In a layered physical security strategy for a small office/home office environment, which of the following BEST describes the PRIMARY security purpose of installing a perimeter fence around the property?
To enhance the building's overall aesthetic appeal to clients
To reduce ambient noise from nearby traffic
To provide privacy screening for employees and visitors
To deter and delay unauthorized entry into the property
Perimeter fencing is a physical barrier that deters and delays intruders, making unauthorized entry more difficult and buying time for detection and response. Although fences may also improve privacy, aesthetics, or noise reduction, those are secondary benefits rather than the main security objective.
Deter and delay unauthorized entry: Correct. The fence establishes a controlled boundary that discourages and slows intruders.
Provide privacy screening: Incorrect. Privacy can be a benefit, but it is not the primary security purpose.
Reduce ambient noise: Incorrect. Noise abatement is unrelated to access control.
Enhance the property's aesthetic appeal: Incorrect. Appearance is incidental and not part of the security function.
