In current commodity systems, applications have no way of limiting their trust in the underlying operating system (OS), leaving them at the complete mercy of an attacker who gains...
We present the notion of a type-safe disk (TSD). Unlike a traditional disk system, a TSD is aware of the pointer relationships between disk blocks that are imposed by higher layer...
Vulnerability-driven filtering of network data can offer a fast and easy-to-deploy alternative or intermediary to software patching, as exemplified in Shield [43]. In this paper, ...

EnsemBlue is a distributed file system for personal multimedia that incorporates both general-purpose computers and consumer electronic devices (CEDs). EnsemBlue leverages the cap...
This paper presents three policies for effectively utilizing TCP offload network interfaces that support connection handoff. These policies allow connection handoff to reduce the ...
Operating systems are complex and their behavior depends on many factors. Source code, if available, does not directly help one to understand the OS's behavior, as the behavi...
