A security analyst is reviewing the physical security controls for a new data center. To protect the main entrance from vehicle-based threats, the analyst recommends installing bollards. Which type of security control do bollards primarily represent?
Bollards are a type of physical security control designed to prevent an incident from occurring. In this case, they physically block unauthorized vehicles from ramming the building's entrance, making them a preventive control. Detective controls (e.g., alarms, surveillance), corrective controls (e.g., disaster recovery plans), and compensating controls (e.g., using a different security measure when the primary one fails) serve different purposes.
