If you missed this excellent live webcast with Evren Sirin, CTO, Clark & Parsia, the recorded webcast is now available. You also can meet Evren in Washington DC, November 29-December 1, 2011 for SemTechBiz DC. The customer mentioned in this case study, JP Morgan Chase, will be co-presenting and discussing how they are implementing Access Control using Semantic Technologies.
Access control is an essential part of nearly every IT system; especially in domains dealing with sensitive information such as financial accounts, personal health records, etc. The Oasis standard XACML provides a high-level XML-based language to describe access control policies for distributed resources. However, as systems get larger and more complex, the maintenance and analysis of these policies become an expensive and burdensome task.
In this webcast, we describe how semantic technologies and automated reasoning techniques can be used to address the policy management problem. We explain how policy analysis services such as formal policy verification, unit testing, and redundancy detection can be provided for XACML policies. We also discuss how Web Ontology Language (OWL) ontologies can be used to enhance XACML policies with richer descriptions of roles and resources.
