Vulnerability of Wireless Networks to Interception
ArticleJIW32v21.pdf (1.174Mb)Abstract
This paper examines the vulnerability of wireless systems to interception, and provides
some simple steps that can be taken to improve security. A commercially available
computational electromagnetics software package was used to predict signal levels in
complex indoor and urban environments. The simulation results can be used to
determine the detection range of the network. Two basic scenarios are presented: (1)
indoor-to-outdoor propagation for a local area network operating in a two story
building, and (2) a wireless point-to-point link on an airbase. The simulations
illustrate some of the unique propagation conditions that occur inside of buildings and
in urban areas. This research has identified several possible system weaknesses and
suggested some simple, yet effective, methods of improving security.
