What does the two-person concept in facility access control require?

The two-person concept in facility access control requires that two individuals be present in a defined area. This principle is designed to enhance security by ensuring that potentially sensitive or dangerous activities cannot be conducted by a single person alone, thereby reducing the risk of malicious actions, unauthorized access, or accidents.

This approach is particularly critical in high-security environments where the presence of an individual alone could lead to compromises in security or safety. The presence of two individuals serves as a check and balance system, ensuring that actions are transparent and that decisions are made collaboratively.

In the context of facility security, this concept helps to mitigate risks by ensuring accountability and oversight of access control measures. The requirement for two individuals also deters unauthorized access since both must agree to permit entrance into restricted areas, thereby creating a stronger security posture.
