A Fuzzy Layered Security Management in Distributed Scheme

Abstract: This paper presents a layering system that provides security in distributed environment such as network. There is probability to vanish security relation with disability of nodes, but in proposed layering system enables to keep security relations after disability some nodes. Security relations belong to 3 different sets, so a fuzzy system combines the security rules that describe the security policy. One layer in the proposed system assign to the security rules and another layer assign to the objects in the system. Objects are grouped to security rules. Grouping the objects is done via clustering. Access requests must be sent to security layer to check and then it decides to allow them. Fuzzy clustering is used in this paper to cluster the objects for its flexibility.
