Model-based Security Engineering

Dr Jan Jurjens Technical University of Munich

The current state of the art in security-critical software is far from satisfactory: New security vulnerabilities are detected on an almost daily basis. To improve this situation, we develop techniques and tools that perform an automated analysis of software artefacts for security requirements (such as secrecy, integrity, and authenticity). These artefacts include specifications in the Unified Modeling Language (UML), annotated source code, and run-time data such as security permissions. The security analysis techniques make use of model-checkers and automated theorem provers for first-order logic. We give examples for security flaws found in industrial software using our tools.

Social Software is...


Social Software
Social Software can be thought of as "software which extends, or derives added value from, human social behaviour - message boards, musical taste-sharing, photo-sharing, instant messaging, mailing lists, social networking."

Interacting with other people not only forms the core of human social and psychological experience, but also lies at the centre of what makes the internet such a rich, powerful and exciting collection of knowledge media. We are especially interested in what happens when such interactions take place on a very large scale -- not only because we work regularly with tens of thousands of distance learners at the Open University, but also because it is evident that being part of a crowd in real life possesses a certain 'buzz' of its own, and poses a natural challenge. Different nuances emerge in different user contexts, so we choose to investigate the contexts of work, learning and play to better understand the trade-offs involved in designing effective large-scale social software for multiple purposes.
