Oil and gas pipe network SCADA security defense method based on factor neural network

Abstract

The invention discloses an oil and gas pipe network SCADA security defense method based on a factor neural network. The method is characterized in that security defense of an SCADA system with distributed type characters is achieved through various analysis type factor nerve cells and a coordination mechanism of the factor nerve cells. The nerve cells comprise execution nerve cells, factor knowledge base nerve cells, statistic nerve cells, tracking nerve cells, analysis nerve cells, evaluation nerve cells, early-warning nerve cells, management nerve cells and scheduling and assembling nerve cells. The execution nerve cells are distributed on various levels of industrial personal computers, engineer stations and operator stations in a three-layer network structure of the distributed SCADA system to capture and judge behavior factors (for short, factors) of operation programs and compare the behavior factors with factor knowledge base in the factors to judge whether the programs are rogue programs, and corresponding measurements are adopted; the execution nerve cells are coordinated with other nerve cells to achieve security defense, threat early warning and security evaluation of the overall SCADA system.

Description

technical field [0001] The invention relates to a safety defense method for oil and gas pipeline network SCADA based on a factor neural network, which is used for security protection of industrial computers, engineer stations, operator stations and other computers in the large-scale oil and gas gathering and transportation pipeline network SCADA system, and improves the security of oil and gas pipelines. Network SCADA system security protection level. Background technique [0002] With the continuous development of the Internet age, computers have gradually spread to all aspects of our lives. For industrial systems, computers have become an important part of them. While computers have brought great convenience to industrial systems, they have also brought huge security risks. In 2010, the computer system of Iran's nuclear facilities was attacked by the Stuxnet virus, and about 900 centrifuges stopped working. Stuxnet was the world's first computer virus written for indust...

Problems solved by technology

But they all have a common fatal shortcoming, there is serious hysteresis

The hysteresis brought about by this passive defense often makes the defense capabilities of the above defense technologies greatly reduced against unknown attacks.

In addition, for the existing oil and gas gathering and transportation pipeline network SCADA system, production shutdown is not allowed during the transformation process, so there are certain limitations in the transformation and application of firewall and other hardware security isolation technologies in industrial systems
