Abstract:  Access control is a technology that restricts the use of resources. It is often used to provide certain resource protection capabilities in application systems. It restricts the behavior of resource requesters by restricting their own conditions, use conditions and use obligations. In complex systems, access control technology is usually used to manage the accessible resources. When there are hazardous events in the system, traditional access control model can not provide enough flexibility for the dynamic system environment. In this paper, an adaptive access control model based on hazardous events is proposed, then the dynamic adjustment method of this model is given. Finally, the possible policy conflicts in the process of dynamic adjustment of the model are analyzed based on a case, and the resolution rules of the policy conflicts are determined.

Key words: access control, hazardous events, adaptive adjustment, policy conflict resolution
