Ideal Solutions Derived from Field Surveys 'Cybersecurity Countermeasures for Next-generation Plants'

摘要

The Industrial Internet of Things (IIoT) has increasingly been used in business. Various systems are connected to networks, and many devices are connected to these systems via networks. As the IIoT spreads worldwide, not only devices but also communications between plants in Japan and overseas will connect beyond the boundaries of companies. However, although network-based devices connected via IIoT create new business opportunities, networking also brings new threats and challenges due to the connectivity itself. Yokogawa's IT infrastructure for the next-generation factory strives to meet the requirements of "safe and secure operation," "flexible and scalable system," and "quick information-gathering and correct decision-making" to build the optimal factory for the IIoT environment. This paper describes the key points of next-generation plant network security and Yokogawa's security measures for control systems based on plant IT network issues, verification of the latest technology, and installation and operation in actual plants.
