    Towards Proactive Policies supporting Event-based Task Delegation

    Export to Mendeley

    Delegation mechanisms are receiving increasing interest from the research community. Task delegation is a mechanism that supports organisational flexibility in the human-centric workflow systems, and ensures delegation of authority in access control systems. In this paper, we consider task delegation as an advanced security mechanism supporting policy decision. We define an approach to support dynamic delegation of authority within an access control framework. The novelty consists of reasoning on authorisation dependently on task delegation events, and specifies them in terms of delegation policies. When one of these events changes, our access policy decision may change proactively implying dynamic delegation of authority. Existing work on access control systems remain stateless and do not consider this perspective. We highlight such limitations, and propose a task delegation framework to support proactive enforcement of delegation policies.

    Description

    Title : Towards Proactive Policies supporting Event-based Task Delegation
    Author(s) : Khaled Gaaloul, Philip Miseldine, François Charoy
    Abstract : Delegation mechanisms are receiving increasing interest from the research community. Task delegation is a mechanism that supports organisational flexibility in the human-centric workflow systems, and ensures delegation of authority in access control systems. In this paper, we consider task delegation as an advanced security mechanism supporting policy decision. We define an approach to support dynamic delegation of authority within an access control framework. The novelty consists of reasoning on authorisation dependently on task delegation events, and specifies them in terms of delegation policies. When one of these events changes, our access policy decision may change proactively implying dynamic delegation of authority. Existing work on access control systems remain stateless and do not consider this perspective. We highlight such limitations, and propose a task delegation framework to support proactive enforcement of delegation policies.
