Preliminary Physical Security Considerations. Security fences
will not stop a determined intruder. To be effective, such barriers must be
augmented by security force personnel and other means of protection,
detection, delay, and assessment. Security fences are used primarily to:
define the perimeter of a restricted area.
provide a physical and psychological deterrent to entry
while serving notice that entry is not freely permitted.
prevent accidental entry.
optimize security force operations.
enhance detection and apprehension of intruders.
channel and control the flow of personnel and vehicles
through designated portals.
Keep these factors in mind while proceeding with the security
Prior to making decisions to employ security fencing, perform a
thorough risk and threat analysis to determine the degree of physical security
required. As indicated in Chapter 2 of Chief of Naval Operations Instruction
(OPNAVINST) 5530.14B, extensive and costly security measures may be justified
in certain cases to protect certain assets of security interest; however,
ultimately the commanding officer of an activity is responsible for complying
with established security requirements while at the same time working to
achieve economy. To achieve this objective, higher echelon security
requirements must be clearly understood. Additionally, evaluate the relative
criticality and vulnerability of the security interest in relation to a
ranking of potential threats, and calculate the specific level of security to
ensure the best possible protection for that threat level in a cost-effective
manner. Only after the above preliminary factors are addressed can a proper
design be initiated. See MIL-HDBK-1013/1, Design Guidelines for Physical
Security of Fixed Land-Based Facilities, for guidance and more detailed
procedures which may be helpful in the decision process.
It is imperative that security fencing requirements for restricted
areas be evaluated on a case-by-case basis. Installing large quantities of
security fencing around an entire outer perimeter may not be practical or
cost-effective, and may not improve security, particularly in remote and
unpopulated areas. Consider the following:
