| Abstract: | In this paper, we present our arguments about security enhanced Knowledge Management (KM) systems, which enable -transparent to the user - diffusion of knowledge, filtered through security policy mechanisms. We provide identification and access to security related knowledge assets, based on the use of software agents, which interact between several organizational domains and authorize access to knowledge resources. The authorization process is based on an automated policy framework, which handles negotiations between different organizational domains, and provides transparent access to knowledge assets. Users benefit from the system by acquiring knowledge not only from their domain, but by being able to query different organizations or different domains on grounds of a common for all co-operating domains security policy framework. The role of ontologies is eminent in exploiting heterogeneous knowledge sources. |
