Applications of Intrusion-Tolerance Pre-response in the Grid Enterprises

With the automation level of the computer networks and grid rising, the dependence of the electric power enterprise on information systems is growing, while the security problems faced by become stronger, so using traditional security technologies only to maintain the system security can no longer meet the enterprise requirements. In this paper, against the information network characteristics of the power enterprise, combined with intrusion tolerance theory, we put forward the security model based on pre-response intrusion tolerance technology used by power enterprise information systems. The model inherits the intrusion tolerance capacity and intrusion tolerance performance of the pre-response intrusion tolerance technology, and can provide a more comprehensive fault tolerance and intrusion tolerance capabilities to ensure the reliability and the uninterruptedness of the information system services.
