There are considerable number of approaches to policy specification both for security management and policy driven network management purposes as reported in [20]. This specification sort security policies into two basic types: authorization and obligation policies. Most of the researches in security policies specification over the years focus on authorization policy modelling. In this paper, we report our approach in the design and Modelling of obligation Policy as delegation in information security by considering separation of duty and trust as pre-requisite conditions for delegation. The formal structures of the Delegation models developed was adapted from the Mathematical structures of Separation of duty (both Static and Dynamic SoD) in RBAC environment as described in [8] and [16]. Three factors of Properties, Experiences and Recommendation as described in [22] were used for the Trust Modelling. Future works proposed include the development of a formal model for revocation after delegation and integration of appropriate authorization policy with the model. |
