Which of the following would not be considered a regular access control point?

The choice of a window as not being a regular access control point is based on the primary definitions of access control points. Access control points are typically defined as designated entry and exit locations that are monitored and managed to restrict access to authorized individuals. Doors, turnstiles, and gates are all common access points that are specifically designed to be controlled and secured.

A door serves as a main entry point, often equipped with locks and access control systems. Turnstiles are engineered to allow one person to pass at a time, enhancing security in areas that require controlled entry. Gates also serve a similar function, acting as barriers that can be managed to allow or deny access.

In contrast, windows are not typically designed or used as controlled access points. While they could potentially be used for entry, they do not generally provide the same level of security and controlled access as the other options listed, which are purposefully constructed with access control in mind. Therefore, they are commonly viewed as vulnerabilities in a security system rather than serious access control points.
