Understanding the ISA/IEC 62443 Standards for Industrial Cybersecurity

The ISA/IEC 62443 series of standards defines international requirements and processes for implementing and maintaining electronically secure Industrial Automation and Control Systems (IACS).

These standards set best practices for security and provide a framework to assess the level of cybersecurity performance. Their approach to cybersecurity is holistic, bridging the gap between operations and information technology, as well as between process safety and cybersecurity.

The ISA/IEC 62443 standards establish cybersecurity benchmarks across all industry sectors that use IACS, including building automation, electric power generation and distribution, medical devices, transportation, and process industries such as chemicals and oil & gas.
