In recent years, the implementation of information security level protection has become a critical focus for various industries across the country. The power sector, in particular, has developed its own industry-specific standards tailored to the unique characteristics and current security needs of its information systems. This article explores the protection requirements set forth by the power industry for information security levels and outlines the methods used to apply both national basic indicators and industry-specific indicators during the rating and protection evaluation process.
The power industry's information system encompasses not only production, dispatch, and control systems related to power generation, transmission, transformation, distribution, and consumption, but also management systems such as those for production and marketing. Prior to the formalization of the level protection framework, the industry had already recognized the importance of information security. In 2005, the Electricity Regulatory Commission issued the "Regulations for the Protection of Secondary Power Systems" (Order No. 5), which laid the foundation for subsequent protective measures. Following this, several key documents were introduced, including the "Overall Protection Plan for Power System Secondary Systems," the "Safety Protection Plan for Provincial and Above Dispatch Centers," and the "Safety Protection Plan for Substations."
As the power industry progressed, it adopted a cautious and strategic approach to implementing information security level protection. Pilot projects were conducted to better understand the unique demands of power systems, leading to the development of industry-specific protection requirements. The Ministry of Public Security’s "Guiding Opinions on Conducting the Rectification and Improvement of Information Security Level Protection and Safety Construction" further emphasized that key industry sectors could follow national standards while tailoring them to their specific needs. Based on these guidelines, the power industry formulated its own "Basic Requirements for the Protection of Power Industry Information System Security Levels" and initiated pilot assessments to refine its approach.
This article summarizes the core requirements for information security level protection within the power industry, focusing on how both national and industry-specific indicators are applied in the evaluation process. It also highlights the differences between general and industry-specific standards, showing how the power sector has enhanced and adapted national requirements to meet its unique challenges.
The application of these standards is evident in pilot evaluations conducted by the State Grid Corporation, where representative systems at different security levels were assessed. One such example is a financial management information system with a security level of S2A3G3, which includes functions like budget management, accounting, and electronic payments.
During the evaluation process, two types of indicators are typically used: basic indicators derived from national standards and special indicators tailored to the power industry. These indicators guide the assessment of technical and management requirements, ensuring that systems are evaluated based on their actual security needs. The evaluation methodology includes sampling techniques to efficiently assess large and complex systems, ensuring that the results accurately reflect the security status of the information systems.
Overall, the power industry continues to evolve its approach to information security level protection, adapting to new technologies such as smart grids and increasing automation. As the scope of evaluation expands, so do the challenges, requiring continuous refinement of assessment methods to ensure robust and effective protection of critical infrastructure.
Analog Orp sensors and analog Orp electrodes are important and critical sensing components for measuring Orp data.Selecting the correct ORP Sensor/electrode is crucial to obtaining the best measurement results.
ORP, also known as oxidation-reduction potential, represents the oxidation-reduction ability of water, and the unit is mV. When the ORP sensor reads a negative number, this means that the substance being measured is a reducing agent, and when the reading is positive, it means that it is measuring an oxidizing agent. The reading of ORP will reflect the degree of pollution or disinfection of water, and it is an important indicator of water quality. Although it cannot independently reflect the quality of water, it can reflect the ecological environment of water bodies in combination with other water quality indicators.
If the ORP value is low, it indicates that the content of reducing substances or organic pollutants in the wastewater treatment system is high, the concentration of dissolved oxygen is low, and the reducing environment is dominant.
If the ORP value is high, it indicates that the concentration of organic pollutants in the wastewater is low, the concentration of dissolved oxygen or oxidizing substances is high, and the oxidation environment is dominant.
Daruifuno's analog ORP sensor has two types of flat platinum and circular platinum, and the measurement range is also different. Customers can choose according to their needs.The analog ORP electrode is a double salt bridge design with Ag/Cl reference electrode. We also have glass material and plastic shell packaging models.
Analog ORP electrodes cannot transmit signals by themselves and need to be equipped with a transmitter. Our online pH ORP controllers can be connected to analog ORP sensors to achieve more display, control and output functions. We can also customize BNC connectors.
The main applications of ORP sensors include: chlorine and disinfection, cooling towers, swimming pools, water treatment, poultry processing, pulp bleaching, etc.
