Intrusion Prevention Systems (IPSs) not only attempt to detect attacks but also block malicious traffic and pro-actively tear down pertinent network connections. To effectively thwart attacks, IPSs have to operate both in real-time and inline fashion. This dual mode renders the design/implementation and more importantly the testing of IPSs a challenge. In(More)
We describe our approach to modeling timing of cell signaling systems in which existing information about the system spans from detailed mechanistic knowledge to much coarser observations about cause and effect. The results for several models emphasize the fact that the selection of timing implementation can have both qualitative and quantitative effects on(More)
Sessions generated by Instant Messaging and Peer-to-Peer systems (IM/P2Ps) not only consume considerable bandwidth and computing resources but also dramatically change the characteristics of data flows affecting both operation and performance of networks. Most IM/P2Ps have known security loopholes and vulnerabilities making them an ideal platform for(More)
The smart buildings today have various sensors to monitor its energy consumption, and will automatically adjust itself based on occupancy. However, current approaches are optimized for reducing energy consumption while preserving user experience. We believe that proactively modifying occupants' behavior is necessary to further reduce their energy footprint.(More)
