Healthcare system consists of a number of sub-networks by physically. Since each sub-network 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 for the healthcare system. They were named Triton language and Common Access Management Form (CAMF) [Jangha Kim, et. al., 2004]. It enables the administrator to authorize a policy effectively and rapidly. Healthcare system networks have a number of administrators so that policy collision can occur. Security policy management system selects or adapts the most important policy among colliding policies through a policy importance valuation.
