…(#475)
- Clarify the use of third-party DNS recursive resolvers
Add a sentence to BRs Section 3.2.2.4 clarifying that the use of DNS recursive resolvers which are operated outside the CAs audit scope qualifies as use of a Delegated Third Party, which is forbidden for domain control validation.
- Include clarifications for Domain Contact and IP Address Contact
These are clarifications that the CA must obtain information to be used in the Domain Validation process directly from Domain Name Registrars or IP Address Registration Authorities. CAs must not use third-party services outside their audit scope.
Add the same DNS clarification to 3.2.2.5
Simplify references to Domain Contact
Consolidate new text into 3.2.2, and cover 3.2.2.8 CAA
Add effective date for CAA
Improve effective date table
Improve 1.3.2 effective date

- Created at May 20, 2024, merged on Jun 27, 2024baseline-requirementsThere have been numerous compliance incidents publicly disclosed by CAs in which they failed to comply with the technical requirements described in standards associated with the issuance and management of publicly-trusted TLS Certificates. However, the industry has developed open-source tools, linters, that are free to use and can help CAs avoid certificate misissuance. Using such linters before issuing a precertificate from a Publicly-Trusted CA (pre-issuance linting) can prevent the mis-issuance in a wide variety of cases.

Summary: This is the third version of SC-067, which intends to add “Multi-Perspective Domain Validation” and “Multi-Perspective CAA Checking” (together referred to as “Multi-Perspective Issuance Corroboration”) requirements to the CA/Browser Forum TLS Server Certificate Baseline Requirements.
This Pull Request:
- compares the latest version of SC-067 (Version 3) against Version 2.0.4 of the TLS Server Certificate Baseline Requirements.
- addresses issues and comments made against Ballot Version 2 of this effort during Server Certificate Working Group Public Discussion. A separate branch was created to help make changes across versions of the document clear to readers.

This ballot updates the TLS Extended Validation Guidelines (EVGs) by removing the exceptions to
policyQualifiersin section 9.7, to align them with the Baseline Requirements (BRs).As result, this ballot changes
policyQualifiersfromMUSTtoNOT RECOMMENDEDas stated in the TLS Baseline Requirements, resolving a discrepancy introduced by Ballot SC-62v2 between section 7.1.2.7.9 Subscriber Certificate Policies of the BRs and the Additional Technical Requirements for EV Certificates in the EVGs.The following motion has been proposed by Paul van Brouwershaven (Entrust) and endorsed by Dimitris Zacharopoulos (HARICA) and Iñigo Barreira (Sectigo).

Summary: This is the first version of SC-067, which intends to add “Multi-Perspective Domain Validation” and “Multi-Perspective CAA Checking” (together referred to as “Multi-Perspective Issuance Corroboration”) requirements to the CA/Browser Forum TLS Server Certificate Baseline Requirements. Official public discussion is expected to begin the week after CA/Browser Forum F2F 61.
This Pull Request:
- compares the latest draft of SC-067 against Version 2.0.2 of the TLS Server Certificate Baseline Requirements.
- addresses issues and comments made against draft Version 2 (pre-ballot) (clean) of this effort. A separate branch was created to help make changes across versions of the document clear to readers, and due to owner of the earlier versions being on leave.

Summary of recent updates:
- Establishes requirements for the use of recursive DNS resolvers for remote Network Perspectives following discussions related to Ballot SC-070.
- Adds flexibility regarding how Network Perspectives may be operated to corroborate domain control validation.
- Permits re-use of MPIC CAA quorum for subdomains under certain conditions.
- Clarifies that Onion Names are outside of scope and exempt from MPIC requirements.
- Moves CAA-related requirements from Section 2.2 into Section 4.2.2.8 to address issue 466.
- Shifts back required implementation dates.

Add a paragraph to BRs Section 3.2.2 clarifying that all Domain Control Validation DNS queries must be conducted by the CA itself, without the use of third-party recursive resolvers. Similarly clarify that looking up information for Domain Contacts and IP Address Contacts must also be done without third-party services.
Require that CAA checks be performed by the CA itself, and not delegated to a third party.

In light of https://bugzilla.mozilla.org/show_bug.cgi?id=1865080, this ballot ensures that all readers of the BRs understand that time periods measured in days (such as validation document reuse periods, random value usage periods, and revocation timelines) are measured precisely, not in calendar days.
Notes:
- This ballot bears some similarity to Ballot SC-52, which never came to a vote.
- This ballot does not strictly define a “month”, allowing infrequent tasks to continue to be executed on the same numeric day of each month, regardless of the number of days in that month.

The Extended Validation Certificates guidelines (EVGs) were developed and written in a specific format. Since then, the RFC 3647 has been the basis (and the de-facto standard) for the CA/Browser Forum to develop other documents.
This ballot aims to update the EVGs to follow the RFC 3647 format without changing any content, just moving current sections to those defined in the RFC 3647. There are no normative requirements changes.
This change also affects the Baseline Requirements for TSL certificates (BRs) which needs to point to the new sections of the EVGs. Both documents will be updated according to the latest version published.
