[cabfpub] [EXTERNAL] Forbid DTPs from doing Domain/IP Ownership Validation ballot draft

Gerv, I’m late to the discussion on this.  By can you start at the beginning, and explain why you believe DTPs should not be permitted to perform domain validation under any circumstances?

As a refresher, here is the definition of a DTP in the BRs: “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.”

I’m not speaking from an Entrust use case, but I can imagine there could be cases where the CA has no one on staff who can read or interpret certain languages and alphabets (Russian Cyrillic, Greek, Arabic, Chinese, Japanese).  They want to do a WhoIs lookup, but can’t read or interpret what they see.  This could be a perfect situation for using a DTP for domain verification.

Clearly the work of all DTPs should be audited, and the DTP part of the audit should roll up somehow into the issuing CA’s audit.  I know that can be complex (and under current rules, may be hard for browsers to monitor and feel confident they understand the ENTIRE network of DTPs, etc. used by the CA under each root).  But it can be done.

I’m not personally familiar with the current complexity of making sure all DTPs are covered by a CA’s audit.  But wouldn’t it make sense to spend time working on the audit completeness problem (which is important in any case) and not forbid use of DTPs for domain verification?

Subject: [EXTERNAL][cabfpub] Forbid DTPs from doing Domain/IP Ownership Validation ballot draft

Hi everyone,

Here's a draft of a ballot to forbid DTPs from doing Domain Validation, as discussed at the F2F. Again, this is early text, so comments on both the approach and the wording are very welcome.

Is an Enterprise RA a subset of Delegated Third Party, or a different thing? The BRs seem a little unclear on this. I think they are a separate thing, but there are some bits of wording this ballot modifies or removes that suggest that they are a subset. Comments?

Gerv

Ballot XXX - Forbid DTPs from doing Domain/IP Ownership Validation
Purpose of Ballot: At the moment, CAs are permitted to delegate the process of domain and IP address validation. However, permitting such delegations is problematic due to the way audits work - the auditing of such work may or may not be required and, if it is, those audit documents may not make it back to root programs for consideration. Although the audit situation also needs fixing, domain validation is an important enough component of a CA's core competencies that it seems wiser to remove it from the larger problem and forbid its delegation. The purpose of this ballot is to ensure that CAs or their Affiliates are always the ones performing domain/IP address ownership validation for certificates that CA is responsible for.
The following motion has been proposed by Gervase Markham of Mozilla and endorsed by XXX of XXX and XXX of XXX:

-- MOTION BEGINS --

1) In section 1.3.2 of the Baseline Requirements, replace the following sentence:



"The CA MAY delegate the performance of all, or any part, of Section 3.2 requirements to a Delegated Third Party, provided that the process as a whole fulfills all of the requirements of Section 3.2."



with:



"With the exception of sections 3.2.2.4 and 3.2.2.5, the CA MAY delegate the performance of all, or any part, of Section 3.2 requirements to a Delegated Third Party, provided that the process as a whole fulfills all of the requirements of Section 3.2."



2) In sections 3.2.2.4 and 3.2.2.4.11 (if still present in the text at the time the ballot passes), replace the following text:



"either the CA or a Delegated Third Party"



with:



"the CA"



3) In section 3.2.2.4.6, remove the words "or Delegated Third Party".



4) In section 8.4, remove the paragraph beginning: "If a Delegated Third Party is not currently audited...".



5) In section 8.4, replace the following text:



"If the CA is not using one of the above procedures and the Delegated Third Party is not an Enterprise RA, then"



with:



"For Delegated Third Parties (but not Enterprise RAs)".
