When must end-of-day security checks be conducted?

• A. At the end of the last working shift, unless operations run 24 hours per day.
• B. At the end of every shift, regardless of operations.
• C. Only when a security incident occurs.
• D. At the end of the first shift.

Answer: (A)

End-of-day checks are about closing out the day securely. They verify that every secure area is locked, devices and cabinets are secured, access logs and keys are accounted for, alarms are set, and sensitive materials are properly stored so the next day starts from a known secure state. The standard practice is to conduct this at the end of the last working shift, capturing the entire day’s activity in a single, clean handoff. If operations run 24 hours straight, there isn’t a natural day boundary to mark, so a separate end-of-day check isn’t required. End-of-day checks aren’t reserved for incidents; they’re routine to maintain ongoing protection. Conducting the check at the end of the first shift would leave the remainder of the day unverified and create gaps in security.
