® Secure Access Control System (ACS) is a centralized identity and access policy solution that ties together an enterprise's network access policy and identity strategy. Cisco Secure ACS 5.2 is a next-generation platform that delivers major capabilities, including:
• A powerful, attribute-driven rules-based policy model that addresses complex policy needs in a flexible manner
• A lightweight, web-based graphical user interface (GUI) with intuitive navigation and workflow
• Integrated advanced monitoring, reporting, and troubleshooting capabilities for maximum control and visibility
• Improved integration with external identity and policy databases, including Windows Active Directory and Lightweight Directory Access Protocol (LDAP)-accessible databases, simplifying policy configuration and maintenance
• A new distributed architecture for large-scale deployments
Cisco Secure ACS 5.2 is currently orderable. Customers interested in purchasing this product can place orders through their normal sales channels.
Cisco Secure ACS 5.2 is offered as three different options:
• The Cisco 1121 Access Control System appliance
• Software upgrade for existing Cisco 1120 Access Control System appliances
• Software appliance available for installing as a virtual machine into VMware ESX
All versions of Cisco Secure ACS 5.2 run the same software image and support the same features. For system specifications, please view the Cisco Secure ACS 5.2 data sheet at
The appliance and VMware versions each include a Base license. The Base license is required for each Cisco Secure ACS 5.2 appliance or software instance in a network.
With the Base license, Cisco Secure ACS 5.2 appliances or software virtual machines can support deployments of up to 500 network devices (authentication, authorization, and accounting [AAA] clients). The number of network devices is based on how many unique IP addresses are configured. This is not a limit for each individual appliance or instance, but a deployment-wide limit that applies to a set of ACS instances (primary and secondary) that are configured for replication.
The optional Large Deployment add-on license allows a deployment to support more than 500 network devices. Only one Large Deployment license is required per deployment as it is shared by all instances.
The optional Security Group Access System license is required to enable Security Group Access (SGA) and 802.1ae (also known as MACSec) functionality. Only one Security Group Access System license is required per deployment as it is shared by all instances.
To order Cisco Secure ACS 5.2 you must order one of the Base product part numbers shown in Table 1. If you are upgrading an existing ACS deployment, you will need to order a product part number from Table 3 or Table 4.
