Disaster recovery evaluation PROC model framework based on information flow

To improve the level of disaster recovery construction, combined with disaster recovery evaluation standards, this paper proposed disaster recovery evaluation PROC model framework based on information flow. The framework achieved real-time monitoring state of disaster recovery ability by combining disaster recovery resource-based static evaluation with system vulnerability indicators-based dynamic evaluation. At the same time, it added the knowledge base system to the module, to achieve a certain degree of automation and transparence of disaster recovery evaluation. Finally, it proposed the time dimension-based planning framework for disaster recovery evaluation, ultimately to achieve normalization and refinement of disaster recovery evaluation.
