About this Course

This course teaches students how to provide secure access to network resources by using the Cisco Secure Access Control System (ACS) version 5.2, which interoperates with security features in Cisco IOS Software.

Students will gain a thorough understanding of the operation of the Cisco Secure ACS to control access to network services and devices. Course subjects include the principles of authentication (identifying users and devices in order to control access to networks, services, and devices), authorization (restricting the functions that users can perform on services and devices) and accounting (to track the activities of users). The RADIUS, TACACS+, Extensible Authentication Protocol (EAP), and IEEE 802.1X protocols are discussed in theory and practice as the basis of network security. Specific methods and configurations are shown that can be used in your production networks to achieve targeted and detailed control objectives. The course includes hands-on labs to provide direct experience in configuring Cisco Secure ACS and Cisco network devices.
