I have always though that safety and security are two sides of the same coin. Often it is just a difference of emphasis or wording but the requirements are very similar if not the same.

The trouble is “cyber security” is the new buzzword so we need a standard for it….. Surely it is better build on 61508 for something that is both safe and secure?  

Or do you want something that is secure but unsafe? J

Where can I find details of the content of IEC 62443, and of the IEC workgroup?

There is currently an IEC workgroup on what to do with IEC 61508 and cybersecurity (IEC 62443). The topic is thus not ignored.
