A propped door is an immediate security breach that must be corrected, documented, and reported without delay.

What information is typically required on a visitor badge issued at a secured facility?

Answer: Visitor's name, date, authorized area, and escort information

A visitor badge must identify the individual, limit access to authorized areas, and note any escort requirement so all personnel can verify compliance.

Under the principle of 'least privilege' in access control, employees are granted:

Answer: Only the minimum access necessary to perform their job duties

Least privilege limits access to only what is required for an employee's role, minimizing the potential damage from accidental or intentional misuse.

When a person's access credentials are revoked, the PSO checkpoint should be notified:

Answer: Immediately, so access is denied without delay

Immediate notification ensures that revoked credentials are denied at the point of entry without any window of unauthorized access.

Which of the following best describes a 'man-trap' (or airlock) in access control?

Answer: A two-door entry system where the first door must close before the second opens, preventing tailgating

A man-trap uses sequential door control to ensure only one person passes through at a time, physically preventing tailgating and piggybacking.
