Network Access Control
Network Access Control – also referred to as Network Admission Control. A traditional network server (NAS) is a server that performs authentication and authorization functions for potential users by verifying logon information. In addition to these functions, NAC restricts the data that each particular user can access, as well as implementing anti-threat applications such as firewalls, antivirus software and spyware detection programs. NAC also regulates and restricts the things individual can do once they are connected.
