An office already uses electronic badge readers, CCTV cameras, and motion sensors at each entrance. Management wants an additional control that will actively deter intruders and provide an on-site response capability if a breach occurs. Which physical security measure BEST meets this requirement?
Deploy trained security guards to monitor the facility and respond to incidents
Add more motion-activated CCTV cameras with cloud recording
Install fixed steel bollards in front of the entrances
Upgrade badge readers to require multifactor authentication
Security guards add a human element that passive devices cannot: they deter unauthorized activity through visible presence, make real-time decisions, and physically intervene or call authorities during security incidents. Bollards, upgraded badge readers, and additional cameras enhance perimeter or detection controls but do not provide immediate human response.
