Explanation: According to the Shared Assessments Certified Third Party Risk Professional (CTPRP) Study Guide, physical security compliance is the process of ensuring that the physical assets and personnel of an organization are protected from unauthorized access, theft, damage, or harm1. Physical security compliance can be achieved by implementing various measures, such as locks, alarms, cameras, guards, fences, badges, etc. However, these measures need to be regularly monitored, tested, and verified to ensure their effectiveness and alignment with the defined standards and policies2. Therefore, maintaining a standardized schedule for confirming controls to defined standards demonstrates a greater maturity of physical security compliance, as it indicates a proactive and consistent approach to assessing and improving the physical security posture of an organization3.
The other options do not reflect a high level of physical security compliance maturity, as they either rely on reactive or ad hoc methods, or lack sufficient verification and validation mechanisms. Leveraging periodic reporting to schedule facility inspections based on reported events may indicate a lack of preventive and predictive measures, as well as a dependency on external or internal incidents to trigger the inspections. Providing a checklist for self-assessment may indicate a lack of independent and objective evaluation, as well as a potential for bias or error in the self-assessment process. Conducting unannounced checks on an ad hoc basis may indicate a lack of planning and coordination, as well as a potential for disruption or inconsistency in the checks.
