Network security is designed to protect the usability of the system. It is common for hackers to log into data networks and steal access. Network security systems are designed to prevent cyber security attacks, malware attacks, and unauthorized access. Moreover, a network security system contains information on processes, policies, and practices designed to prevent, detect, monitor, and denial of computer access and its data. A network security system uses software as well as hardware technologies to protect the system.

All organizations, regardless of size and type, need to secure their networks. Cyber security attacks have become common; as a result, many organizations suffer financial losses and data breaches. Hackers are always looking for ways to find loopholes in networking systems to gain easy access. However, there are many network security tools in place to prevent cyber-attacks and keep the system safe.

This blog is going to be a comprehensive guide on the network security system; how it works, and what its components are.

Working Principle of a Network Security System

There are layers of a network security system. When an organization chooses a network system, it needs security at all levels. Cyber security attacks can target any component of an organization’s data. Therefore, network security systems are designed in the form of layers for difficult access. Network security systems are divided into three types, namely physical network security, technical network security, and administrative network security.

Physical Network Security 

Physical network security prevents gaining physical access to a network’s components. For instance biometric locks, cables, routers.

Technical Network Security 

Technical network security secures the data exchange that takes place online. It makes sure that the transfer is one-to-one, without third-party intervention. This system protects data from hackers as well as from employees who are denied access.

Administrative Network Security

Administrative network security control user authentication, level of access, and changes brought by IT staff.

Components of Network Security

Network Access Control

The risk for a data breach has spiked due to work-from-home situations. NAC controls the access to the network and monitors traffic on an organization’s network. Hence, it increases a system’s visibility so suspicious activities can be prevented timely.

IP System

An intrusion prevention system detects and examines malware. IPS blocks suspicious activities. It gathers information on potential malware that threatens network security.

Firewall Security

A firewall is an integral tool for network security. It monitors incoming and outgoing traffic. It blocks unauthorized access and controls the spread of malware and virus.

Security Information and Event Management

SIEM combines two cutting-edge technologies, namely security information management and security event management. It collects suspicious activities from various systems and then uses them to create an alert for the employees.
