Access Control List Mediation System for Large-Scale Network

Large-Scale network such as the Internet consist of a large number of sub-networks. Since each subnetwork has management privileges and policies individually, it is difficult to respond to harmful traffic such as warm viruses that affect entire networks. In this paper, we propose a high-level policy language and a middle-level data structure. They were named Triton language and Common Access Management Form (CAMF). It enables the administrator to authorize a policy effectively and rapidly. Large-scale networks have a number of administrators so that policy collision can occur. Access control list mediation system selects or adapts the most important policy among colliding policies through a policy importance valuation.
