Device drivers are essential components of any operating system (OS). They specify the communication protocol that allows the OS to interact with a device. However, drivers for new devices are usually created for a specific OS version. These drivers often need to be backported to the older versions to allow use of the new device. Backporting is often done manually, and is tedious and error prone....
Tracing allows the analysis of task interactions with each other and with the operating system. Locating performance problems in a trace is not trivial because of their large size. Furthermore, deep knowledge of all components of the observed system is required to decide whether observed behavior is normal. We introduce TraceCompare, a framework that automatically identifies differences between groups...
Anomaly-based Intrusion Prevention Systems have been studied to prevent zero-day attacks. However these existing systems can't prevent mimicry attacks because of the inadequacy of monitoring accuracy. Moreover, they provide no continuity for monitored applications when they have been compromised. In this paper, we propose a novel Intrusion Prevention System named Belem that detects anomaly states...
