Research And Design Of Cluster System For Audit Of Operation And Maintenance

As information security has gained more and more concerns and attentions of the whole society, the security requirements of information systems and data also get servere. The State Grid Corporation is doing some security work for the internal operation and maintenance behavior at the same time it guards against external attacks, and the work has gain some good effect. However, the operation and maintenance security audit system reveals some problems in some working situations:cumbersome and time-consuming process of implementation and deployment; complex and difficult expansibility; low resource utilization; difficult to improve performance; difficult and time-consuming recovery. The operation and maintenance security audit system is the only entry of company’s operation and maintenance work, so the key factor of doing operation and maintenance work better are the system’s performance and stability. In order to solve the problems mentioned above, one cost-effective way is cluster transformation.In this paper, firstly the usage and feedback of the operation and maintenance security audit system hot standby deployment are introduced and analyzed, and the scene real needs of the operation and maintenance security audit system are summed up. On this basis, then scrutiny and study the scheme and technologies used in varied kinds of load balancing cluster, and develop a load balancing scheme fit for the operation and maintenance security audit system. The greatest feature of the scheme is equivalence of all nodes, which achieves effects as high availability, high performance, scalable, fault-tolerant, freely configurable and smoothing extension. Finally, implement the operation and maintenance security audit load balancing cluster system, and propose solutions to cluster problem and security risks of this system.
