CSI Physical Security Surveys 3

Question 1

What is the purpose of a 'standoff distance' in physical security planning?

Accepted Answer

To establish a minimum distance between a potential explosive device and a protected structure

Answer

Standoff distance is a planned buffer that reduces blast effects on a structure by keeping potential explosive threats farther away.

Question 2

In a physical security survey, 'layers of protection' refers to:

Accepted Answer

A defense-in-depth strategy using multiple barriers and controls

Answer

Defense-in-depth layers multiple physical and procedural controls so that defeating one layer does not compromise the entire security system.

Question 3

Which of the following is the BEST indicator of a well-maintained physical security program during a survey?

Accepted Answer

Current, tested procedures with documented maintenance records

Answer

Documented, tested procedures and maintenance records demonstrate that the security program is actively managed and operationally effective.

Question 4

A mantrap (access control vestibule) is designed primarily to:

Accepted Answer

Prevent tailgating and control access one person at a time

Answer

A mantrap uses interlocked doors to ensure only one person passes through at a time, directly preventing tailgating into secured areas.

Question 5

During a survey, a surveyor should assess 'target hardening' measures. Target hardening BEST describes:

Accepted Answer

Physical modifications that make a target more difficult or less attractive to attack

Answer

Target hardening involves physical modifications—locks, barriers, reinforcement—that increase the difficulty and risk for a potential attacker.
