面向感算控智一体化融合的工业互联网新型犘犔犆安全增强： 趋势与展望

Programmable Logic Controllers (PLCs), a key infrastructure in the industrial control dornain, have long been a primary target for attacks on Industrial Internet and Control Systems due to the lack of inherent security architecture in their initial design. With the rapid development of Industry 4. 0 and intelligent manufacturing technologies, traditional PLCs are evolving into Intelligent Programmable Industrial Controllers (IPICs), integrating functions such as perception acquisition, data computation, real-time control, intelligent decision-making, and network communication to meet the technical demands of automation, networking, and intelligence in the Industrial Internet. However, the convergence of Information Technology (IT) and Operational Technology (OT), along with the integrated heterogeneous functional loads, further exacerbates the security challenges faced by IPICs. This paper aims to research the security enhancement of the new type of Industrial Internet PLCsG. e., IPICs), especially revealing the application prospects and future development directions of embedded virtualization isolation technology in building the inherent security architecture of IPICs. Specifically, it first systematically analyzes the security threats faced by PLCs and the existing security protection technologies; then it introduces embedded virtualization isolation technology with real-time characteristics, and proposes a Solution to reconstruct the basic security architecture of IPICs from the perspective of inherent security; subsequently, it follows the virtualization isolation concept and designs a security enhancement architecture for anomaly detection and response in IPIC by integrating heterogeneous security loads through virtualization, discussing the technical challenges faced in the actual deployment of industrial Systems; finally, it provides a forward-looking perspective on the future development trends of IPIC security enhancement.
