What are the requirements for making a combination change?

The requirements for making a combination change are based on the need for security and minimizing the risk of unauthorized access. Changing the combination at least every two years is a standard practice to ensure that even if someone has knowledge of the previous combination, access is denied after the change. Additionally, there are specific conditions under which a combination should be changed, such as when personnel with knowledge of the combination leave the organization or if there is a concern that the combination may have been compromised.

This approach emphasizes proactive measures in maintaining security. It also incorporates situational awareness and responsiveness to potential threats, ensuring that sensitive information remains protected even as personnel and circumstances evolve. While annual changes could theoretically enhance security, they are not always practical, and not changing at all can significantly elevate risk, especially if sensitive data or environments are involved.
