Current interactions have become a form of social exchange where participants must deal with complexity, uncertainty and risk. We propose a policy specification approach that combines social sciences and trust theory to facilitate ad-hoc interactions of self-interested parties in open environments. Our socio-cognitive approach allows us to reason about uncertainty and risk involved in a transaction, and automatically calculate the minimum trust threshold needed to mitigate the vulnerabilities. The trust threshold comprises the core of security policies that govern the interactions. The threshold calculation is based on balancing objective and subjective trust components, which together predict that a transaction will result in an acceptable outcome. We propose to apply the prospect theory (D. Kahneman and A. Tversky, 1979) to specify policies that determine a set of acceptable outcomes. We present the trust threshold negotiation primitives.","PeriodicalId":240693,"journal":{"name":"Eighth IEEE International Workshop on Policies for Distributed Systems and Networks (POLICY'07)","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123956897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the case of authorization decisions in large distributed systems, policies offer the potential to abstract away from the details of who is allowed to access which services, under which conditions. This layer of abstraction is both a challenge and an opportunity: policy-driven distributed authorization systems may be more manageable, scalable, available, and secure than previous approaches---or they may be just the opposite. In the talk that accompanies this paper paper, we survey the status of the field and its near- term prospects, from both a theoretical and a practical perspective, and point out the major barriers to the adoption of policy-driven authorization systems in industry.","PeriodicalId":240693,"journal":{"name":"Eighth IEEE International Workshop on Policies for Distributed Systems and Networks (POLICY'07)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124228882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three levels of policies are defined: the high level, the specification level and the low level. The policy representation for each level is given.

In this paper we demonstrate that a policy-driven solution is applicable for the management of spectrum markets, and we present a decentralised and lightweight framework for implementing such markets in networked environments.","PeriodicalId":240693,"journal":{"name":"Eighth IEEE International Workshop on Policies for Distributed Systems and Networks (POLICY'07)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122676170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Large scale distributed systems often produce event streams containing large volumes of low-level events. In many cases, these streams also contain multimedia data (consisting of text, audio or video). Hence, a key challenge is to allow policy writers to specify obligation policies based on high-level events, that may be derived after performing appropriate processing on raw, low-level events. In this paper, we propose a semantic obligation policy specification language called Eagle, which is based on patterns of high-level events, represented as RDF graph patterns. Our policy enforcement architecture uses a compiler that builds a workflow for producing a stream of events, which match the high-level event pattern specified in a policy. This workflow consists of a number of event sources and event processing components, which are described semantically. We present the policy language and enforcement architecture in this paper.","PeriodicalId":240693,"journal":{"name":"Eighth IEEE International Workshop on Policies for Distributed Systems and Networks (POLICY'07)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129897130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The automated policy generation problem is difficult in its own right. It becomes even more challenging when the context environment to consider is a mobile ad hoc network. We have designed an optimization-based, utility-driven approach aimed at generating optimal policies with respect to the given network objectives. The main novelty of this approach is in the combination of optimization heuristics and network simulation to solve the problem. We describe this approach, present the software architecture of our implementation, and illustrate the approach with a case study on automated generation of DiffServ-based QoS policies for a 50-node mobile ad hoc network.","PeriodicalId":240693,"journal":{"name":"Eighth IEEE International Workshop on Policies for Distributed Systems and Networks (POLICY'07)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130153181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
