摘要：In order to solve the implementation and realization efficiency problem of the network information system security policy, an improved object-oriented Rete algorithm and its network structure model are proposed, and on this basis, the rule engine is introduced, where the implementation and realization steps and efficiency analysis are given. Result shows that the algorithm and network structure can effectively improve the efficiency of system enforcement and realization. The technology can be adapted to establishing and controlling the policy service in the extensive network environment.
