Product Overview
With the ever-increasing number of methods and opportunities for accessing networks today, security breaches and uncontrolled user access are of primary concern among enterprises. While the wide deployment of wireless LANs and remote access have increased security challenges at the perimeter, security risks inside the enterprise exist as well. Identity networking technologies such as 802.1x that can mitigate both internal and external security vulnerabilities have become of prime interest to customers worldwide. Network security officers and administrators need solutions that support flexible authentication and authorization policies that are tied to the user identity as well as context such as the network access type and the security of the machine used to access the network. Further, there is a need to audit network use and monitor corporate compliance.
Cisco Secure ACS is a highly scalable, high-performance access policy system that centralizes authentication, user access, and administrator access policy and reduces the administrative and management burden. Cisco Secure ACS is a central point for administering security policy for users and devices accessing the network. Cisco Secure ACS supports multiple and concurrent access scenarios including:

-Device administration: Cisco Secure ACS authenticates network administrators, authorizes commands, and provides an audit trail.
-Remote Access: Cisco Secure ACS works with VPN and other remote network access devices to enforce access policies.
-Wireless: Cisco Secure ACS authenticates and authorizes wireless users and hosts and enforces wireless-specific policies.
-802.1x LAN: Cisco Secure ACS supports dynamic provisioning of VLANs and access control lists (ACLs) on a per user basis and 802.1x with port-based security.
-Network admission control: Cisco Secure ACS communicates with posture and audit servers to enforce admission control policies.
