Abstract: IEEE 802.11 networks are subject to MAC-spoof attacks. With this an attacker can steal the identity of a legitimate station, even access points, enabling him to take full control over network basic mechanisms and possibly access restricted resources. In this paper, we propose a new method to detect this, based on signal power monitoring. The main contribution of our work is the introduction of a median filter that enables the detection of the attack by looking at the variance of the signal power. We take into account two types of references for the samples: 1) time; 2) number of frames, and compare their detection capabilities. Our experimental results show that the spoofing attack is successfully detected with both types of references. Moreover the median filter helps to reject false positives.
