations or other network hosts vulnerabilities are easily identified using these scans. In the process, ports and services are examined vigorously. It also provides excellent visibility into the configuration settings and patch history of scanned systems.

Wireless network scans
Wireless network infrastructure is scanned to identify vulnerabilities, it helps in validating a company’s network.

Application Scans
It is used to test websites to discover all known software vulnerabilities.

Database Scans
Database Scans aid in identifying grey areas in a database to prevent vicious attacks by cybercriminals.

Vulnerability Assessments Versus Penetration Testing

Penetration testing is ethical hacking, it is also known by the name pen testing. The given systems are tested which may include a computer system, network or web application to discover defense vulnerabilities that a cybercriminal can make use to exploit.

In most of the cases, a vulnerability assessment is often conducted with the help of a penetration testing component to recognize vulnerable areas in an organization’s procedures or processes that might not be detectable with network or system scans. In the technical terms, this process is seldom mentioned as penetration testing/vulnerability assessment or VAPT.

Penetration testing is not enough to get complete clarity of the prevailing vulnerabilities, as a matter of fact, it is one of the approaches. The procedure will reveal the appropriate ideas for mitigation to reduce or remove the risks. Furthermore, automated network security scanning tools provide reports on vulnerability assessment which need to be attended through evaluating specific attack goals or scenarios.

Enterprises must run vulnerability tests periodically to make sure their networks are safe. This is vital particularly when modifications are made, say for example when new services are added, new equipment is installed, or ports are opened.

On the other hand, penetration testing includes recognizing vulnerabilities in a network, therefore it encourages attacks on the system to derive the remediation formula. Even though it is carried out in harmony with vulnerability assessments, the main purpose of penetration testing is to investigate if a vulnerability really exists in the given systems. On the contrary, to prove that an exploit really exists, it can damage the network or application in the process.

Typically, a vulnerability assessment is customarily automated to include a range of unpatched vulnerabilities, penetration testing usually blends manual and automated techniques to help testers examine deeper of the vulnerabilities. It helps the testers to gain access to the network in a controlled environment.

Steps to Guide Vulnerability Assessment

With the data generated from vulnerability assessment, security professionals need to come up with ideas and ways to prevent and provoke online dangers. Grimly, that is not happening as they miss out cull out the right information from its automated report. If rightly approached, this can add a lot of value to the enterprise.

For enterprises that aim at gaining a strategic perspective regarding possible cybersecurity threats, the vulnerability assessment provides unique possibilities. What matters the most is the approach, sorting out the list one-by-one, and narrowing down on the issue. When there is a step-by-step approach in place the results from reports can be used to touch higher altitudes.

Be it an automated or manual vulnerability assessment tool, the steps proposed here will help you delve into an effective process that is productive and profitable for the organization.

Vulnerability Assessment Approach – Step 1

Even before you get started knowing your assets and their worth is important, so that you can decide on the critical value for each device. Plainly said, at least know the worth of the device that you have on your network or at least the devices that you will examine. Review the underlying facts whether the device is accessed by everyone in the facility or is it a kiosk or just administrators and authorized users. This information can throw a lot of details that you need to set right.

Once you have these details at hand you will be able to predict the below-stated points:

  • The impact of Risk
  • The threshold of Risk
  • Practices and policies for risk mitigation in each device
  • Suggesting the risk strategy
  • Remediation or Mitigation for each device or service
  • The analysis of business impact

Vulnerability Assessment Approach – Step 2

Get details of installed systems before the vulnerability assessment. It is a must to know what they are, what they do, and for who – also review the device open ports, processes, and services. Besides these, get a better knowledge of the certified drivers and software that need to be installed on the device and the basic configuration of each device. Collect public data and vulnerabilities concerning the device program, version, vendor and other related details.

Vulnerability Assessment Approach – Step 3

Make use of the right policy on the vulnerability scanner to achieve the anticipated effects. Before you run the vulnerability scan, check for any compliance requirements in accordance with the company’s posture and business. Once you have understood these factors, identify the best time and date to run the scan. It’s vital to identify the client industry context to plan if the scan can be run in one single shot or if segmentation is required. Get approval of the policy for the vulnerability scan to be performed.

Vulnerability Assessment Approach – Step 4

Vulnerability assessment report creation is the last and most important stage of all. It is important to pay attention to the details and combine extra value to the guidance phase. This will help you to gain true value from the report, add recommendations based on the original assessment objectives.

Based on the criticalness of the assets and results, add risk mitigation techniques. Point out the potential gap between the results and the system baseline definition. Also, suggest measures to set right the deviations and mitigate potential vulnerabilities. Conclusions drawn based on vulnerability assessment are very useful and are arranged in a way to guarantee the perception of the finding.

A detailed report needs to pack the below-mentioned points:

  • Vulnerability Name
  • Vulnerability Discovery Date
  • CVE – Common Vulnerabilities and Exposures Scores
  • A comprehensive explanation of the vulnerability
  • Affected Systems & its details
  • Information about the methods to fix the vulnerability
  • PoC of the vulnerability

What is Vulnerability Assessment

What is Virus Removal?

Cyber Security Threats

Virus removal refers to the process of automatically or manually disinfecting or deleting a computer virus, malware or any other malicious program on a computing device. The process is employed to shield a computer from possible data loss, corruption, or system inaccessibility.

