Which of the following physical security controls would be the most effective in preventing an attacker from driving a vehicle through the glass doors at the front of the organization’s headquarters?

c. Bollards
Bollards are a physical security control that is designed to prevent a vehicle-ramming attack. Bollards are typically designed as a sturdy, short, vertical post.

Mantraps are designed to prevent individuals from tailgating into the building.
Security guards and intrusion alarms could detect this from occurring, but not truly prevent them.
You work for Dion Training as a physical security manager. You are concerned that the physical security at the entrance to the company is not sufficient. To increase your security, you are determined to prevent piggybacking. What technique should you implement first?

The public library has had a recent issue with their laptops being stolen from their computer lab. Since this is a public library, it is not a high security area and is fully accessible by patrons during the day. What is the best way to prevent the theft of the laptops?
a. Motion Sensors
b. Mobile Device Management
c. Cable Locks
d. CCTV
c. Cable Locks
Cable locks are the best solution, as it will allow the laptops to be physically connected to the desks in the computer lab and can prevent theft.
CCTV is a deterrent or detective control, but will require someone monitoring it to detect the theft.
Mobile device management is focused on tablets or phones, not laptops.
Motion sensors are not useful during the library’s open hours, since authorized patrons are allowed into the lab during the day. Therefore, if a laptop is being stolen during the day, motion senors will be useless to stop them.
