Fix Recommendation

*This requirement is specifically for vaults and secure rooms or open storage areas containing inspectable SIPRNet assets*:

The primary ingress/egress door must be equipped with a proper combination lock that is installed properly and is being used. Door must be equipped with a built-in GSA-approved combination lock meeting Federal Specification FF-L-2740, such as the X07, X09, and Kaba Mas X-10 locks.

NOTE: The use of automated entry control systems (AECS) is encouraged to control access to secure room space during working hours; however, electrically actuated locks (e.g., cypher and magnetic access card locks) do not afford by themselves the required degree of protection for classified information and must not be used as a substitute for the combination locks meeting Federal Specification FF-L-2740.