A system virus removal follows the virus scan phase, which detects the virus and threat level. The virus can also be manually deleted, but this will need a strong understanding of viruses and the correct skills to reverse or remove registry entries. The user receives a failure message if a virus cannot be deleted.

Virus Protection

Virus protection software has been designed to prevent viruses, Trojan horses and worms from getting onto a computer and also to remove any malicious software code that has already infected a computer.

Most virus protection utilities bundle anti-malware and anti-spyware capabilities to go along with anti-virus protection. Internet security suites go one step further by including additional capabilities like anti-phishing, firewall, anti-spam, PC optimization, and file protection.

What can You do to Get Virus Protection?

Ensure to always keep your security software active and updated New viruses are released almost every day and hence there is always a chance for your computer to get infected by a virus that your antivirus software does not yet “know” about. 

Regularly update all your software You need to keep your computer’s operating system and other software updated because viruses often propagate by exploiting flaws in operating systems or commonly used programs. Whenever possible, configure your computer to download and install important updates automatically.

Deal with e-mail carefully Viruses are often propagated through e-mail attachments. Do not open attachments unless you are reasonably sure the e-mail is a genuine one

Only use e-mail services capable of scanning messages for viruses

Refrain from installing spyware and other software that may open backdoors which can be exploited

Types of Computer Viruses

Some of the common types of viruses include:

Direct Action Virus: This virus is “non-resident” and functions by selecting one or more files in order to infect each time the code gets executed. The main aim here is to copy itself and spread infection whenever the code gets executed.

Boot Sector Virus: This virus infects computer systems by copying code either to the partition table on a hard drive or the boot sector on a floppy disk. During startup, the virus gets loaded into memory. Following this process, the virus will infect any non-infected disks accessed by the system.

Macro Virus: This virus is written in a macro language and infects Microsoft Word or similar applications and causes a sequence of actions to be executed automatically when the application is started or if it gets triggered by something else.

Memory Resident Virus: Stays in memory after it executes and after its host program is terminated. On the other hand, non-memory-resident viruses are activated when an infected application runs.

Overwriting Virus: Copies its own code over the host computer system’s file data, which destroys the original program.

Cluster Virus: This virus links itself with the execution of programs by altering directory table entries in order to ensure that the virus itself will start when any program on the computer system is started. If infected by this virus, it will look as if all programs on your PC are infected; however, this virus is just in one place on the system.

Virus Protection vs Virus Removal

Virus protection software or antivirus software has been designed mainly to prevent infection, however, this software can also remove malware from an infected computer. Stand-alone system virus removal software or a malware remover provides a suitable way to find and remove malware from a computer in case the product already installed fails to do so.

Key difference between virus protection and virus removal software

Virus protection software is all about prevention as it is used to prevent files containing viruses from being downloaded onto your computer. It also prevents the virus from being activated if it somehow gets downloaded to your computer, placed in a file-like location or in memory. If the file is downloaded, but flagged by antivirus software as malware and prevented from being activated, it will cause any damage to your system even though the infected file will still need to be contained and deleted.

Assume a situation in which an infected file is downloaded and then run, making the virus active. This is usually done by accident, for instance, by opening a virus-infected file attachment in an email or clicking a malicious URL link.

Virus protection software may sometimes have rudimentary tools to remove active viruses, but modern malware is considered to be sophisticated in hiding on the infected computer where it can be re-initiated at a later time, hence these rudimentary tools may not completely remove infections.
System virus removal software provides tools that are used to specifically take malware out from an infected computer if a virus manages to pass through an antivirus software check. Malware here includes contained viruses, active viruses, and inactive malware that could be hidden and lurking on the infected computer.

Virus Removal from Your PC

If your PC does have a virus, adopt the following actions:

Remove the virus

Step 1: Enter Safe Mode

Turn your computer off and on again. Press the F8 button repeatedly as soon as you see anything on the screen. This brings up the Advanced Boot Options menu. Choose Safe Mode with Networking and press Enter. Keep your PC disconnected from the Internet.

Step 2: Delete Temporary Files

While in Safe Mode, you should delete your Temporary Files using the Disk Cleanup tool:

  • Go to the Start menu
  • All Programs (or just Programs)
  • Accessories
  • System Tools
  • Disk Cleanup
  • Scroll through the Files To Delete list, and then choose Temporary Files

Deleting these files could speed up the virus scanning you are about to do and could even help to get rid of a virus if it was programmed to start when your computer boots up.

Step 3: Download a Virus Scanner

Step 4: Run a Virus Scan

Recover or reinstall any damaged files or software

Assuming the scan identified and removed the virus, you may have to reinstall any files or programs that were damaged by the virus. This is where backups become useful, and you should make them regularly.

Improve your defences

Keep your protection up to date

Updating your virus protection software will help protect your PC against viruses and malware. Keeping it up to date is essential because new viruses are being developed all the time, hence even if you bought your antivirus a month ago, it could need immediate updating.

Make backups

Ensure to make regular backups of your files and store them on an external hard drive. This will help prevent the loss of vital information should you get another virus.

Take proactive measures to prevent getting another virus attack

Some quick things that will help in preventing you from downloading a virus again:

  • Install an antivirus program
  • Regularly back up your data
  • Install the latest software updates for Windows
  • Avoid clicking on pop-up messages that claim to have detected an issue with your computer
  • Be cautious of opening emails from addresses you do not recognize, particularly if they contain an attachment or a link
