Many enterprises deploy 802.11 wireless networks for mission-critical operations; these networks must be protected for dependable access. This paper introduces the MAP project, which includes a scalable 802.11 measurement system that can provide continuous monitoring of wireless traffic to quickly identify threats and attacks. We discuss the MAP system(More)
Unauthorized 802.11 wireless access points (APs), or rogue APs, such as those brought into a corporate campus by employees, pose a security threat as they may be poorly managed or insufficiently secured. An attacker in the vicinity may easily get onto the internal network through a rogue AP, bypassing all perimeter security measures. Existing detection(More)
— The shared medium of 802.11 wireless networks means that they are susceptible to many MAC-layer attacks, such as frame spoofing, denial of service, and greedy misbehavior. To detect such attacks it is necessary to monitor the wireless channel itself and examine the timing and content of the 802.11 frames. Wireless " sniffing " is challenging: sniffers may(More)
