Which of the following is NOT a reason for changing lock combinations?

• A. A person knowing the combination no longer requires access
• B. The renewable one-year access review
• C. The PSO considers a change necessary
• D. The lock is taken out of service

Answer: (B)

The selection of B as the answer highlights an important aspect of access control and security management. A renewable one-year access review primarily serves as a routine evaluation of access privileges and security measures rather than a direct trigger for changing lock combinations.

Conducting these annual reviews is essential for ensuring that individuals with access still require it based on their current roles and responsibilities. However, the review itself doesn’t dictate that a lock combination needs to be changed. Lock combinations are typically altered when there is a more immediate need, such as personnel changes, perceived security threats, or the discretion of the Personnel Security Officer (PSO).

In contrast, the other reasons provided for changing lock combinations indicate specific situations that necessitate action. If a person who had access is no longer authorized, or if the PSO believes a change is essential for maintaining security, these circumstances warrant updating the lock combination. Additionally, if a lock is decommissioned or taken out of service, there would be no need for its combination, reinforcing that option as a valid reason for change.
