Defense Counterintelligence and Security Agency (DCSA) Security Professional Education Development (SPeD) Physical Security Certification Practice Exam

Using physical barriers in security is primarily focused on restricting and controlling access to sensitive areas. This is essential for protecting assets, information, and personnel from unauthorized access and potential threats. Physical barriers, such as fences, walls, and doors, create a defined perimeter and help delineate secure zones from public or less secure areas. By implementing these barriers, an organization can enforce access control measures and ensure that only authorized personnel can enter sensitive locations, thereby maintaining the integrity and security of those areas.

The other options do not align with the primary purpose of physical barriers in security. Allowing entry without authorization contradicts the fundamental goals of security. While enhancing employee morale can be an indirect benefit of a well-designed workspace, it is not a primary function of physical barriers. Similarly, while marketing opportunities can arise from certain architectural designs, they are not a reason for the implementation of security barriers, which are specifically meant to safeguard against threats rather than promote products or services.
