Mary has ensured that the external doors of her company’s facility uses nonhollow doors to provide the most protection. Two months after the building is finished being built she found out that an intruder entered the facility through this door. Which of the following most likely took place?

A.
The door frame provided the same amount of protection that the door did

B.
The hinges did not provide the same amount of protection that the door did

C.
The attacker entered the window right next to the door

D.
The door was made out of combustible material

Explanation:
The weakest portion of the structure, usually its doors and windows,
will likely be attacked first. With regard to doors, the weaknesses usually lie
within the frames, hinges, and door material. The bolts, frames, hinges, and
material that make up the door should all provide the same level of strength and
protection. For example, if a company implements a heavy, nonhollow steel door but
uses weak hinges that could be easily extracted, the company is just wasting money.
The attacker can just remove the hinges and remove this strong and heavy door.
