1) Power system computer network equipment is not unified. Power system automation is an important field of application of modern computer control technology. The main problems of automation in this period are the lack of industrial standards in system structure, function and communication protocol, and the equipment of different manufacturers can not be interconnected; The communication between computers and devices is generally a star-shaped point-to-point connection. Low-speed serial port and parallel port communication are mainly used, which leads to poor real-time performance of the system and poor flexibility of equipment configuration.
2) Lack of management norms. So far, a unified and authoritative power information security management standard has not been established, which conforms to the characteristics of the power industry.
3) loopholes in the computer operating system of the power sector. No matter which operating system is used. There are a lot of known or unknown vulnerabilities, which can lead intruders to gain administrator rights and can be used to attack the whole network information system.
4) The information security system has not been established. The lack of security awareness of computer information network, perfect computer data backup system, weak identity authentication, and the extensive use of isolated local area networks to form wide area networks in the past have greatly improved the overall security of the network.
