Which protection level applies to facilities such as Air Force accounting and finance vault areas?

The protection level for facilities like Air Force accounting and finance vault areas is classified as Level 4. This designation is due to the sensitive nature of the information and financial resources housed within these facilities. Protection Level 4 is indicated for facilities that require a higher degree of security due to the potential for serious consequences if the information or assets are compromised. This typically includes safeguarding classified information and managing significant threats to national security.

In the context of protection levels, Level 4 ensures that stringent security measures are in place, such as robust access controls, surveillance systems, and physical barriers, to prevent unauthorized access and protect the integrity of the operations conducted within those facilities.
