SINOPEC News Network News Since this year, the Second Gas Production Plant of North China Oil and Gas Branch has continued to deepen the construction of production informatization, and has established "automatic data collection, automatic monitoring of production processes, emergency chain protection, and intelligent protection of production sites" in the Dongsheng Gas Field.
The automatic control system realizes automatic production functions such as single well remote shut-off, valve liquid level interlocking control, and fire alarm automatic pressure relief
.
Different from the traditional meaning of information security, the accidental shutdown of installations and important equipment caused by the risks of industrial control systems will result in the terminal of gas production business and huge economic losses
.
The information room of North China Gas Production Plant II, which is in charge of the project, put the usability in the CIA model as the top priority and worked out a set of technical standards and management methods suitable for industrial control safety in Dongsheng Gas Field to ensure the absolute safety of the control system.
Top-level design to identify industrial control security assets
According to the Purdue industrial system model, the ICS of the second gas production plant is divided into office area, industrial isolation area and production area, the boundaries of different security areas are defined and the industrial control assets in them are identified, and the industrial control system firewall and one-way gatekeeper are deployed at the boundary.
Technical defense plus management, focusing on the implementation of strategies
The information room is closely integrated with production, regular inspection of valves, controllers and other automatic control equipment to eliminate underlying risks; full life cycle management, convenient control logic based on causality diagrams, deployment of safety instrumented systems and ESD emergency cutoffs to ensure the safety and reliability of the chain and loop; Redundant design.
Take precautions and explore new prevention and control technologies
In accordance with the requirements of the "Implementation Regulations for the Safety Protection of Instrumentation and Control System of Sinopec Industry", the information room was simple and stubborn, concentrated on researching and analyzing the components and processes of the control system, refined more than 50 whitelists, formulated 126 security policies, and reinforced engineer stations and operations With more than 10 staff stations, it regards industrial control safety as equivalent to production safety; it maintains integrity and innovation, actively invites business exchanges with safety companies such as Petrochemical Yingke, and formulates situational awareness, penetration testing and other solutions based on actual conditions
Industrial safety has a long way to go.
