The Design And Implementation Of Safety Management Module Of JiLin CNC Switch Network Management System

With the picking up of the completing situation in the telecommunication market, carrier go deep into reforming the system of maintenance step by step, the higher demand was brought forward to construct the network management system result by the centralized operating and maintenance.The function of safety management is one of the five function fields in TMN which defined by ITU-T. Safety management can implement the management of the accessing safety controlling to the whole network management system, includes the definition and validation of user identity, as well as the safety accessing controlling of all resources managed by system.The system safety controlling model is one of popular advanced purview management controlling method at present. The safety management module of JiLin CNC switch network management system adopts some idea based on the need of itself. Its character is that the awarding and abrogation of user purview was implemented by distributing and abrogating the roles, and providing the role distributing rule and operation checking rules. The purview management person defines various roles according demand, and set the appropriate accessing purview, and users are distributed the different roles according their duty. So the whole control process is divided into two parts, the accessing purview are related to roles and the roles are related to users, so the logic separation of user and accessing purview is implemented.The safety management system was implemented based on Windows 2003 Server, the information such as users, roles and purview were stored by the active directory of Windows 2003 Server, which provide the distinguish right API and authorization API to manage the distinguish right and the authorization. The users of network management system and users of Windows system are in one because of integrating the resolving scheme of Windows active directory, when the user...
