Somehow this has become very complex, and I have to say I don’t understand what 
you are asking.  I thought “the CA’s audits” was pretty clear and covered 
everything.

I will leave it to Gerv to choose whatever wording he prefers.

Kirk,

Would you agree that your proposed wording introduces the issue that is avoided 
by the current wording, which is that a CA can easily misread this to suggest 
that, say, if the DTP is covered under the "WebTrust for CAs" audit, it need 
not necessarily be covered under the "WebTrust for CAs - SSL Baseline w/ Net 
Sec" - even though the activities of the DTP mean it should?

I understand your goal with the plurality, but the problem is that it 
introduces an ambiguity as to the necessity of the relevant audits. Hopefully 
you can see why more specificity helps avoid this otherwise unnecessary 
ambiguity (that being covered under 'an' audit is sufficient).

Similarly, consider the inverse - if there is a DTP who performs, say, 
datacenter activities, do you believe there are principles and criteria 
captured in the "WebTrust for CAs - SSL Baseline w/ NetSec" that would be 
relevant/necessary for audit? Or would you agree that, depending on the scope 
and role of the datacenter provider, it may be that the only criteria and 
controls are captured within the "WebTrust for CAs" criteria.

Obviously, I use a bias towards WebTrust here, if only because the split is 
more obvious and apparent than the ETSI equivalents, and hopefully, it's one 
you're more familiar with, thus making it easier to see the problems with the 
proposed wording change.

Gerv, first thanks for doing this – it helps.

Second – I’m still thinking about the text of the addition.  You propose “and 
whose activities are not within the scope of the appropriate CA audits”.  We 
discussed briefly at the meeting, and I know what you mean by the phrase and 
agree with it.

The definition has two references to “the CA”, so I’m wondering if we should 
just use “the CA’s” in the new language you would add.  So the change would be 
as follows:

Delegated Third Party: A natural person or Legal Entity that is not the CA, and 
whose activities are not within the scope of the appropriate CA’s audits, but 
is authorized by the CA to assist in the Certificate Management Process by 
performing or fulfilling one or more of the CA requirements found herein.
What do you think?  I worry that including “appropriate” could create potential 
ambiguity as to which audits are the “appropriate” ones for this definition.  
Saying “the CA’s audits” should cover all the CA’s audits.  (If the DTP’s 
activities are not examined in a particular audit because of the nature of the 
audit, they are still within the “scope” of that audit.)

Subject: [EXTERNAL][cabfpub] Updating DTP definition


Before we move the ballot forbidding DTPs from doing domain validation, we need 
to update the definition of DTP to make sure it excludes people and activities 
covered by the CA's audit.

The current definition is:

Delegated Third Party: A natural person or Legal Entity that is not the CA but 
is authorized by the CA to assist in the Certificate Management Process by 
performing or fulfilling one or more of the CA requirements found herein.

Here is a proposed updated definition:

Delegated Third Party: A natural person or Legal Entity that is not the CA, and 
whose activities are not within the scope of the appropriate CA audits, but is 
authorized by the CA to assist in the Certificate Management Process by 
performing or fulfilling one or more of the CA requirements found herein.

Does

Gerv
