Cisco Secure Access Control Server 4.1
Cisco Secure Access Control Server (ACS) provides a comprehensive, identity-based access control solution for Cisco intelligent information networks. It is the integration and control layer for managing enterprise network users, administrators, and the resources of the network infrastructure.
Cisco Secure ACS is available as a rack-mountable, dedicated appliance—Cisco Secure ACS Solution Engine—or as software that runs on Windows 2000 and 2003 platforms, Cisco Secure ACS for Windows. Both products provide secure, industry-leading authentication, authorization, and accounting (AAA) services to enterprises.

Product Overview
With an ever-increasing number of methods for accessing networks today, security breaches and uncontrolled user access are of primary concern among enterprises. With the wide adoption of IEEE 802.11 wireless LANs and ubiquitous broadband Internet connections, security challenges exist not only at the perimeter, but also inside a network. Identity networking technologies that can mitigate these security vulnerabilities have become of prime interest to customers worldwide. Stronger forms of authentication, such as public key infrastructure (PKI) and one-time passwords (OTPs), are increasingly used to control user access to corporate resources from public networks. Network administrators look for solutions that provide flexible authorization policies that are tied to the user identity, as well as to the network access type and the security of the machine used to access the network. Lastly, the ability to centrally track and monitor the connectivity of network users is of primary importance in isolating unwanted and excessive use of valuable network resources. Cisco Secure ACS is a highly scalable, high-performance access control server that operates as a centralized RADIUS and TACACS+ server. It extends access security by combining authentication, user access, and administrator access with policy control within a centralized identity networking solution, allowing greater flexibility and mobility, increased security, and user-productivity gains. It enforces a uniform security policy for all users regardless of how they access the network. It reduces the administrative and management burden involved in scaling user and network administrator access to the network. By using a central database for all user accounts, Cisco Secure ACS centralizes the control of all user privileges and distributes them to hundreds or thousands of access points throughout the network. As an accounting service, Cisco Secure ACS provides detailed reporting and monitoring capabilities of network users' behavior and keeps a record of every access connection and device configuration change across the entire network. This feature has become extremely important for organizations in complying with Sarbanes-Oxley Act regulations. Cisco Secure ACS supports a broad variety of access connections, including wired and wireless LAN, dialup, broadband, content, storage, voice over IP (VoIP), firewalls, and VPNs. Cisco Secure ACS is an important component of the Cisco Identity-Based Networking Services (IBNS) architecture. Cisco IBNS is based on port-security standards such as 802.1x (an IEEE standard for port-based network access control) and Extensible Authentication Protocol (EAP),
