What physical security measure must the site security manager implement?

The site security manager must implement access control measures according to ICD 705 because this guideline outlines specific physical security standards that are necessary for protecting classified information and assets. ICD 705 provides requirements for securing sensitive areas such as facilities that handle classified materials or information, ensuring that only authorized personnel can gain access to these high-security locations.

By adhering to these measures, the site security manager reinforces the integrity and confidentiality of the information being protected, thereby minimizing the risk of unauthorized access or potential security breaches. Access control measures can include features such as security clearance checks, badge entry systems, monitoring of entry and exit points, and physical barriers to enhance the overall security of the facility.

While regular training for employees, emergency evacuation drills, and data encryption are important security practices, they do not specifically address the fundamental need for controlled physical access to sensitive areas, as delineated by ICD 705. Therefore, implementing access control measures is a prioritized action that aligns with the broader requirements for protecting sensitive information.
