About the Cisco NAC Appliance
Cisco® NAC Appliance (formerly Cisco Clean Access) is a Network Admission Control (NAC)
product that allows network administrators to authenticate, authorize, evaluate, and remediate wired,
wireless, and remote users and their machines prior to allowing users onto the network. It identifies
whether networked devices such as laptops, desktops, and corporate assets are compliant with a
network's security policies, and it repairs any vulnerabilities before permitting access to the network.
Cisco NAC Appliance is a network-centric integrated solution administered from the web console of
the Clean Access Manager (CAM), enforced through the Clean Access Server (CAS), and applied on
clients through the Clean Access Agent and Cisco NAC Web Agent client software. You can deploy the
Cisco NAC Appliance solution in the configuration that best meets the needs of your network.
The Cisco NAC Appliance is a Linux-based network hardware appliance which is pre-installed with
either the CAM (MANAGER) or CAS (SERVER) application, the operating system and all relevant
components on a dedicated server machine. The operating system comprises a hardened Linux kernel
based on a Fedora core. Cisco NAC Appliance does not support the installation of any other packages
or applications onto a CAM or CAS dedicated machine.
