What Is Network Security?

Forensic Analysis Tool

Network security is an organization’s strategy that enables guaranteeing the security of its assets including all network traffic. It includes both software and hardware technologies. Access to the network is managed by effective network security, which targets a wide range of threats and then arrests them from spreading or entering in the network.

Network Security Definition And Meaning

Network security is an integration of multiple layers of defenses in the network and at the network. Policies and controls are implemented by each network security layer. Access to networks is gained by authorized users, whereas, malicious actors are indeed blocked from executing threats and exploits.Network Security Wiki

Our world has presently been transformed by digitization, resulting in changes in almost all our daily activities. It is essential for all organizations to protect their networks if they aim at delivering the services demanded by employees and customers. This eventually protects the reputation of your organization. With hackers increasing and becoming smarter day by day, the need to utilize network security tool becomes more and more impotent.

Types of Network Security

  • Antivirus and Antimalware Software
  • Application Security
  • Behavioral Analytics
  • Data Loss Prevention (DLP)
  • Email Security
  • Firewalls
  • Mobile Device Security
  • Network Segmentation
  • Security Information and Event Management (SIEM)
  • Virtual Private Network (VPN)
  • Web Security
  • Wireless Security
  • Endpoint Security
  • Network Access Control (NAC)

Antivirus and Antimalware Software : This software is used for protecting against malware, which includes spyware, ransomware, Trojans, worms, and viruses. Malware can also become very dangerous as it can infect a network and then remain calm for days or even weeks. This software handles this threat by scanning for malware entry and regularly tracks files afterward in order to detect anomalies, remove malware, and fix damage.

Application Security: It is important to have an application security since no app is created perfectly. It is possible for any application to comprise of vulnerabilities, or holes, that are used by attackers to enter your network. Application security thus encompasses the software, hardware, and processes you select for closing those holes.

Behavioral Analytics: In order to detect abnormal network behaviour, you will have to know what normal behavior looks like. Behavioral analytics tools are capable of automatically discerning activities that deviate from the norm. Your security team will thus be able to efficiently detect indicators of compromise that pose a potential problem and rapidly remediate threats.

Data Loss Prevention (DLP): Organizations should guarantee that their staff does not send sensitive information outside the network. They should thus use DLP technologies, network security measures, that prevent people from uploading, forwarding, or even printing vital information in an unsafe manner.

Email Security: Email gateways are considered to be the number one threat vector for a security breach. Attackers use social engineering tactics and personal information in order to build refined phishing campaigns to deceive recipients and then send them to sites serving up malware. An email security application is capable of blocking incoming attacks and controlling outbound messages in order to prevent the loss of sensitive data.

Firewalls: Firewalls place a barrier between your trusted internal network and untrusted outside networks, like the Internet. A set of defined rules are employed to block or allow traffic. A firewall can be software, hardware, or both. The free firewall efficiently manages traffic on your PC, monitors in/out connections, and secures all connections when you are online.

Intrusion Prevention System (IPS): An IPS is a network security capable of scanning network traffic in order to actively block attacks. The IPS Setting interface permits the administrator to configure the ruleset updates for Snort. It is possible to schedule the ruleset updates allowing them to automatically run at particular intervals and these updates can be run manually on demand.

Mobile Device Security: Mobile devices and apps are increasingly being targeted by cybercriminals. 90% of IT organizations could very soon support corporate applications on personal mobile devices. There is indeed the necessity for you to control which devices can access your network. It is also necessary to configure their connections in order to keep network traffic private.

Network Segmentation: Software-defined segmentation places network traffic into varied classifications and makes enforcing security policies a lot easier. The classifications are ideally based on endpoint identity, not just IP addresses. Rights can be accessed based on location, role, and more so that the right people get the correct level of access and suspicious devices are thus contained and remediated.

Security Information and Event Management (SIEM): SIEM products bring together all the information needed by your security staff in order to identify and respond to threats. These products are available in different forms, including virtual and physical appliances and server software.

Virtual Private Network (VPN): A VPN is another type of network security capable of encrypting the connection from an endpoint to a network, mostly over the Internet. A remote-access VPN typically uses IPsec or Secure Sockets Layer in order to authenticate the communication between network and device.

Web Security: A perfect web security solution will help in controlling your staff’s web use, denying access to malicious websites, and blocking

Wireless Security: The mobile office movement is presently gaining momentum along with wireless networks and access points. However, wireless networks are not as secure as wired ones and this makes way for hackers to enter. It is thus essential for the wireless security to be strong. It should be noted that without stringent security measures installing a wireless LAN could be like placing Ethernet ports everywhere. Products specifically designed for protecting a wireless network will have to be used in order to prevent an exploit from taking place.

Endpoint Security: Endpoint Security, also known Network Protection or Network Security, is a methodology used for protecting corporate networks when accessed through remote devices such as laptops or several other wireless devices and mobile devices. For instance, Comodo Advanced Endpoint Protection software presents seven layers of defense that include viruscope, file reputation, auto-sandbox, host intrusion prevention, web URL filtering, firewall, and antivirus software. All this is offered under a single offering in order to protect them from both unknown and known threats.

