Cisco Clean Access is the solution that Cisco acquired from Perfigo in 2004.This solution provides the capability to:
- Authenticate users using a web browser (similar to the guest authentication solution).
- Evaluate host compliance with security policies
- continue access to the network for the hosts depending on the result of the above two actions
There are three main components to this solution:
1. Cisco Clean Access Server (CAS): This is the appliance that acts as the authenticator using the browser based authentication mechanism.
2. Cisco Clean Access Agent (CAA): This agent is downloaded to the client machine attempting to access the network to evaluate the health and integrity of the host.
3. Cisco Clean Access Manager (CAM): This is the out of band management server where the security policies are configured.
