Facilities belonging to any
of our military branches world-wide, offer
our enemies significant targets for both
real and political victories. Inflicting
even the smallest amount of damage on the
organized military forces of the United
States is viewed as a victory in certain
parts of the world. Because of this fact,
military assets must present superior physical
obstacles against hostile actions. Throwing
large numbers of personnel at the problem
is not feasible in the long term. Technology
provides a better and, going forward, a
more cost-efficient means of protecting
our military assets. Perimeter security
for these assets will continue to rely on
the defense-in-depth philosophy (previously
discussed under the nuclear heading) in
which concentric security barriers and buffer
zones both aid detection of a breach and
delay an attack. This allows time for a
sufficiently equipped response force to
react to the threat. The most effective
and reliable intrusion detection systems
use multiple technologies to increase the
probability of early detection under a broad
range of conditions.
