Your Guide to Cybersecurity Standards

The ISA Global Cybersecurity Alliance’s Advocacy and Adoption work group has overseen the development of a brand new, user-friendly overview of the ISA/IEC 62443 series of standards. “Quick Start Guide: An Overview of the ISA/IEC 62443 Standards” answers often-asked questions about these standards, including:

  • Why is the series of standards important? What are the benefits of using the standards?
  • How are IT and ICS systems different?
  • Which documents are part of the series and how can I navigate them to find what I need?
  • Where can I find the current recommendations around patch management?

In addition to providing a high-level view of the objectives and benefits of the series, the guide also identifies specific standards documents that are applicable to various roles within the security environment, including asset owners, automation product suppliers, system integrators, and maintenance providers.
