What does TACACS+ provide for network communication?

• A. Encryption for wireless communications
• B. Authentication, authorization, and accounting (AAA) services
• C. Network traffic analysis
• D. Device configuration management

Answer: (B)

TACACS+, which stands for Terminal Access Controller Access-Control System Plus, is a protocol that primarily focuses on providing Authentication, Authorization, and Accounting (AAA) services for network devices. When a user attempts to gain access to a network resource, TACACS+ verifies the user's identity through authentication processes. After confirming a user's identity, the protocol handles authorization, determining what resources the authenticated user can access and what operations they are allowed to perform. Finally, TACACS+ records accounting data, which can be used for auditing and monitoring activities. This comprehensive approach to managing network access and security makes TACACS+ a crucial component in network communication, especially in environments with a significant number of users and devices. The other choices do not accurately represent the primary function of TACACS+, making option B the correct response.
