The basis for the handling and storage of classified data is the legal framework that governs its use, which includes classification markings and handling caveats. Proper handling and storage of classified data is critical to ensuring that it remains confidential and secure. The guidelines for handling and storing classified data include:
- Limiting access to only those who have a need-to-know
- Properly marking classified information with the appropriate classification level and handling caveats
- Using secure communication channels to transmit classified information
- Physically securing classified information in approved containers or rooms
- Regularly training personnel on proper handling and storage procedures
When determining whether a particular container or facility is appropriate for storing classified material, one general principle always holds true: the more sensitive the material being stored, the stricter the storage and protection methods must be. For example, Confidential information has stricter storage requirements than unclassified information, and Secret information must be protected at a higher level than Confidential information. All classified material must be stored in a secure room, a GSA-approved storage container, such as a cabinet or safe or a vault or modular vault, or a sensitive compartmented information facility (SCIF) .
