Abstract
Security in Wireless Local Area Networks has been of
concern lately, because of the increasing number and
variety of attacks in these networks. Increasing the
complexity of encryption and authentication mechanisms
used in such networks has been a de facto method of
ensuring security. However, a widespread adoption of
these solutions is still a distant reality because of
the inherent complexity of these security mechanisms.
Additionally, loopholes have been found in the solutions
suggested, which has triggered research and development
of yet newer mechanisms. The current state of solutions
warrants looking at newer solutions which are better
suited to the nuances of Wireless Local Area Networks
(WLANs). Intrusion detection system for monitoring and
countering security threats is a proven technology in
case of wired networks.
This white paper describes a new architecture for deploying
intrusion detection systems in WLANs as a security measure.
This architecture is also theoretically evaluated against
the currently known attacks in WLANs, which leads us
to believe that intrusion detection systems can succeed,
where the conventional security mechanisms have failed
in WLANs.
