How often should keys and locks be audited?

• A. Monthly
• B. Weekly
• C. Quarterly
• D. Yearly

Answer: (A)

Regularly auditing keys and locks keeps control of who has access to classified areas and ensures all keys are accounted for. This process catches lost or stolen keys, unauthorized duplications, or changes in who should have access, and it does so in a timely way. Doing this monthly provides a solid balance: it keeps inventories current as people move roles or leave, allows quick revocation of access, and reduces risk without overburdening resources. Weekly checks are often more than necessary and can waste time, quarterly checks may allow too much time for discrepancies to slip by, and yearly checks miss changes that happen between audits. Monthly auditing maintains tight, accountable control while remaining practical.
