The Cisco Secure Access Control Server (ACS) is a high-performance, highly scalable, centralized user access control framework. Cisco Secure ACS offers centralized command and control for all user authentication, authorization, and accounting from a Web-based, graphical interface, and distributes those controls to hundreds or thousands of access gateways in your network. With ACS you can manage and administer user access for Cisco IOS¨ routers, virtual private networks (VPNs), firewalls, dial and broadband DSL, cable access solutions, voice over IP (VoIP), Cisco wireless solutions, and Cisco Catalyst¨ switches via IEEE 802.1x access control.

With a Wireless LAN you can now:

• Take your network with you when your office relocates.
• Add new employees to the network without rewiring.
• Get fast network access from your laptop in a meeting room or elsewhere in your office.
• Be connected to a network even in difficult-to-wire locations.
• Obtain an easily managed network without having to replace your existing LAN.

Cisco Aironet addresses the key network concerns of mid-size customers, such as how to better utilize office space, how to provide network access to an increasingly mobile workforce and how to make better use of conference rooms, cafeterias and hard-to-wire areas.

How it works:
Through a combination of Cisco wired and Wireless LAN infrastructure, medium- to large-sized businesses are able to deploy Cisco Aironet WLAN solutions, allowing employees constant access to the network from anywhere in the office. By running Cisco Aironet Access Points (APs) from switches such as Cisco Catalyst 3550, multiple access points can be setup in one common area allowing for complete physical floor coverage, including conference rooms or meeting areas.

When the AP is coupled with a Remote Access Dial-In User Service (RADIUS) that supports the same authentication types (such as with Cisco Secure Access Control Server, ACS 2.6), the result is a scalable, centrally managed security solution. Wireless clients are provided with secure network links through the generation and distribution of 128-bit encryption keys that are unique for each user and for each session.
