An organization wants to prevent unauthorized vehicles from accessing the parking area adjacent to their building, particularly to prevent vehicles from being driven into the building. What physical security measure should they implement to mitigate this threat?
Erect fencing around the perimeter of the building
Deploy security guards at the parking entrances
Install bollards around vulnerable areas
Set up video surveillance to monitor the parking area
Bollards are robust vertical posts that can stop vehicles from entering restricted areas, effectively preventing ramming attacks. While fencing can deter unauthorized access, it may not withstand the impact of a vehicle. Security guards and video surveillance can detect and monitor but cannot physically stop a vehicle from breaching the perimeter.
