Which physical security control consists of sturdy vertical posts installed in front of entrances or vulnerable structures to block unauthorized vehicle access and mitigate vehicle-ramming attacks?
Door lock
Access control vestibule
Badge reader
Bollards
Bollards are short, robust vertical posts that form a barrier strong enough to stop or deter vehicles, protecting buildings and pedestrians from ram-raiding or accidental collisions. An access-control vestibule safeguards door entry, a badge reader authenticates users, and a door lock secures an individual doorway-none of these physically prevent vehicles from entering a protected space.
