Is an access control system required if a SCIF has a high security lock?

In the context of Sensitive Compartmented Information Facilities (SCIFs), the security measures in place are designed to protect classified information from unauthorized access. While a high-security lock is an important component of physical security, it is not sufficient on its own to meet the requirements for protecting sensitive information.

An access control system includes methods of granting or denying access to individuals based on their security clearance and need-to-know, which adds an additional layer of defense beyond just physical barriers like locks. In a SCIF, access control systems are critical for ensuring that only authorized personnel can enter and that their access can be monitored and logged.

While a SCIF may have a high-security lock, this alone does not fulfill the comprehensive security requirements established by regulations governing SCIF operations. Therefore, an access control system is indeed required to ensure compliance with these regulations and to effectively manage and mitigate security risks associated with classified information.
