Wireless Forensic: A New Radio Frequency Based Locating System

Abstract

Wireless networks are more prevalent today since they enhance the user flexibility and mobility when browsing online. However, those advantages come at a price. Wireless networks do not provide the same security features as its wired counterpart. An unprotected wireless network can be easily served as a stepping-stone in attacks through such as Warchalking. Due to the nature of wireless networks, it is very difficult to trace back to the intruder. The three current location tracking solutions: Closest Access Point, Triangulation, and Radio Frequency Fingerprinting have their own limitations in tracing wireless intruders. In this paper, we propose a more precise location tracking system - Multiple Grids System - that overcomes the limitations of the existing solutions. This new approach uses a modified wireless grid to track wireless hackers in long distance or short range at different floors of the same building. Our proposed multiple grids system can be effectively applied to detect, track and prevent wireless intruders. We also substantially present that our system can be collaborated with multiple locating applications.
