Which of the following is a best practice for physical security?

Reporting suspicious activity is a critical best practice for physical security because it helps maintain a safe environment and ensures that potential threats are addressed promptly. By being vigilant and proactive in reporting unusual or suspicious behaviors, individuals contribute to the overall security posture of the organization. This practice fosters a culture of awareness where everyone remains alert to security issues, thus potentially preventing theft, vandalism, or other security incidents before they escalate.

The focus on reporting also underscores the importance of communication and cooperation among employees and security personnel. When suspicious activities are reported, security teams can investigate and take appropriate action, which enhances the overall safety of the facility and the people within it.

In contrast, keeping entrances unlocked for convenience undermines security by providing easy access to unauthorized individuals. Ignoring unauthorized access attempts poses a significant risk as it allows potential threats to go unchecked. Only allowing pre-approved visitors, while important, is not sufficient on its own; it needs to be paired with active vigilance and reporting mechanisms to ensure that any breaches in security protocols are promptly dealt with.
