Hello Securing Things Community,

This is Part-2 of a multi-part series on ISA/IEC 62443 standards overview - and will be expanding upon the 4 main groups and the series of documents, their purpose, security levels, expand IACS cybersecurity lifecycle phases, individual and product certifications.

In ISA/IEC 62443 Standards Overview?Series - Part 1, we covered, introduction & background about the standards series, basics around:

• key stakeholders, IACS roles & responsibilities,
• 4 groups of standards requirements,
• 3 phase IACS Cybersecurity Lifecycle, and
• introduce you to certification options from Supplier and Product, Asset owner Certifications from #ISASecure (Securing Things is a supporting member of ISASecure), and
• cybersecurity certifications for individuals by #ISA.

{Quick check - Part 1 included a tip to remember the 4 groups in the standards series with the help of a short phrase; see if you can recall, without giving a peep at Part 1. Did you? if not go ahead and click the Part 1 link above and checkout the code snippet like this for the tip...}. :-) hope that'll help you remember.
