Discussion [NIST SP 800-171 R2]
Individuals with permanent physical access authorization credentials are not considered visitors. Audit logs can be used to monitor visitor activity.
Do not allow visitors, even those people you know well, to walk around your facility without an escort. Make sure that all non-employees wear special visitor badges and/or are escorted by an employee at all times while on the property.
