05- Physical Security QUIZ Flashcards
What is a mantrap?
A. A trusted security domain
B. A mechanism for logical accessing control
C. A double-door room used for physical access control
D. A device for fire suppression
Answer: C
A mantrap is a small room with two doors. The first door is locked; a person is identified and authenticated by a security guard, biometric system, smart card reader, or swipe card reader. Once the person is authenticated and access is authorized, the first door opens and allows the person into the mantrap. The first door locks and the person is trapped. The person must be authenticated again before the second door unlocks and allows him into the facility.
Which of the following is not a main component of CPTED? A. Natural access control B. Natural surveillance C. Territorial reinforcement D. Target hardening
Answer: D
Target hardening has to do with implementing locks, security guards, and proximity devices.
Which of the following is not a control category in a physical security program? A. Deterrence and delaying B. Response and detection C. Assessment and detection D. Delaying and lighting
Answer: D
The categories of controls that should make up any physical security program are deterrence, delaying, detection, assessment,
and response. Lighting is a control itself, not a category of controls.
Which of the following steps should be taken initially when a fire has been detected?
A. Turn off the HVAC system and activate fire door releases
B. Determine the type of fire
C. Instruct individuals to leave the building
D. Turn on the fire suppression system
Answer: C
Human life takes precedence. Although the other answers are important steps in this type of situation, the first step is to warn others and save as many lives as possible.
Which of the following is the best choice in choosing security guard for a physical access control
mechanism?
A. When discriminating judgment is required
B. When intrusion detection is needed
C. When the allotted security budget is low
D. When access controls are in place
Answer: A
Although many effective physical security mechanisms are on the market today, none can look at a situation, make a judgment about it, and decide what the next step should be. A security guard is employed when a company needs to have a countermeasure that can think and make decisions in different scenarios.
Which of the following problems are caused by humidity on electrical devices?
A. High humidity causes excess electricity whereas low humidity causes corrosion
B. High humidity causes corrosion whereas low humidity causes static electricity
C. High humidity causes power fluctuations whereas low humidity causes static electricity
D. High humidity causes corrosion whereas low humidity causes power fluctuations
Answer: B
High humidity can cause corrosion, and low humidity can cause excessive static electricity. Static electricity can short-out devices or cause loss of information.
What does positive pressurization pertaining to ventilation mean?
A. When a door opens, the air gets in
B. When a fire takes place, the power supply is disabled
C. When a fire takes place, the smoke is diverted to one room
D. When a door opens, the air goes out
Answer: D
Positive pressurization means that when someone opens a door, the air goes out, and outside air does not come in. If a facility were on fire and the doors were opened, positive pressure would cause the smoke to go out instead of being pushed back into
the building.
Which of the following means an access control has a fail-safe characteristic but not a
fail-secure characteristic?
A. It defaults to no access
B. It defaults to being unlocked
C. It defaults to being locked
D. It defaults to sounding a remote alarm instead of a local alarm
Answer: B
A fail-safe setting means that if a power disruption were to affect the automated locking system, the doors would default to
being unlocked. A fail-secure configuration means a door would default to being locked if there were any problems with the
power.
Which of the following is not considered as a delaying mechanism? A. Locks B. Defense-in-depth measures C. Warning signs D. Access controls
Answer: C
Every physical security program should have delaying mechanisms, which have the purpose of slowing down an intruder so security personnel can be alerted and arrive at the scene. A warning sign is a deterrence control, not a delaying control.
Which of the following is not a drawback to install intrusion detection and monitoring systems? A. Installation is expensive B. It cannot be penetrated C. It requires human response D. It is subjected to false alarms
Answer: B
Monitoring and intrusion detection systems are expensive, require someone to respond when they set off an alarm, and because of their level of sensitivity, can cause several false alarms. Like any other type of technology or device, they have their own vulnerabilities that can be exploited and penetrated.
