What are some examples of physical security measures?

The selected answer is correct because it includes examples that directly relate to physical security measures used to protect facilities, assets, and personnel. Access control systems are fundamental to physical security as they regulate who can enter certain areas within a facility, ensuring that only authorized individuals have access. Surveillance cameras enhance security by monitoring activities in and around the facility, acting as both a deterrent and a means of evidence collection. Security personnel are essential for actively managing and responding to security incidents, providing a human presence that can address threats in real-time.

The other options present elements that, while important in their respective areas, do not directly pertain to physical security measures. Employee training programs and team meetings, for instance, focus on workforce development and communication rather than security hardware or practices. Financial audits and risk assessments are crucial for identifying vulnerabilities and ensuring compliance but are more aligned with operational or financial security rather than physical protection. Marketing strategies and public relations campaigns pertain to how an organization promotes itself and interacts with the public, which again is unrelated to physical security. Thus, option A stands out as the only choice that encompasses measures directly aimed at securing physical environments.
