What phrase must be on the front of a GSA-approved security container?

The phrase that must be on the front of a GSA-approved security container is "General Services Administration-Approved Security Container." This designation signifies that the container meets specific security standards set by the General Services Administration, which governs the storage of classified materials and ensures that the container provides adequate protection against unauthorized access.

Using this phrase helps ensure that all personnel are aware of the security standards associated with the container. It communicates that the container itself has undergone evaluation and has been deemed suitable for the secure storage of sensitive materials, thus supporting the overall security protocols in place for handling classified information. This standardization is crucial in maintaining compliance with government regulations and ensuring the safety and security of sensitive data.

The other options, while they may pertain to security practices or emphasize caution, do not specifically indicate the GSA approval status of the security container. This distinction is important for regulatory compliance and organizational security measures.
