Dear CESG Colleagues,

At the July 18 meeting I agreed to take a look at the spreadsheet that Peter prepared and to check the PIDs listed therein against the latest MAL document. Essentially to perform a review of the review. Accordingly, please see the attached spreadsheet.

My conclusion is that, on balance, there does indeed need to be some revision of the document prior to agency review. Having said that, I will note, that as I was on vacation and did not participate in the vote, these are of course not any kind of conditions but rather hopefully some assistance in sorting out the PIDs that were recorded for the vote.  To be more specific, my findings can be summarized as:

  1.  Terminology is used in multiple senses in different parts of the document and/or not defined in the terminology section; this tends to lead some definitions that are circular (e.g., "...attribute extends 'Attribute'...")
  2.  The PICs proforma is not properly stated (see comments in the spreadsheet)
  3.  It seems that some sort of requirements on the transport layer should be stated
  4.  Cybersecurity needs to be addressed

I will also note there are some of the PIDs where I think Peter stated some things incorrectly and/or I did not really see the issue.  Perhaps this is a case where the definition of success is getting everybody angry at you :-)

Best regards,

Ps, the spreadsheet has also been uploaded to the CWE space used for the July 18 meeting.

Hello Peter,

As you may recall, I volunteered to take a look at the MO MAL Agency Review CESG Poll PIDs and check them against the latest MAL document.  I see the presentation, dated July 11 in the CWE for CESG, but I do not find the spreadsheet there.  Can you please either send or (probably better) post the spreadsheet?  Thank you.

Best regards,
