Question # 23
Describe how Network Access Control (NAC) works.
Network Access Control assesses the condition of a device before allowing connection to a network. Any system not meeting the minimum security requirements is placed in quarantine and allowed to correct deficiencies before retesting against the NAC for access.
NAC examines the current state of a system or network device before it is allowed to connect to the network. Any device that does not meet a specified set of criteria, such as having the most current anti-virus signature or the software firewall properly enabled, is only allowed to connect to a “quarantine” network where the security deficiencies are corrected. After the problems are solved, the device is connected to the normal network. The goal of NAC is to prevent computers with suboptimal security from potentially infecting other computers through the network.
