A New Information Security Model Based on Network Service Protection

The traditional security model, aimed at ensuring privacy and integrity of information, has limitations on special networks such as the electric power information network, which emphasizes the stable operation and cooperation of the electricity service. Then a new idea on protection of network service security is proposed in this paper. Firstly, divide the network service into two parts as processes and data with security identifiers given respectively. The non-alterability of implementation logic in network service holds to ensure the continuous and stable operation of the service. Then the licensed access to data is implemented by comparison of the security identifiers of processes and data. In the end, a new information security model based on the network service protection is established, followed with the security features and possible implementation.
