On the CA/Browser Teleconference last Thursday, the members discussed pending 
Ballot 218, which would eliminate domain validation method 1 (WhoIs lookup, BR 
3.2.2.4.1) as of August, 2018.  Google indicated it was not satisfied with an 
August 2018 implementation date, and might impose a March 2018 date on its own 
(through the Google root program) ending the ability to use Method 1 for domain 
validation as of that date.

We would like to ask Forum members, including Google, for a little more time to 
discuss this issue, including possible amendments to Ballot 218 that might 
satisfy everyone's concerns.  Some possible ideas for amending Method 1 (which 
we can develop further in our next meeting) could include the following:


  *   Strengthen Method 1 by adding more details match the Applicant and the 
domain Registrant using name and a unique identifier.
  *   Require the CA also to send a notice of domain validation to the 
Registrant, allowing the Registrant to have the certificate revoked if the 
validation is not authorized.
  *   Eliminating Method 1 for DV and OV domain validation, but allowing Method 
1 to be used for EV validation. The EV validation process already includes two 
steps to confirm the authority of the Applicant Representative to order the 
certificate - including a call to a second person at the organization to 
confirm that the Applicant Representative has authority to request the 
certificate.  (EVGL 11.8)
  *   Ballot 218 will require revalidation of 100% of domains previously 
validated using Method 1 for issuance starting 1 August 2018 (if Google acts 
unilaterally to prohibit use of Method 1 by March, this revalidation deadline 
could be March 2018).  We suggest Ballot 218 should allow reuse of domain 
validation data for the normal period allowed by BR 4.2.1, as is the Forum's 
standard practice. This will allow CAs to change processes, implement/extend 
automation and train customers on alternative validation methods.
  *   Finally, the elimination of Method 1 will have a significant impact not 
only on CAs (some of whom are Forum members, but many of whom are not and are 
unaware of this discussion), but more importantly on major certificate users 
including enterprises and governments who often prefer Method 1 for validation 
of their domains. Therefore, we ask for more time for both discussion and 
implementation so both CAs and website owners can have a more graceful 
transition to whatever new rules we ultimately adopt.

The Forum will be meeting in approximately 5 weeks at our Face to Face meeting 
in Herndon - this is a complex topic which would benefit from a thorough 
discussion at that meeting to try to reach a sensible solution.  We should 
continue discussion on this list, but let's wait until the F2F meeting occurs 
to reach a final conclusion that can be implemented without unnecessary 
disruption to the security ecosystem.

Thanks,

Bruce.

Subject: [EXTERNAL][cabfpub] Ballot 218 version 2: Remove validation methods #1 
and #5


Ballot 218 version 2: Remove validation methods #1 and #5

Purpose of Ballot: Section 3.2.2.4 says that it "defines the permitted 
processes and procedures for validating the Applicant's ownership or control of 
the domain."  Most of the validation methods actually do validate ownership and 
control, but two do not, and can be completed solely based on an applicant's 
own assertions.

Since these two validation methods do not meet the objectives of section 
3.2.2.4, and are actively being used to avoid validating domain control or 
ownership, they should be removed, and the other methods that do validate 
domain control or ownership should be used.

The following motion has been proposed by Tim Hollebeek of DigiCert and 
endorsed by Ryan Sleevi of Google and Rich Smith of Comodo.

-- MOTION BEGINS -

This ballot modifies the "Baseline Requirements for the Issuance and Management 
of Publicly-Trusted Certificates" as follows, based upon Version 1.5.4:

In Section 1.6.1, in the definition of "Domain Contact", after "in a DNS SOA 
record", add ", or as obtained through direct contact with the Domain Name 
Registrar"

In Section 3.2.2.4.1, add text at the end: "For certificates issued on or after 
August 1, 2018, this method SHALL NOT be used for validation, and completed 
validations using this method SHALL NOT be used for the issuance of 
certificates."

In Section 3.2.2.4.5, add text at the end: "For certificates issued on or after 
August 1, 2018, this method SHALL NOT be used for validation, and completed 
validations using this method SHALL NOT be used for the issuance of 
certificates."

After Section 3.2.2.4.10, add following two new subsections:
"3.2.2.4.11 Any Other Method

This method has been retired and MUST NOT be used.

3.2.2.4.12 Validating Applicant as a Domain Contact

Confirming the Applicant's control over the FQDN by validating the Applicant is 
the Domain Contact. This method may only be used if the CA is also the Domain 
Name Registrar, or an Affiliate of the Registrar, of the Base Domain Name.

Note: Once the FQDN has been validated using this method, the CA MAY also issue 
Certificates for other FQDNs that end with all the labels of the validated 
FQDN. This method is suitable for validating Wildcard Domain Names."

In Section 4.2.1, after the paragraph that begins "After the change to any 
validation method", add the following paragraph: "Validations completed using 
methods specified in Section 3.2.2.4.1 or Section 3.2.2.4.5 SHALL NOT be 
re-used on or after August 1, 2018."

-- MOTION ENDS -

For the purposes of section 4.2.1, the new text added to 4.2.1 from this ballot 
is "specifically provided in a [this] ballot."

The procedure for approval of this ballot is as follows:

Discussion (7+ days)
  Start Time: 2017-01-22  21:30:00 UTC
  End Time: Not Before 2017-01-29 21:30:00 UTC

Vote for approval (7 days)
  Start Time: TBD
  End Time: TBD
