Question 650
An enterprise access-control incident describes: A security engineer claims placing a network device under TACACS+ proves privileged commands are encrypted end to end across every intermediate network segment. What is the most suitable solution within these constraints?
Explanation
Correct Answer
Protect the device-to-ISE management path with supported additional network security and accurately document TACACS+ transport properties. This is appropriate because tACACS+ does not by itself replace the need for a trusted protected management path; authentication and authorization are distinct from full transport protection. It should be verified by this evidence: Management traffic follows the approved secured route and a network-path audit confirms the intended additional safeguards.
Incorrect Answers
Protect the device-to-ISE management path with supported additional network security and accurately document TACACS+ transport properties. The offered choice instead concerns a different principle: Maintain protocol-specific AAA network port and service documentation. Those technical conditions are not interchangeable.
Protect the device-to-ISE management path with supported additional network security and accurately document TACACS+ transport properties. The offered choice instead concerns a different principle: Use stage-specific posture error classification instead of broad credential resets. Those technical conditions are not interchangeable.
Protect the device-to-ISE management path with supported additional network security and accurately document TACACS+ transport properties. The offered choice instead concerns a different principle: Synchronize the device-specific TACACS+ shared secret and confirm the correct source address maps to the intended NAD entry. Those technical conditions are not interchangeable.
