Cybersecurity defense practices for smart factory (Part 2)
Due to the characteristics of industrial production, there are bound to be risks in the production process. From the input of raw materials and various cutting and grinding that produce physical and chemical changes during the automated process, to the output of products and the disposal of remaining waste, negligence of cybersecurity in any link may affect the manufacturing process and cause significant losses.

Industrial control security standard and practice - A brief overview of the IEC62443
On December 23, 2015, the Ukrainian power grid was attacked by a hacker, resulting in a blackout in the Ivano-Frankivsk region. This is the world’s first large-scale power outage caused by a hacker attack, and has caused all parties to attach great importance to the cybersecurity threats of critical infrastructure.

Minimizing threat risk with establishing industrial control cybersecurity process and obtaining international verification
In the past few months, there have been many major domestic cybersecurity incidents . During May, the large petrochemical company and the semiconductor assembly and test factory were infected with ransomware. During June, the automation equipment factory was infected with ransomware, and the PCB manufacturer was infected with viruses. In July, the major wearable device manufacturer was also attacked with ransomware. At the same time, more and more malicious programs designed for industrial control equipment have been exposed, such as EKANS (Snake) targets GE's Historian, LogicLocker targets PLC, and Triton targets Schneider's TriconexSIS controller.

Cybersecurity defense practices for smart factory (Part 1)
In recent years, the government has been vigorously promoting Industry 4.0, also known as Smart Factory. Its focus is on the intelligence of the production line, which needs to integrate existing IT and OT technologies, and use numerous IoT devices, so as to meet the rapidly changing needs of customized manufacturing. In order to optimize the production process, it is an inevitable trend to adopt and deploy a large number of cybersecurity equipments.

Intelligent manufacturing faces security challenges and opportunities in the coming IIoT era
With the advancement of artificial intelligence (AI) technology, intelligentization has become the main theme of technology development in the 21st century. The core technology of intelligent manufacturing is the Internet of Things (IoT) technology and the Cyber-Physical System (CPS). By combining big data analysis, artificial intelligence, cloud computing and other technologies, intelligent manufacturing is trying to intelligentize every step of the production process, thereby achieve the customized business goal to meet the small and diverse market demand.
