RSSAT: A Wireless Intrusion Detection System Based on Received Signal Strength Acceptance Test

Intrusion detection in wireless networks has been a challenging researchproblem in network security for more than half a century. This paper presents anovel intrusion detection method based on Received Signal Strength AcceptanceTest (RSSAT) to improve the IDS capabilities in anomaly-based Host-basedIntrusion Detection Systems (HIDS). The new system can identify suspiciousbehaviors detecting anomalies in the received signal strength from the access points.Several scenarios are implemented in Omnet++ environment to evaluate theperformance of the proposed scheme. A test criterion is used to improve accuracy indetecting forged signal powers and at the same time to reduce number of the falsepositives i.e. number of false attack alerts resulted from the legitimate signalpowers.
