Semantic integration technologies are quickly creating an environment where both structured and unstructured data, once isolated in distributed silos and differing formats, can now be integrated to provide a more comprehensive picture of activities within the virtual enterprise. While military services increase integration capabilities and evolve away from stove-piped data silos, access control to enterprise wide integrated data is largely simplistic and inflexible. In the net-centric environment information is being dynamically combined with other information to create new meaning on the fly and the consequences of maintaining the status quo in access control jeopardizes “getting the right information to right people at the right time”, and creates possibility for too lenient controls which violate “need to know” restrictions. Securboration is changing the security paradigm to base it on semantic meaning and context of information, rather than static structure of information. To incorporate semantics, SemPBro leverages Securboration’s experience developing solutions based on knowledge representation and reasoning with semantic technologies such as the OWL Web Ontology Language (and OWL Description Logic), OWL-Services, and Semantic Web Rules Language to infer policy over a wide range of operating conditions.
