Part 2 Flashcards
✓
This is the broadest type of security.
✓
As a major division of industrial security, it can be defined as those measures taken
to prevent physical access or entry to an installation or area by unauthorized
personnel.
✓
covers other types of security to protect equipment, documents,
facilities and materials against theft, damage, sabotage or espionage. It also
encompasses protection of personnel from any criminal act.
Physical Security
✓
In order that barrier could prevent unauthorized access and serve its purpose very
well, there should be an integration of all barriers adopted in the installation.
Defense in depth means barrier after barrier
✓
Since each installation is different, each will have different problems to overcome.
The security procedures will not be adequate for all installations.
Each installation is different
✓
For the unfriendly government or organization, they are willing to devote enough
time, money, personnel, materials, and imagination in passing barriers. So physical
security attempts to build defense by using a certain barrier.
There’s no impenetrable barrier
✓
The possibility of surreptitious entry is the greatest hazard from the standpoint of
counter- intelligence security because it is usually difficult to determine that the
information has been compromised.
✓
No action is taken to neutralize the act of espionage; surreptitious entry is not
usually detected.
Surreptitious versus non-surreptitious entry
✓
Acquisition of information is the ultimate result, and the means and form in which
the information is obtained.
Enemy Agent must access
Refers to any physical structure whether natural or man-made capable of
restricting, deterring, delaying or preventing illegal and unauthorized access to an
installation
Barrier
these are offered by nature which could obstruct or delay the
passageway of potential intruders.
Nature
these are structural constructions like fences, walls, floors, roofs,
grills, bars,roadblocks, or other physical means to deter or impede penetration.
Manmade
include mountains, cliffs, canyons, ravines, seas, marshes,
deserts, or terrain difficult to traverse.
Natural barrier
are those features constructed by man regardless of their
original intent that tend to delay the intruder. Examples: walls, ceilings, doors, and
fences etc.
Structural barriers
includes guards, & charges of quarter’s office and shop
workers,
who stand between the intruder and the matter to be
protected. (Considered as the weakest link because they can be easily tempted.)
Human barriers
usually shepherd dogs trained for use as guards, aside from
dogs there are other animals that can be used also, like a goose. (Dogs are usually
used as guards as animal barriers because they have a sense of smell 10, 000, 000
times more than humans, but their weakness is their sense of identity unlike
humans.)
Animal barriers
are usually electrical and electronic devices that could assist
security personnel in detecting intrusions. Examples; protected lighting, and antiintrusion devices.
Energy barriers
is a system designed to impede unauthorized external acts
such as simple intrusion to armed attack.
-
Use of simple physical barriers such as doors and windows with ordinary
locks.
Minimum barrier
is a system designed to impede and detect some
unauthorized external activity such as on small retail store, storage warehouses.
✓
Basic local alarm systems
✓
Simple security lighting
✓
Basic security physical barrier
✓
High security locks
Low level security
is designed to impede, detect and assess most external activity
and some unauthorized internal activity that range from simple shoplifting to
conspiracy to commit sabotage.
