[Servercert-wg] Proposal to update logging requirements

Hi Tobias, 

I can only share our side of the discussion, as done in the first email I sent out. However the logging of all OCSP requests was certainly part of this. Other than that, the discussion was more in general around what it may entail without going into specific points on what should or should not be included. 

If CABF members want to bring forward specific items or ideas they believe should be covered in here, on top of the proposed changes, then lets have a discussion on that and see how detailed we can get! 

As indeed you have brought forward an idea: Yes I think having logins (and unsuccessful login attempts) logged, would indeed be useful. 

Are there any other items that you would like to see reflected?

Thank you! I can certainly agree that, without any context, a hypothetical
requirement "Record all firewall and router activities." will easily lead
to nonsensical results depending on the definition/interpretation of
activities. I can also agree that, even with the context of 5.4.1, it may
not necesarily be very clear what the interpretation should be.

I was just hoping that getting a brief insight into the point of
discussion that you had come up might be helpful in delineating more where
the line should be, and then how to express it in 5.4.1.

however look like they are falling a bit short. There are many more types
of "activities" that I would think should be encompassed by 5.4.1, too
many to give a list. But to single one out just to illustrate my point, I
think that logins to the router's/firewall's management interface are a
kind of "activity" that would be very useful to have covered by 5.4.1.

If you could provide any insight into how differing interpretations are
clashing in practice, it would help me a lot, and I would really
appreciate it.
