| 4.3.3 |  | Overview of Cisco Secure ACS for UNIX |

| Cisco Secure ACS 2.3 for UNIX is used to authenticate users and determine which internal networks and services they may access. By authenticating users against a database of user and group profiles, Cisco Secure ACS for UNIX effectively secures private enterprise and service provider networks from unauthorized access.

Cisco Secure ACS for UNIX incorporates a multi-user, web-based Java configuration and management tool that simplifies server administration and enables multiple system administrators to simultaneously manage security services from multiple locations. The GUI supports Microsoft and Netscape Web browsers, providing multi-platform compatibility and offering secure administration via the industry-standard Secure Socket Layer (SSL) communication mechanism.

Token cards from CryptoCard, Secure Computing Corporation, and Security Dynamics Technologies are supported. Token cards are the strongest available method used to authenticate users dialing in and prevent unauthorized users from accessing proprietary information. Cisco Secure ACS for UNIX also supports relational database technologies from Sybase Inc. and Oracle Corporation. Traditional scalability, redundancy, and non-distributed architecture limitations are removed with the integration of relational database technologies such as the Sybase SQL Anywhere. Storage and management of user and group profile information is greatly simplified.
