COMPLIANCE

Applying the ISA/IEC 62443 Standards for IACS Security

What Are the ISA/IEC 62443 Standards?

The ISA/IEC 62443 series of standards was developed by the ISA99 Committee and the IEC Technical Committee 65/Working Group 10 to define requirements and processes for implementing and maintaining electronically secure IACS. These standards set best practices for security and provide a way to assess the level of security performance.

Maintaining compliance with ISA/IEC 62443 can help reduce the likelihood of cyberattacks and help avoid serious regulatory, financial and safety consequences while ensuring that operations are achieving comprehensive levels of ICS and cyber-physical security.
