| CiscoSecure ACS can be used with either TACACS+ or RADIUS, or both can be used simultaneously. CRYPTOcard, Secure Computing, and Security Dynamics token card servers are also supported. Additionally, CiscoSecure ACS is capable of encrypting transmissions, which enables password protection. If CiscoSecure is running on Solaris 2.5 or greater, the administrator can limit the number of user sessions and disable an account after a specified number of login attempts.
