Mike is responsible for physical security at his organization. He is particularly worried about an attacker driving a vehicle into the building. What would provide the best protection against this risk?

The correct answer is bollards. These are large objects, often made of concrete or similar material, designed specifically to prevent a vehicle from getting past them. Most gates can be breached with a vehicle. A security guard is a good idea, but they would not be able to stop a vehicle from ramming the building. Security cameras will provide evidence of a crime that was committed but won’t prevent the crime.
