What are physical perimeter controls, and why are they important in asset protection?

• A. Password policies for internal systems
• B. Data encryption methods for storage
• C. Barriers and devices like fences, gates, bollards, and access points that deter, detect, and delay unauthorized entry, protecting assets and people.
• D. Network segmentation

Answer: (C)

Physical perimeter controls are the barriers and devices that create a boundary around a facility and work to deter, detect, and delay unauthorized entry. Fences, gates, bollards, and controlled access points are classic examples, often supported by lighting and surveillance as part of the boundary. They are essential because they form the first line of protection for people and assets. By deterring attempts, slowing intruders, and triggering alarms or alerts, these controls give security personnel time to respond, reduce the likelihood of theft or damage, and prevent unauthorized access to sensitive areas. They also provide a visible deterrent and contribute to overall safety and regulatory requirements, fitting into a layered, defense-in-depth approach with other measures like access control systems and monitoring. These physical measures differ from IT protections (such as password policies, data encryption, or network segmentation), which focus on safeguarding information rather than guarding space and people.
