[0002] Illegal external connection of telecontrol devices is an extremely serious risk in the field of industrial network security. As a key part of the automation control system in the power, chemical and other industries, telecontrol devices undertake important functions such as data collection and remote control command transmission. Once an illegal external connection occurs, that is, a connection is established with an unauthorized external network or device, which may lead to a variety of serious consequences. From the perspective of information security, malicious attackers can use this to break through network protection and steal sensitive data in the system, such as production process parameters, user information, etc., damaging the company's commercial secrets and reputation. In terms of industrial production, illegal external connections may cause incorrect control command input, disrupt the production process, abnormal equipment operation, and even cause large-scale production stoppage accidents. For example, in the power system, it may lead to incorrect power generation dispatching instructions, affecting the stability of power supply. In addition, it may also open up channels for the invasion of network viruses and malware, which will spread within the system, further damage network infrastructure and applications, bring immeasurable losses to enterprises, and seriously threaten the safety and stability of industrial production.
