TACACS+ (Terminal Access Controller Access-Control System Plus) is a network authentication protocol used to centrally manage authentication, authorization, and accounting (AAA) for users accessing network devices and systems. It enables organizations to control who can access infrastructure components, what actions they are permitted to perform, and to log those activities for auditing purposes. TACACS+ is widely used in enterprise and critical infrastructure environments where strong access control and traceability are required.
