What action is recommended to prevent unauthorized site access within physical facilities?

Regularly checking access logs is a proactive measure that enhances security by ensuring that all entries and exits are monitored and documented. This practice helps identify any unauthorized access attempts or patterns that could indicate a potential security breach. Maintaining accurate logs allows security personnel to trace who accessed the facility, when they did so, and to investigate any anomalies. By analyzing this data, the organization can respond more effectively to potential threats and strengthen overall security protocols.

In contrast, simply allowing anyone with a badge access does not account for the possibility of badges being misplaced or misused. Posting access restrictions may raise awareness but doesn't actively monitor or enforce compliance with security measures.
