Hollysys' safe and trustworthy DCS control system uses the controller K-CU11 for the K series large-capacity trusted controller module, which adopts advanced PowerPC architecture high-performance main processor and security components based on national cryptography algorithm, and has the security functions of static trusted start and dynamic trusted measurement.
The industrial control system represented by DCS is the key equipment to realize the digitalization, networking and intelligence of the manufacturing industry. The core control equipment and system is the command brain, control center and security center of major projects in the fields of modern electric power, petrochemical, metallurgy, national defense, etc., and is also an important foundation for national economy, social operation and national security. With the emergence of new technologies such as industrial Internet and cloud computing, industrial control systems have gradually evolved from closed and isolated systems to open interactive systems, which has brought new challenges to information security.
Traditional control system defense mainly uses firewalls, patches and other means to strengthen security on the basis of blocking, isolation and vulnerability analysis. However, this passive defense method has been difficult to resist the rapid development of cyber attack technologies and segments, and various new and unknown threats have exacerbated this phenomenon. Once the intrusion attack breaks through the traditional passive defense, it will seriously threaten the safe operation of the industrial control system and even cause serious accidents. In this context, Hollysys took the lead in releasing a new generation of secure and trustworthy DCS control system, which has endogenous security protection capabilities compared with traditional control systems.
Key innovations
The secure and trusted DCS control system is designed based on the trusted computing technology system, and is equipped with a secure and trusted control system with active immunity capability for life cycle network security, with embedded trusted computing endogenous security technology architecture and static trustworthiness
Key core technology innovations such as start-up, life-cycle trusted protection system, firmware trusted upgrade technology, and national secret secure communication.
In the start-up stage of the secure and trustworthy DCS control system, a trusted chain transmission model is constructed to ensure trusted start-up, and a dynamic measurement model is established during operation to ensure the safe and trustworthy operating environment of the control system and realize trusted protection throughout the life cycle.
The secure and trustworthy DCS control system has the static trusted start function, the active defense function based on the dynamic measurement of the quadruple, and the firmware trusted upgrade function.
Defenses
Whether the bootloader, operating system, application code and data loaded by boot loading have been tampered with, and are protected by the static trusted boot function;
In the operation stage, the control system is maliciously attacked and causes abnormal operation, and the dynamic trust measurement function is used to defend it.
In the upgrade stage, the correctness of the firmware source file, the interception of malicious upgrade behaviors, and the encryption of the communication process are all guaranteed by the firmware trusted upgrade function.
