However, it has been more than a decade since the 2003 "8.14" large-scale power outage in California, but in retrospect, I believe that the lessons learned from the power industry should not be underestimated. At that time, one of the reasons for the partial failure of the power grid to the stability of the grid was that the network and the XA/21 system caused the failure of the early warning system, resulting in the shutdown of a total of 100 power plants including 22 nuclear power plants. . "In today's rapid development of power information security construction, with the entry of intelligence, the power grid is increasingly attacked by computer viruses, logic bombs, and Trojans from the Internet, and next-generation network information security will face more challenges." 2014 On December 23, 2008, Gao Kunlun, director of the China Electric Power Science Research Information Security Laboratory, said at the 2014 Power Industry Informatization Annual Conference hosted by the China Electric Engineering Society Power Information Professional Committee. Intelligentization is the development direction of the power grid, but the smart grid will face various network security challenges. To strengthen grid security, it is necessary to build defenses on its own. Establish a proactive defense system based on trusted computing Nowadays, information security incidents related to power industrial control systems are not uncommon. However, the power grid is related to people's livelihood. Power grid accidents not only affect residents' lives but also threaten national security. “Smart grid, maintaining grid security needs to be well defended. At present, China's power grid defense has developed in two stages: firstly, it is a deep protection system based on border security; then it enters a protection system using domestic software and hardware products. Passive defense, the future development of the power grid will be based on the active defense system of trusted computing." Gao Kunlun said. Wang Jianbin, vice president of Beijing Venus Star Company, has the same view. He said: "Information security issues are attracting more and more attention from all parties. It has become the biggest threat challenge in the software-defined world. With the development of smart grids, big data in the power industry will also become an important strategic asset in China, based on big data analysis. Solving network behavior and data security issues is also a new field actively explored by security vendors. Absolute security is not available. As a professional security vendor, it is necessary to do its utmost to actively explore technological innovation to implement dynamic security protection for the informationization of the power industry." How to achieve self-controllable power grid information security, that is, security defense in the active sense. Gao Kunlun emphasized that the security of infrastructure based on trusted computing should be enhanced. In the power information business system, it is safely partitioned. The key business is network-specific, the horizontal boundary is unidirectionally isolated, the vertical boundary is encrypted and authenticated, the application system is free of malware, and the operating system has no malicious backdoor. Malicious chips, the main chip has no malicious instructions. "Independence and security control is an inevitable trend in the development of information technology in the power industry. On this basis, it is necessary to strengthen the construction of the information security system in an all-round way and strengthen the structural top-level design of information security. Professional security vendors must also work with the power industry. The business and informationization process of the enterprise is closely combined, and tailored information security solutions can be tailored to meet their actual security needs based on their industry information and business characteristics.†Wang Jianbin said. Currently, various professional security vendors are developing solutions for their customers. Take the China Electric Power Science Research Information Security Laboratory as an example, it launched two platforms. Its server platform, including PCI-E interface trusted password card, trusted software base, trusted management center and other technologies, can be applied to grid dispatch control system and high security level information system; embedded platform, with embedded platform dedicated Trusted chips, trusted distribution network terminals, public network communication security gateways and modules. Data business can try three steps In addition to establishing an active defense system, the information security of the power industry is also reflected in how to realize the controllability of massive equipment, the number of systems, the large amount of data, and the inevitable existence of information chimneys and information islands, how to realize the vertical development and horizontal penetration of information systems. How to dig out value information from big data in the power industry is a few hurdles in the process of power informationization. Zheng Chaode, director of Inspur Group, gave his suggestion. He said: "You can try three steps. First, implement the 'upper cloud', which is the technology based on cloud computing, without changing the business architecture. Means to move the traditional information business to the cloud; the second step is to integrate the power data and rely on the open data platform to horizontally open, clean, and classify the data of each business module; the third step is to integrate the organization data. Introduce Internet data, and realize business innovation through big data analysis and mining.†Gao Wei, head of Huawei Technologies Co., Ltd., said: “In the future, in the construction of fully connected power grids, smart power equipment, smart homes, and charging piles will be faced. Access challenges for massive intelligent power terminals such as distributed energy. A single access method cannot meet the needs of different forms and ubiquitous device access, and build a wired and wireless coverage and a full-station effective terminal communication access network. Achieve comprehensive intelligent identification of information in all aspects of power production, transportation, consumption, and management, and fully sense the operating status of the power grid This is the first foundation for a fully connected grid.†“No matter what solution is customized, the future smart grid is a highly integrated power information physics system whose ultimate goal is to make future physical systems more mobile and autonomous. , reliability and safety.†Gao Kunlun further stressed that it is necessary for power information companies to do a good job together.
