The NAC Appliance (Cisco Clean Access) is a “shrink-wrapped” network admission control solution that recognizes users, their devices and roles, evaluates the security posture of the endpoint and scans for vulnerabilities, and enforces policy in the network. In particular, prior to allowing users onto the network, the NAC Appliance solution allows administrators to authenticate, authorize, interrogate, and remediate users and their machines, enforcing policy based access control on the network. We recommend CCNA Security, CCSP, BSMCN, SNRS, and BSCI as prerequisites to this course. Students should also be familiar with the Microsoft Windows operating system, networking and security terminology and concepts, and implementation of network security.
