The CC-Link Partner Association (CLPA) has established a working group on industrial Ethernet security, with the aim of providing a guideline document for users looking to build secure networks around the open gigabit Ethernet CC-Link IE technologies. In particular, the document will cover strategies for users adopting the CLPA’s Seamless Message Protocol (SLMP) and CC-Link IE Field Basic where general IP communication is used for both cyclic and transient communications.
While the industry is taking steps to make hardware more secure, the CLPA felt that more could be done to address deficiencies in network security without compromising the requirements of the plant floor.
Hence the decision was taken to form a security working group that will build on the network security strategies defined under IEC 62443, which focuses on industrial automation and control systems. The standard is a comprehensive framework that addresses all key aspects of securing plant systems, such as how to establish a security programme, use cases, technical requirements and so on.
