71.3. Report from SC 22 (Convenor)

This is the only significant issue for this meeting.

The SC 22 committee manager has reported that ISO rejected the free availability of TR 24772-1:2019, TR 24772-2:2020 and 24772-3:2020 because they are technical reports and not technical standards. This leaves us no choice but to reissue the documents as international standards.

SC 32 has been through this process and has had no difficulty gaining free availability for documents that were freely available TR's, and reissued as IS's.

Erhard proposes that we do not attempt to make parts 1, 2 and 3 all international standards at the same time, but to rather quickly do part 1, and if successful and accepted by ISO as freely available, then to make the other documents into IS's.

The process for making TR 24772-1 n(and the others) into IS's is to attach the upgraded document to a new work item proposal (NWIP) with a simultaneous CD ballot. Once those complete it is followed by a DIS ballot and publication (if no negative comments – otherwise an FDIS is also needed).

The major difference between a TR and an IS is that an IS has normative text and that organizations can claim conformance to it. With all of the guidance that these TR's provide, we surely cannot dictate that every organization implement every recommendation. Therefore, I propose that we add a sub-sub-clause in clause 5 that tells organizations how to claim conformance. The instructions will demand an evaluation of the space that the product or system is intended to fill, determine risks and attack surfaces, and develop a plan to mitigate the risks and minimize the attack surfaces.

In order to mitigate risks and minimize attack surfaces, the organization studies the guidance provided in the relevant 24772 document(s) and decides what guidance must be implemented in the project, and then develops design guides programming guides to meet their requirements.

Then we leave the rest of the document alone, except to reference relevant process documents, such as IEC 61508 series (functional safety standards), the ISO/IEC 27000 series of safety standards, and relevant software engineering standards (possibly ISO/IEC 12207).
