SECTION D-4: 
LEVEL OF PROTECTION 
D-4.1 
Introduction.  Some material in this section is taken 
from Army TM 5-583-1.  Analysts familiar with this document may 
prefer to use it to develop security glazing design criteria. 
Levels of protection refer to the degree to which an 
asset is protected against the threat based on its value to its 
user.  A high level of protection corresponds to a low 
probability that an asset will be compromised and attacked.  For 
some tactics, level of protection refers to the amount of damage 
a facility or asset would be allowed to sustain in the event of 
an attack.  A low amount of allowed damage equates to a high 
level of protection.  For other tactics, level of protection 
refers to the probability that an aggressor will be defeated 
before the asset is compromised.  A high probability of defeat 
equates to a high level of protection.  There are one or more 
levels of protection (very high, high, medium, or low) for each 
of the five tactics, as shown in Table D-31. 
The levels of protection are described in detail for 
each tactic in subsequent sections where they are used as a basis 
of design.  Levels of protection apply to all threat severity 
levels for each tactic. 
D-4.2 
Level of Protection Procedure.  Figure D-19 presents 
the process chart and Figure D-20 provides a description for the 
level of protection procedure.  They furnish structures and 
explanations for determining the level protection for each tactic 
for each asset. 
D-4.2.1 
Required Information.  The following information is 
required for the level of protection procedure: 
a) General knowledge of appropriate levels of 
protection for assets 
b) Worksheets (see Appendix B):
