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.
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.
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.
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.

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.
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.
HOW EDR WORKS?
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.
ENDPOINT DETECTION AND RESPONSE: NOT JUST TOOLS, BUT CAPABILITIES
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:
Information search and examination
Suspicious action identification
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.
