The Basics Of Network Security

Nowadays network security is gaining more popularity because of the increase in cyber-crimes and identity theft crimes.

If you seriously want to protect your office data then you need to know about the network access control rather than just knowing the router and firewall.

Network Access Control (NAC) is the method through which access to a network is determined and safeguards computer systems from illegal access and is fragmented into four basic modules: Authentication, enforcement, endpoint security, and management.

Authentication – This process of control is the chief in a series of network security methods. It is most often controlled by firewalls and validates what should and should not have admittance to the network.

Enforcement – This part of network security tells about the authenticated clients and that client never becomes a risk to the network security once admittance is permitted.

Endpoint Security – This component is described as being both individually and centrally managed. In this part of security anti-viruses are used to detect any worn or Trojan horse type virus.

Network Management – It links together all other modules that changes to meet client requirements and comprises of constant tracking of the network.
