Question 150
A facilities contractor needs occasional physical access to a locked wiring closet. Security policy requires preventing unauthorized changes to production switches. Which program control is most relevant?
Explanation
Correct Answer
Physical access controls, visitor management and audit logs reduce the chance that unauthorized people can reach cable plant and network devices. Contractor permissions should be explicit and time bounded.
Incorrect Answers
Shared administrative accounts erase individual accountability and do not verify that a physical visitor is approved for a wiring closet. Access must be controlled and traceable.
Making the entry code public undermines the security boundary and allows anyone viewing guest information to enter sensitive infrastructure areas.
Port security protects certain Layer 2 attachment risks but does not authorize physical contractor access. Disabling it broadly weakens endpoint control.
