• Requirement

    Maintain audit logs of physical access.

  • Discussion

    Organizations have flexibility in the types of audit logs employed. Audit logs can be procedural (e.g., written log of individuals accessing the facility), automated (e.g., capturing ID provided by a PIV card), or some combination thereof. Physical access points can include facility access points, interior access points to systems or system components requiring supplemental access controls, or both. System components (e.g., workstations, notebook computers) may be in areas designated as publicly accessible with organizations safeguarding access to such devices.

  • Further Discussion

    Make sure you have a record of who accesses your facility (e.g., office, plant, factory). You can do this in writing by having employees and visitors sign in and sign out or by electronic means such as badge readers. Whatever means you use, you need to retain the access records for the time period that your company has defined.


    You and your coworkers like to have friends and family join you for lunch at the office on Fridays. Your small company has just signed a contract with the DoD, however, and you now need to document who enters and leaves your facility. You work with the reception staff to ensure that all non-employees sign in at the reception area and sign out when they leave [a]. You retain those paper sign-in sheets in a locked filing cabinet for one year. Employees receive badges or key cards that enable tracking and logging access to company facilities.

    Potential Assessment Considerations

    • Are logs of physical access to sensitive areas (both authorized access and visitor access) maintained per retention requirements [a]?
    • Are visitor access records retained for as long as required [a]?
