Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 16461 "Assessing ICT Security Risks in Socio-Technical Systems". As we progress from classic mechanical or electrical production systems, over ICT systems, to socio-technical systems, risk assessment becomes increasingly complex and difficult. Risk assessment for traditional engineering systems assumes the systems to be deterministic. In non-deterministic systems, standard procedure is to fix those factors that are not deterministic. These techniques do not scale to ICT systems where many risks are hard to trace due to the immaterial nature of information. Beyond ICT systems, socio-technical systems also contain human actors as integral parts of the system. In such socio-technical systems there may occur unforeseen interactions between the system, the environment, and the human actors, especially insiders. Assessing ICT security risks for socio-technical systems and their economic environment requires methods and tools that integrate relevant socio-technical security metrics. In this seminar we investigated systematic methods and tools to estimate those ICT security risks in socio-technical systems and their economic environment. In particular, we searched for novel security risk assessment methods that integrate different types of socio-technical security metrics.

Online Privacy: Towards Informational Self-Determination on the Internet (Dagstuhl Perspectives Workshop 11061)

Authors: Simone Fischer-Hübner, Chris Hoofnagle, Ioannis Krontiris, Kai Rannenberg, and Michael Waidner

Published in: Dagstuhl Manifestos, Volume 1, Issue 1 (2011)


Abstract
While the collection and monetization of user data has become a main source for funding ``free'' services like search engines, online social networks, news sites and blogs, neither privacy-enhancing technologies nor its regulations have kept up with user needs and privacy preferences. The aim of this Manifesto is to raise awareness for the actual state of the art of online privacy, especially in the international research community and in ongoing efforts to improve the respective legal frameworks, and to provide concrete recommendations to industry, regulators, and research agencies for improving online privacy. In particular we examine how the basic principle of informational self-determination, as promoted by European legal doctrines, could be applied to infrastructures like the internet, Web 2.0 and mobile telecommunication networks.

Online Privacy: Towards Informational Self-Determination on the Internet (Dagstuhl Perspectives Workshop 11061)

Authors: Simone Fischer-Hübner, Chris Hoofnagle, Kai Rannenberg, Michael Waidner, Ioannis Krontiris, and Michael Marhöfer

Published in: Dagstuhl Reports, Volume 1, Issue 2 (2011)


Abstract
The Dagstuhl Perspectives Workshop "Online Privacy: Towards Informational Self-Determination on the Internet" (11061) has been held in February 6-11, 2011 at Schloss Dagstuhl. 30 participants from academia, public sector, and industry have identified the current status-of-the-art of and challenges for online privacy as well as derived recommendations for improving online privacy. Whereas the Dagstuhl Manifesto of this workshop concludes the results of the working groups and panel discussions, this article presents the talks of this workshop by their abstracts.
