TACACS+ (Terminal Access Controller Access-Control System) and RADIUS (Remote Access Dial-In User Service) are used to control access to legacy network devices via SSH/TELNET sessions. 


Single Connect has built-in and pre-integrated TACACS+ and RADIUS servers that provide AAA (Authentication, Authorization and Accounting) services for the network infrastructure.
