Industrial Ethernet security check: Implement security in project design

摘要

Security for an industrial Ethernet network is essential. What was once strictly an IT or "office network" issue has now become vital for plant managers and control engineers. Hacking, unauthorized access, and disruption caused by unwanted traffic in industrial control and automation environments can cause downtime, program failures, and health and safety problems. The Stuxnet worm is only one example of the challenges emerging as supervisory control and data acquisition (SCADA) and control systems receive more attention from the hacking and malware community.
