It’s been over a year since the NIST Cybersecurity Framework and ISA-62443-3-3 were published, ISA-62443-2-1 has been out for almost 5 years, and ISO/IEC 27001 & 27002 have been out for nearly a decade. NIST has already started their process for revisions, ISA is actively working to overhaul 62443-2-1, and ISO/IEC just published a major revision to their standard. In addition to these cross-domain standards, there are a multitude of local and sector-specific standards as well. As a consultant, we are often asked to use one of these as a baseline to help our customers generate an ICS cyber security program. This presentation will discuss some of the strengths and weaknesses of these different standards and the effort to integrate them into a realistic set of ICS cyber security program requirements.
