On the CA/Browser Teleconference last Thursday, the members discussed pending Ballot 218, which would eliminate domain validation method 1 (WhoIs lookup, BR 188.8.131.52.1) 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.

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 184.108.40.206 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 220.127.116.11, 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 18.104.22.168.1, 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 22.214.171.124.5, 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 126.96.36.199.10, add following two new subsections:
"188.8.131.52.11 Any Other Method
This method has been retired and MUST NOT be used.
184.108.40.206.12 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 220.127.116.11.1 or Section 18.104.22.168.5 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."
