Network access control systems are tools used for controlling and managing network access based on compliance with a network and its policies. These policies are devised based on various parameters like user identity, device location, device health, among others.
The same philosophy is someone requiring a username and password to connect to your Network remotely via VPN, or use a Wifi Password or Domain Credentials present some sort of Network Access Control. But what happens when you look at the Physical layer , what happens when someone brings their home computer and plugs it into the network or even worse an attacker plugs in?
NAC systems present an authentication layer on the physical port so only devices with a working AntiVirus and Windows patches and correct credentials will be presented on the company network. You can even present a two factor authentication to this incase the user details get compromised. If any of these tests fail they will be redirected to the Guest Networks
Systems that help managed this are HP's Aruba ClearPass or Cisco's ISE
