The Design and Evaluation of PPS
A PPS integrates people, procedures and equipment for: - answer The protection of
assets or facilities against theft, sabotage and other malevolent human attacks.
The design of an effective PPS requires a: - answer Methodical approach in which the
designer weighs the objectives of the PPS against available resources and then
evaluates the proposed design to determine how well it meets the objectives.
Security refers to: - answer Systems used to prevent or detect an attack by a
malevolent human adversary.
Theft, sabotage and other malevolent acts at a facility may be prevented in two ways: -
answer By deterring or defeating the adversary.
Deterring occurs by implementing measures that: - answer Are perceived by potential
adversaries as to difficult to defeat.
Examples of deterrents are: - answer Presence of security guards, adequate lighting at
night, posting of signs, and use of barriers such as bars on windows.
The design of an effective PPS includes: - answerThe determination of PPS objectives,
the initial design or characterization of a PPS, the evaluation of the design and a
redesign or refinement of the system.
In designing PPS, threat definition for the facility must be made and it must answer 3
questions: - answerWhat class of adversary is to be considered? What is the range of
the adversary's tactics? What are the adversary's capabilities?
Adversaries can be separated into 3 classes such as: - answerOutsiders, insiders and
outsiders working in collusion with insiders.
What are the range of tactics used by adversaries: - answerDeceit, force, stealth or any
combination of these.
Deceit is: - answerThe attempted defeat of a security system by using false
authorization and identification.
Force is: - answerThe overt, forcible attempt to overcome a security system.
Stealth is: - answerAny attempt to defeat the detection system and enter the facility
covertly.
,For any given facility there may be several threats such as: - answerA criminal outsider,
a disgruntled employee, competitors or some combination of the above.
The primary function of a PPS are: - answerDetection of an adversary, delay of that
adversary, and response by guard force (security personnel)
A PPS performs better if detection is: - answerAs far from the target as possible and
delays are near the target.
A PPS designer should be aware that detection without: - answerAssessment is not
detection.
A response force cannot respond unless: - answerIt receives a communication call for a
response.
Systems that are designed to protect high value critical assets generally require a: -
answerQuantitative analysis.
Systems protecting lower value assets may be analysed using: - answerQualitative
techniques.
A system is defined as: - answerAn integrated collection of components or elements
designed to achieve an objective according to a plan.
The designer of any system must have the system's: - answerUltimate objectives in
mind.
The ultimate objectives of a PPS is: - answerTo prevent the accomplishment of
malevolent covert or overt actions.
Other typical objectives of a PPS are to: - answerPrevent sabotage of critical
equipments, theft of assets or information from within the facility, and protection of
people.
A PPS must accomplish its objectives by either: - answerDeterrence or a combination of
detection, delay and response.
The PPS functions of detection and delay can be accomplished by: - answerThe use of
equipment and guards.
The key to a successful protection system is the integration of: - answerPeople,
procedures and equipment into a system that protects assets from malevolent
adversaries.
The purpose of a PPS is to prevent: - answerAn adversary from successful completion
of a malevolent action against a facility.
, In PPS functions it is important that Detection must be accomplished for: - answerDelay
to be effective.
For system to be effective there must be awareness that there is an attack (Detection)
and: - answerSlowing of adversary progress to the targets (Delay), thus allowing the
response force enough time to interrupt or stop the adversary (Response)
Detection is the: - answerDiscovery of adversary action.
The measures of effectiveness for the detection function are: - answerThe probability of
sensing adversary action and the time required for reporting and assessing the alarm.
Entry control refers to: - answerAllowing entry to authorized personnel and detecting the
attempted entry of unauthorized personnel and material.
The measures of effective of entry control are: - answerThroughput, false acceptance
rate and false rejection rate.
Throughput is defined as: - answerThe number of authorized personnel allowed access
per unit time, assuming that all personnel who attempt entry are authorized for
entrance.
False acceptance rate is the rate at which: - answerFalse identities or credentials are
allowed entry.
False rejection rate is the frequency of: - answerDenying access to authorized
personnel.
Once an alarm is initiated and reported: - answerAssessment begins.
An effective alarm assessment system provides 2 types of information associated with
detection: - answerWhether the alarm is a valid alarm or nuisance alarm and details
about the cause of the alarm-what, who, where and how many.
Delay is the: - answerSlowing down of adversary progress.
Delay can be accomplised by: - answerPersonnel, barriers, locks, and activated delays.
Response force personnel can be considered elements of delay if: - answerThey are in
fixed and well-protected positions.
The measure of delay effectiveness is: - answerThe time required by the adversary
(after detection) to bypass each delay element.
