FORTES: Forensic Information Flow Analysis of Business Processes

Authors: Rafael Accorsi and Günter Müller

Published in: Dagstuhl Seminar Proceedings, Volume 10141, Distributed Usage Control (2010)

Abstract
Nearly 70% of all business processes in use today rely on automated workflow systems for their execution. Despite the growing expenses in the design of advanced tools for secure and compliant deployment of workflows, an exponential growth of dependability incidents persists. Concepts beyond access control focusing on information flow control offer new paradigms to design security mechanisms for reliable and secure IT-based workflows. This talk presents FORTES, an approach for the forensic analysis of information flow properties. FORTES claims that information flow control can be made usable as a core of an audit-control system. For this purpose, it reconstructs workflow models from secure log files (i.e. execution traces) and, applying security policies, analyzes the information flows to distinguish security relevant from security irrelevant information flows. FORTES thus cannot prevent security policy violations, but by detecting them with well-founded analysis, improve the precision of audit controls and the generated certificates.

08491 Abstracts Collection – Theoretical Foundations of Practical Information Security

Authors: Ran Canetti, Shafi Goldwasser, Günter Müller, and Rainer Steinwandt

Published in: Dagstuhl Seminar Proceedings, Volume 8491, Theoretical Foundations of Practical Information Security (2009)

Abstract
From 30.11. to 05.12.2008, the Dagstuhl Seminar 08491 ``Theoretical Foundations of Practical Information Security '' was held in Schloss Dagstuhl~--~Leibniz Center for Informatics. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put together in this paper. The first section describes the seminar topics and goals in general. Links to extended abstracts or full papers are provided, if available.

08491 Executive Summary – Theoretical Foundations of Practical Information Security

Authors: Ran Canetti, Shafi Goldwasser, Günter Müller, and Rainer Steinwandt

Published in: Dagstuhl Seminar Proceedings, Volume 8491, Theoretical Foundations of Practical Information Security (2009)

Abstract
Designing, building, and operating secure information processing systems is a complex task, and the only scientific way to address the diverse challenges arising throughout the life-cycle of security criticial systems is to consolidate and increase the knowledge of the theoretical foundations of practical security problems. To this aim, the mutual exchange of ideas across individual security research communities can be extraordinary beneficial. Accordingly, the motivation of this Dagstuhl seminar was the integration of different research areas with the common goal of providing an integral theoretical basis that is needed for the design of secure information processing systems.
