Abstract

Wireless IDS architectural metrics are used to compare the intended scope, architecture of wireless IDS, and how they match the deployment architecture. These metrics can be used to evaluate the architectural efficiency of a wireless IDS and can help in designing efficient wireless IDS. Wireless IDS analyze wireless specific traffic including scanning for external users trying to connect to the network through access points and play important role in security to wireless network. Design of wireless IDS is a difficult task as wireless technology is advancing every day, Architectural metrics can play an important role in the design of wireless IDS by measuring the areas concern with the architecture of a wireless IDS. In this paper we describe a set of architectural metrics that are relevant to wireless IDS. A 201C;scorecard201D; containing the set of values is used as the centerpiece of testing and evaluating a wireless IDS. Evaluation of a wireless IDS can be done by assigning score to various architectural metrics concern with wireless IDS. We apply our architectural metrics scorecard based evaluation approach to three popular wireless IDS Snort-wireless, AirDefense Guard, and Kismet. Finally we discuss the results and the opportunities for further work in this area.
