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 rogue access points (APs), such as those brought into a corporate campus by employees, pose a security threat as they may be poorly managed or insufficiently secured. Any attacker in the vicinity can easily get onto the internal network through a rogue AP, bypassing all perimeter security measures. Existing detection solutions work well for(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 not(More)
The communication overhead has become one of the bottlenecks of SVM (shared virtual memory). Many methods have been taken to improve the performance of SVM. However, these can't obtain the improvement as expected. In order to get further utility of communication hardware and reduce unnecessary overhead, a prototype with the ability of RDMA is designed and(More)
Interconnect network, host interface, and communication protocol determine the overall performance of message passing on cluster systems. Most previous work only focuses on these aspects separately. This paper describes the design of FRAMP (virtual memory based fast remote direct memory access and message passing network), including the crossbar-based(More)
