Discussion [NIST SP 800-171 R2]
Access can be limited by physically controlling system media and secure storage areas. Physically controlling system media includes conducting inventories, ensuring procedures are in place to allow individuals to check out and return system media to the media library, and maintaining accountability for all stored media. Secure storage includes a locked drawer, desk, or cabinet, or a controlled media library.

Further Discussion
Limit physical access to CUI to people permitted to access CUI. Use locked or controlled storage areas and limit access to only those allowed to access CUI. Keep track of who accesses physical CUI in an audit log.
