With increasing marketization and intensifying competition, the development trend of industrial equipment enterprises is to utilize advanced information and network technologies to continuously improve the automation and networking of industrial equipment, thereby reducing the workload of industrial equipment users and improving the management efficiency of industrial equipment managers.
However, like two sides of a coin, with the deep integration of informatization and industrialization, networked management operations have also led to a more complex range of attack sources, diversified attack objectives, and continuous attack processes for viruses and Trojans targeting industrial control systems.
If we carefully analyze each level from industrial terminal equipment to industrial control system architecture, the security issues unique to the field of industrial automation will bring the following risks: the source code in the terminal equipment is copied or stolen, causing years of hard work by industrial control equipment companies to go to waste; the embedded software is stolen or copied, leading to the misuse of the terminal equipment; due to identity theft, information is read without the system's knowledge; data in the system is invaded or tampered with, and the data of the forged and copied equipment is entered into the system under false names, resulting in data disaster.
According to statistics from RISI, a leading industrial security incident database, hundreds of attacks targeting industrial control systems occur globally each year. Since 2001, the widespread use of common development standards and internet technology has led to a significant increase in attacks against industrial control systems, including viruses and Trojans. These attacks result in overall control system failures and even serious security incidents, causing severe consequences for personnel, equipment, and the environment. Therefore, the need for information security for industrial control systems has become even more urgent.
Currently, the Internet of Things (IoT) has enabled the fusion of the physical and analog worlds, and the digital and virtual worlds—the so-called "Industry 4.0." However, disproportionately, China's industrial control system (ICS) sector faces significant security and reliability issues. The increasing complexity, IT integration, and generalization of ICS systems have exacerbated security vulnerabilities. Numerous facts demonstrate that only by being proactive and prepared can we ensure the healthy and stable operation of industrial control systems. This necessitates that enterprises actively adopt countermeasures, such as CodeMeter's integrity protection measures, to implement new protection strategies for ensuring the security of industrial automation systems.
