First CFP: IEEE SECURECOMM SECOVAL'06, IEEE Xplore and JoATC proceedings, 2nd Workshop on the Value of Security through Collaboration CALL FOR PAPERS - SECOVAL 2006 - The Value of Security through Collaboration in cooperation with IEEE/CREATE-NET SECURECOMM'06, http://www.securecomm.org. As last year, all accepted papers will appear on the SECURECOMM CDs and in IEEE Xplore. Then, the best contributions will be revised and extended for publication in a special issue of the Journal of Autonomic and Trusted Computing published by American Scientific Publishers. It is recommended to send an email confirming your expression of interest to participate to the workshop and submit a paper by April 15, 2006 to secoval@trustcomp.org. Aug. 28 - Sep. 1, 2006, Baltimore, MD, USA Aims and scope of the SECOVAL Workshop: Security is usually centrally managed, for example in a form of policies duly executed by individual nodes. The SECOVAL workshop covers the alternative trend of using collaboration and trust to provide security. Instead of centrally managed security policies, nodes may use specific knowledge (both local and acquired from other nodes) to make security-related decisions. For example, in reputation-based schemes, the reputation of a given node (and hence its security access rights) can be determined based on the recommendations of peer nodes. As systems are being deployed on ever-greater scale without direct connection to their distant home base, the need for self-management is rapidly increasing. Interaction after interaction, as the nodes collaborate, there is the emergence of a digital ecosystem. By guiding the local decisions of the nodes, for example, with whom the nodes collaborate, global properties of the ecosystem where the nodes operate may be guaranteed. Thus, the security property of the ecosystem may be driven by self-organising mechanisms. Depending on which local collaboration is preferred, a more trustworthy ecosystem may emerge. The research addressed by the workshop can be roughly divided into three main areas, each answering the related research questions. Contributions should address at least one of these areas. It is expected that the workshop will address all of them. 1. It is necessary to define the reasoning behind current trends in security through collaboration. Does such security solve security issues that cannot be tackled by traditional security solutions? What is the added value of security through collaboration? In the same line of thought, we should investigate the value of trust as a foundation of security. Specifically, changes to the nature of the security perimeter and possible pervasiveness of trust-based security through collaboration require investigation regarding scalability of such solutions in a world, as envisioned by Weiser, where billions of computing entities are woven into the fabrics. Further, we should address the dynamics of such security that makes it possible to draw from trusted entities (both human and computers) and extend trust towards strangers, possibly through the self-learning of individual nodes. 2. The second set of contributions is expected to address the different approaches to and models of security through collaboration. Models of security and trust used for security through collaboration should take into account several aspects of trust evaluation, including trust collection of evidence, the underlying trust methodology and model, the decision making process and the learning process. Reputation schemes have been already mentioned as one example, but there are several other possible collaboration models, rewarding for example individual experience or centrally managed evidence. Further, models may consist of collaboration supervised by administrators or users or collaboration that is fully automated, where the computing entities collaborate without human intervention and make security decisions on behalf of their owners. Self-organising and self-management mechanisms seem to be important for the emergence of a more trustworthy ecosystem of collaborating nodes. 3. Security through collaboration brings its own unique set of problems and risks. For example, privacy can be impacted by different aspects of collaboration, as more information about individuals may lead to better trust estimates. This inevitable breach of privacy may affect not only individuals but may also propagate through the network of relationships. Further, collaboration invites new types of attacks that require new threat analysis. A well-known example of the vulnerabilities introduced by implicit trust relations is the Internet Worm that penetrated 5% of the Internet in 1988: once logged into one machine, remote login into another machine part of the trust relations did not require another login/password check. Of course, many possible types of attack on different trust metrics exist, including identity usurpation attacks and identity multiplicity attacks such as Douceur's Sybil attack. Further, certain network topologies can be more vulnerable to specific forms of attacks and certain network nodes (e.g. most trusted ones) can be more likely to be attacked, which raises questions regarding additional protection such nodes may require. Topics of interest to the workshop include, but are not limited to: * Approaches to security through collaboration * Specificities of security through collaboration * Trust methodologies, models and metrics * Interoperability and standardization of trust metrics * Value and meaning of trust * Trust-based security decision process * Security based on reputation and recommendations * Self-organisation mechanisms for a more secure digital ecosystem * The role of emergence in dynamic trust models * Collaborative autonomic computing * Value and models of networks of collaborators and information sharing * Threat and risk analysis of security through collaboration * Attacks due to collaboration and mitigation of these attacks * Technical trust of the underlying infrastructure used for deployment * Costs and benefits of trust and collaboration based security compared to other models * Privacy and legal aspects of security through collaboration Submission guidelines are posted on the SECOVAL 2006 website (http://www.trustcomp.org/secoval/), which always contains the latest updates: Authors are invited to submit papers formatted according to IEEE conference style 2-column (from a 2-page extended abstract to 10 pages limit).
