A company's building is mostly empty after 7 p.m., leaving only a cleaning crew on-site. Management wants a new physical control that will discourage intruders and be able to confront anyone who tries to enter without authorization, escort them out if necessary, and report the incident immediately. Which measure BEST meets these requirements?
Deploy additional networked video cameras with off-site monitoring
Add motion-activated lighting throughout the hallways
Install fixed bollards in front of the main entrance
Post uniformed security guards to patrol the facility during evening hours
Security guards provide both a psychological deterrent and an active response capability. A trained guard can verify identification, challenge suspicious individuals, physically intervene or escort them out, and contact law enforcement in real time. Bollards only stop vehicle ramming attacks, lighting improves visibility but cannot confront intruders, and video cameras merely record or alert-someone off-site still has to respond. Therefore, posting on-site security guards is the most effective single control for the stated needs.
