What level of classification should safe combinations be safeguarded at?

Safe combinations should be safeguarded at the highest level of classification because they are considered sensitive information that, if compromised, could lead to unauthorized access to secure areas or valuable assets. The rationale behind this is centered on the safeguarding of assets that may contain classified or sensitive material. Ensuring that safe combinations are handled with the utmost security reflects the importance of protecting not only the physical combinations but also the integrity of whatever is stored within those safes. This aligns with best practices in security and risk management, which dictate that access to critical information should be restricted to those who are adequately cleared and trained to handle it, thus minimizing potential risks associated with its compromise.
