Advantages of Network Access Control
Network access control systems are used in organizations today to protect their network from infection which can cause damage to the entire system. Here are some of the advantages of network access control.
One of the benefits of network access control systems is that it prevent computers that lack an anti-virus or patches from accessing a network because they will place other computers at risk. It scans the user when they are requesting access to the network and also controls the computer.
Network access control systems are also useful in both large and small organizations. Large organizations usually face the challenge of securing their network access due to due to the large numbers of employees, devices, and offices, hence NAC is useful in such companies.
An additional reason why you should a network access control system is because it provides quicker registration and access to the network provided the computer comply with the regulations. Unlike manual processing, the request to access the network will not take several days but will be processed on the same day.
Organizations that use the network access control system will be guaranteed of a more secure network because it prevents infection and attacks from viruses, bots, and other serious malware. It also helps individuals who don’t have access to a secure network by providing them with a higher level of security.
Also, the network access control system scans each computer that tries to access the network in order to ensure that it is updated with antivirus software and patches. If a computer does not meet those requirements, it will be assigned to a LAN that is routed to patch only and it will not be assigned to rest of the network. This ensures that users with outdated or computer worms do not access the network.
It also helps organizations to manage the numerous endpoints that are connected to the network. This protects the network and the endpoints from comprised devices. It also allows the operator to create some policies and enforce them, for instance, the type of computers that will be allowed to access the network.
During an attack, the NAC is allowed to quarantine the machine and examine the seriousness of the attack. After NAC evaluates the attack, it will monitor and manage guests in order to identify any invasion.
It also validates all the endpoints regardless the agent running it or the operating system involved. It can exempt some endpoints so that they are not checked with the other endpoints. Lastly, it protects all the access methods used by the endpoints to connect to the network including the campus switching and remote access.
