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
