ISA/IEC 62443

ISA/IEC 62443 Conformance Services

The ISA/IEC 62443 series of standards outline the requirements for ensuring secure industrial automation and control systems (IACS). At a bare minimum, these standards define security levels that arise from deploying security and operational visibility and control measures to address the gap between process safety and cybersecurity as well as ICS and OT systems and IT.

IEC 62443 comprises nearly 14 standards with each covering a specific purpose. To move towards IEC 62443 compliance, enterprises need to take measured steps in areas such as vulnerability management, network and operational visibility, network segmentation, network monitoring and threat detection. IEC 62443 presents a way for enterprises to ramp up their security maturity in key areas. In fact, the IEC 62443 journey can be extrapolated to go well past compliance into the proactive security management realm.
