Problems solved by technology

[0004] In the early development process of the power SCADA system using the IEC60870-5-101 protocol and the DNP3.0 protocol, the problem of information security has not yet emerged, and information security is usually not an important design requirement. Therefore, in order to improve performance requirements and save cost, usually ignoring the consideration of complete information delivery

Abstract

The invention discloses a system for information safety protection of an electric power supervisory control and data acquisition (SCADA) system. The system comprises a safety equipment management system, a station level electric power SCADA system safety protection device and an on-site terminal level electric power SCADA system safety protection device, wherein the safety management system is positioned in a power supply control center and becomes one component part of the electric power SCADA system main station system to manage the long-range station level electric power SCADA system safety protection device and the on-site terminal level electric power SCADA system safety protection device. The station level electric power SCADA system safety protection device is placed in a sub-station level electric power SCADA system device of the electric power SCADA system. The on-site terminal level electric power SCADA system safety protection device is placed in an electric power SCADA field device of an electric network field. The system has the main function of providing fine granularity and electric power production control service-based application layer safety protection for the electric power SCADA system, is used for ensuring the safety of 'four-remote functions' including a remote control function, a remote signaling function, a remote sensing function and remote regulatingfunction of the electric power SCADA system, and the safety of a communication channel of the electric power SCADA system, has electric power SCADA system intrusion detection and access control abilities, and has strong electric power service pertinence.

Description

technical field [0001] The present invention relates to the IEC60870-5-101 protocol and the DNP3.0 protocol widely used in the field of power SCADA systems at present, and especially relates to providing information security protection capabilities for power SCADA systems using the IEC60870-5-101 protocol and the DNP3.0 protocol A power SCADA system information security protection system. Background technique [0002] The American Igesis Technology Company applied in China in February 2006, the invention application number is 200480022852.5, and the name of its invention is "Method, system and device for making communication security of monitoring and data acquisition (SCADA)", the invention mainly The protection target is the security of the link layer, not the security of the business layer. It does not combine the specific network structure and engineering practice of my country's power control network application, and does not involve more design in terms of equipment eng...
