Configuration files, command-line arguments and environment variables are the dominant tools for local configuration management today. When accessing such program execution environments, however, most applications do not take context, e.g. the system they run on, into account. The aim of this paper is to integrate unmodified applications into a coherent and context-aware system by instrumenting...

We propose and prove sound a novel, purely dynamic, flowsensitive monitor for securing information flow in an imperative language extended with DOM-like tree operations, that we call Core DOM. In Core DOM, as in the DOM API, tree nodes are treated as first-class values. We take advantage of this feature in order to implement an information flow control mechanism that is finer-grained than previ...

In this paper, we propose a five-step approach to detect obfuscated malware by investigating the structural and behavioural features of API calls. We have developed a fully automated system to disassemble and extract API call features effectively from executables. Using n-gram statistical analysis of binary content, we are able to classify if an executable file is malicious or benign. Our exper...

NetTap is a new platform for prototyping, fieldtesting, and deploying network services. NetTap is based on a PC running FreeBSD. NetTap can be configured as a bridge, router, or host. NetTap’s API allows user-level network applications to send or receive packets, on standard network adapters, without copying or system call overheads. NetTap’s watchdog timer and simple bypass switch can be confi...

Database systems as basis for CAD frameworks have to provide data management as well as transaction management facilities meeting the requirements of design applications. One of the most important features is an application programming interface (API) supporting design tool implementation as well as integration of design tools into the CAD framework by integrating a database language into a hos...
