vid 2 Flashcards
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 IS NO IMPENETRABLE BARRIER
The possibility of surreptitious entry is the greatest hazard from the standpoint of counterintelligence security because it is usually difficult to determine that the information has been compromised. No action is taken to neutralize the act of espionage because surreptitious entry is not usually detected.
SURREPTITIOUS VERSUS NON-SURREPTITIOUS ENTRY
Acquisition of information is the ultimate results, and the means and form in which the information is obtained.
ENEMY AGENTS 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 installations.
BARRIER
these are offered by nature which could obstruct or delay the passageway of potential intruders.
NATURAL
these are structural constructions like fences, walls, floors, roofs, grills, bars, roadblocks, or other physical means to deter or impede penetration.
MAN-MADE
include mountains, cliffs, canyons, ravines, seas, marshes, deserts, or terrain difficult to traverse.
NATURAL BARRIERS
are those features constructed by man regardless of their original intent that tend to delay the intruder. Examples: walls, ceilings, door, and fences etc.
STRUCTURAL BARRIER
include guards. charges of quarter’s office and shop workers, who stand between the intruder and the matter to be protected.
HUMAN BARRIERS
are usually shepherd dogs trained for and used as guards, aside from dogs there are other animals that can be used also, like a goose.
ANIMAL BARRIER
are usually electrical and electronic devices that could assist security personnel in detecting intrusions. Examples; protected lighting, and anti - intrusion devices.
ENERGY BARRIER
is a system designed to impede unauthorized external act such as simple intrusion to armed attack. Used of simple physical barriers such as doors and windows with ordinary locks.
MINIMUM SECURITY
is a system designed to impede and detect some unauthorized external activity such as on small retail store, storage warehouses.
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. Large manufacturing plants, large bonded warehouses and mega malls are suited for medium security level.
MEDIUM SECURITY
is designed to impede, detect and assess most unauthorized external and internal activities of certain prisons, defense contractors, pharmaceutical companies and sophisticated electronic manufacturers.
HIGH LEVEL SECURITY
is designed to impede, detect and assess most unauthorized external and internal activities of certain highly sensitive establishments and places
MAXIMUM SECURITY
A medium or structures, which define the physical limits of an installation or area to restrict or impede access thereto. Any physical barrier used to supplement the protection of an inside perimeter.
PERIMETER BARRIER
A line protection adjacent to protected area and passing through points of possible entry into the area. Ex: Doors, windows, tunnels
INSIDE PERIMETER
A line protection surrounding but somewhat removed from the protected area, such as fence
OUTSIDE PERIMETER
Kinds of Perimeter barriers
INSIDE PERIMETER
OUTSIDE PERIMETER
includes all perimeter barriers such as fences, bodies of water, gates, etc.
1st line of defense
includes walls, doors, windows, roof, etc.
2nd line of defense
includes those internal control measures specifically protective cabinets.
3rd line of defense
is a metallic container used for the safekeeping of documents or small items in an office or installations.It can be classified as either robbery or burglary resistance depending upon the use and need.
SAFE
the weight of the SAFE must be at least_____ and its body should be __ inch thick steel
750 lbs , 1 inch thick
this is a heavily constructed fire and burglar resistance container usually a part of the building structure used to keep and protect cash, documents and negotiable documents. Vaults are bigger than safe but smaller than a security file room.
VAULT
The vault door should be made of steel at least ___inches in thickness.
6
The vault walls, ceiling, floor reinforce concrete at least ___ inches in thickness.
12
The vault must be resistive up to ___ hours.
6
it is a cubicle in a building constructed a little higher than a vault but bigger size to accommodate limited people to work on the records inside.
FILE ROOM
The file room should at most be ______
high
12 FEET
File room must have a watertight door and at least fire proof for ___________.
1 HOUR
When not in active use and controlled by guards, gates and doors in the perimeter should be locked and frequently inspected by guards. Locks should be changed from time to time.
GATES AND DOORS
should also be guarded or grills should be installed so as not to be used by intruders.
WINDOWS AND SIMILAR OPENINGS
These provide access to areas within the perimeter barrier, and should be locked or guarded.
SIDEWALK ELEVATORS
Sewers, air intakes, exhaust tunnels and other utility openings which penetrate the barrier, and which have cross sectional area of ninety-six (96) square inches or more should be protected by bars, grills, water-filled traps or other structural means providing equivalent protection to that portion of the perimeter barrier.
UTILITIES OPENINGS
An unobstructed area or a “clear zone” should be maintained on both sides of the perimeter barrier.
CLEAR ZONES
are independent structures designed to physical and visual access between outside areas.
FENCES
The minimum height of fence should be at least _______excluding top guard.
7 FEET
made of solid material in such a way that visual access through the fence structure is denied. Solid fences are constructed with heavy materials such as bricks, stone and concrete, and usually extended down into the ground to a point of view below the front line.
SOLID FENCE
is constructed in such a manner that visual access is permitted such as wire fence, through the fence structure. It is designed purely to control physical access between two areas.
FULL VIEW FENCE
A river, lake, marsh, cataract, sea, pond, or any bodies of water forming a part of the wall, building or fencing should never be considered adequate natural perimeter barrier.
BODIES OF WATER
Masonry walls as perimeter barrier should have the same height as the chain-link and surmounted by the barbed wire top guard. If the height of masonry is less than the prescribed, additional chain-link as “topping” is placed to attain the minimum height requirement.
BUILDING WALLS
Barbed wire fencing should not be less than _______high excluding top guard.
7 FEET
Barbed wire fencing must be firmly affixed to posts not more than ______.
6 FEET
is commercially manufactured wired coil of high strength steel barbed wire clipper together at intervals to form a cylinder.
CONCERTINA FENCE
A clear zone of _________ or more is desirable between the barrier and exterior structure and natural covers_which may provide concealment or assistance to a person seeking unauthorized entry.
20 FEET
Whenever possible a clear zone of at least _______ should be maintained between the barrier and the structure within the perimeter.
50 FEET
An additional overhang or barbed wire placed on vertical perimeter fences facing upward and outward with a 45-degree angle with three to four strands of barbed wires spaced 6-inches apart and must be stalled on the supporting arms.
TOP GUARD
Normally provided at the main perimeter and entrance to secure areas located out of doors and manned by guards on a full-time basis.
GUARD CONTROL STATIONS
House-like structures above the perimeter barriers.
TOWERS OR GUARD TOWER
This are employed in augmenting the existing perimeter security or perimeter barriers of a certain establishment.
PERIMETER GUARDS
These security guards are assigned in a particular place of the compound to guard and watch the area surrounding.
FIXED POST
In this system, the security guard is required to walk and go around regularly around the company premises.
