CRL CRL Physical Security Assessment & Recommendations 1 — Questions and Answers
Question 1: When conducting a residential security survey, which door component should be inspected first for vulnerability?
- The strike plate and the depth and length of its mounting screws (Correct answer)
- The exterior paint condition and color visibility
- The door's aesthetic finish and hardware style
- The distance between the door and the nearest window
Correct answer: The strike plate and the depth and length of its mounting screws
Short or shallow strike plate screws are the most common weak point in residential door security and are frequently exploited in kick-in attacks.
Question 2: What is the purpose of a Door Reinforcement Kit (door armor) in a physical security assessment recommendation?
- To reinforce the door frame, hinge points, and strike plate against kick-in and pry attacks (Correct answer)
- To improve the door's insulation and energy efficiency rating
- To upgrade the exterior appearance of an entry door
- To allow smart lock installation without a professional locksmith
Correct answer: To reinforce the door frame, hinge points, and strike plate against kick-in and pry attacks
Door armor wraps the weakest structural points of an entry door system to resist forced entry techniques commonly used in burglaries.
Question 3: During a security assessment, a locksmith identifies that exterior hinges are exposed and unprotected on an inward-opening door. What is the correct recommendation?
- Install hinge bolts or non-removable pin hinges to prevent hinge removal attacks (Correct answer)
- Replace the entire door and frame with a steel unit
- Add a deadbolt on the hinge side of the door
- Relocate the door to swing outward to make hinges inaccessible from outside
Correct answer: Install hinge bolts or non-removable pin hinges to prevent hinge removal attacks
Exposed hinge pins on inward-opening doors can be driven out to remove the door; hinge bolts or security hinges neutralize this attack vector.
Question 4: Which ANSI/BHMA grade designation indicates the highest level of security and durability for commercial door hardware?
- Grade 1 (Correct answer)
- Grade 2
- Grade 3
- Grade 4
Correct answer: Grade 1
ANSI/BHMA Grade 1 hardware has passed the most rigorous cycle and force testing, making it the standard for high-security commercial applications.
Question 5: What does a locksmith look for when assessing a door frame for susceptibility to a pry attack?
- Gaps between the door stop and frame, thin or hollow frame material, and single-point latch engagement (Correct answer)
- The color contrast between the door and frame for visibility at night
- The number of hinges and their decorative style
- Whether the frame is painted or stained
Correct answer: Gaps between the door stop and frame, thin or hollow frame material, and single-point latch engagement
Pry attacks exploit weak frames, poor door stop reinforcement, and shallow latch engagement to force the door open without defeating the lock.
Question 6: When recommending a high-security padlock for a storage facility hasp, which feature is most important to specify?
- A hardened steel shackle with a short exposed arc and anti-cut/anti-drill body (Correct answer)
- A padlock with the widest shackle diameter available for easy chain threading
- A combination padlock to eliminate the need for key management
- A padlock with a brass body for corrosion resistance in outdoor environments
Correct answer: A hardened steel shackle with a short exposed arc and anti-cut/anti-drill body
A hardened short shackle minimizes the surface area available for bolt cutters or grinders, while a reinforced body resists drill and cut attacks.
