Privilege separation has been proposed to reduce exploitation capabilities attackers may gain after successfully infiltrating a process, e.g. a network daemon. In this article we present a highly automated approach for decomposition of existing source code in order to realize such a privilege separation for existing monolithic software. For this, we describe an approach to analyze the source code,...
The major cause of IT security incidents are software issues, hence this article presents an automated approach for source code partitioning and privilege separation. Based on static call graph analysis, functions and program parts of a monolithic software are separated in several processes and grouped by the privilege they need. For the partitioning we introduce a metric that estimates the potential...
Multipath routing allows for a reliable communication in ad-hoc networks, e.g., to transport VoIP calls in disaster scenarios. Due to the usage of different paths in conjunction with Forward Error Correction, failures can be tolerated without interrupting real-time transmissions. However, current multipath algorithms either depend on global topology information, perform an excessive message flooding,...
The cheap and globally available communication infrastructure of the Internet, makes it more and more interesting for companies and governments to also exchange private information over it. However, the often deployed manually configured Virtual Private Networks (VPNs) have certain limitations: While cryptography can ensure the confidentiality, integrity and authentication of transmitted data, the...
Application Layer Multicast (ALM) has become a popular form of content distribution. It shows some favourable properties like inherent scalability and the overcoming of the traditional client-server bottleneck. In the future, a large fraction of the participants in ALM systems will be mobile (eg. smart-phones or netbooks) and demand for a proper inclusion and mobility handling. After analyzing current...
