TACACS+

TACACS+ (Terminal Access Controller Access-Control System Plus) is a protocol used by organizations to securely manage and control remote access to their network devices like routers and switches. It verifies user identities, enforces permissions, and logs activities to ensure that only authorized personnel can access sensitive systems. Unlike other protocols, TACACS+ encrypts the entire communication between the user and the device, providing a high level of security and central control over user authentication and command authorization. This makes it a reliable choice for maintaining network security in enterprise environments.