Network Access Control (NAC): This network security process helps you to control who can access your network. It is essential to recognize each device and user in order to keep out potential attackers. This indeed will help you to enforce your security policies. Noncompliant endpoint devices can be given only limited access or just blocked.

Technical Network Protection: Technical Network Protection is used to protect data within the network. Technical network protection guards both stored and in-transit data from malicious software and from unauthorized persons.

Physical Network Protection: Physical Network Protection, or Physical Network Security, is a network security measure designed to prevent unauthorized people from physically interfering with network components. Door locks and ID passes are essential components of physical network protection.

Administrative Network Protection: Administrative Network Protection is a security method that control a user’s network behaviour and access. It also provides a standard operating procedure for IT officers when executing changes in the IT infrastructure. Company policies and procedures are forms of Administrative network protection.

What is Data Security?

data security

The terminology “Data security” refers to the protective measures of securing data from unapproved access and data corruption throughout the data lifecycle. Today, data security is an important aspect of IT companies of every size and type. In the process, they deploy data security solutions which include tokenization, data encryption, and key management practices that protect data.

Data security is also known as System Data Security, Information Security or Computer security.

Why Data Security Solutions?

Data is an important asset to any organization and thereby, it is essential to safeguard it from online criminals. Organizations across the globe are investing heavily in information technology (IT) to deploy the best of cyber defense capabilities.

Basically, organizations are focused on protecting three common elements namely people, processes, and technology. This inwardly protects intellectual capital, critical infrastructure, customer information, brand and much more. Data security is not just important for organizations. Data protection comes into play on the personal computer, tablet, and mobile devices which could be the next target of cybercriminals.

Normally, remote devices that connect with an organization get targeted by attackers to tap the sensitive information. This is were the endpoint protection, endpoint security comes into play, it helps to protect and maintain the devices connecting the network.

Data breaches and cyber-attacks are anticipated to increase in the due course of time as the computer networks expand. It is important to have the right Data Security Solutions in place to meet the challenging threats.

Types of Data Security and their Importance

Data security software protects a computer/network from online threats when connected to the internet. The data security software may also protect other areas such as programs or operating-system for an entire application. Its goal is to recognize rules and actions to apply against strikes on internet security. There are several types of security, and they are:

Network Layer Security

The cryptographic techniques also protect TCP/IP (Internet protocol) alongside other internet protocols that have been designed for protecting emails on the internet. The techniques include SSL and TLS for the traffic of the website, PGP for email and for network security its backed by IPSec.

IPSec Protocol

The IPSec Protocol was initially developed for guarding interaction using TCP/IP. It was designed by the IETF, and it provides security and verification by using the method of cryptography, the data is modified using security methods. The two main aspects of modification that form the reasons for IPSec are Authentication Header (AH) and Encapsulating Security Payload (ESP).

Email Security

The protective measures employed to safeguard the access and content of an email account or service is called Email Security. Basically, the electronic mail is composed, saved, and delivered in multiple step-by-step procedures that start with the message’s structure. An email security software is implemented by the service provider to secure subscriber email accounts and data from hackers.

Data Security vs. System Security

Data security refers to the efforts that an organization takes to guarantee that the information stored isn’t deliberately accessed or accidentally deleted or modified, manipulated or otherwise abused for illegal money-making. System security works closely associating with data security. System security protects everything that an organization wants to ensure in its networks and resources. Simply put, data security is meant to protect the information and system security is what protects the information containing the devices and network. Comodo offers one of the best 360 degree protection for data and resources.

Lets quickly go through some of the common techniques of cyber attacks. Know how your organization can mitigate these risks.

Backdoor Attack – Not all the computer networks are secure as they seem. Seldom programmers leave codes open that enable the troublemakers to access a network completely. As a matter of fact, cybercriminals look for such exploits and make use of the weak points. Always be vigilant to review the code for any customized software used on your organization and that software-as-a-service and platform-as-a-service suppliers are not vulnerable to these kinds of attacks.

Denial of Service (DoS) Attack- Instead of sneaking into a computer network to loot valuable data, malicious people may try overpowering the network by trafficking it with loads of requests for service, slowing access and network-reliant operations to a crawl. A usual denial of service attack can be stopped by blocking the attacker’s IP address. However, a more complicated attack type, distributed denial of service (DDoS) attack, is difficult to hold, as it includes numerous IP addresses. But, today many vendors market solutions that decrease the effects of DDoS attacks.

Direct Access Attack- People accessing physical assets in your organization would easily access your most confidential information. Fraudsters who desperately want to lift the data can easily steal hard drives, flash drives, and laptops or break into your office, and copy the information they want. Thereby, it is safer to heighten security by providing employee training, and information encryption.

Malware Attack- Malicious software/malware attack are very common these days. An intruder gains access to the computer network and then encrypts all the valuable data without a trace. In order to access your data, you need to get the encryption key, and you must pay a ransom. The payments are made through bitcoin and there are possibilities that the ransom escalates in price over time. Malicious programs sneak into your system or network through a virus or worm, so instruct the employees about the online threat of clicking on suspicious linkings or opening unknown attachments.
