  1. Roll Call

Clint Wilson read the roll.

3. Discussion Items a. We currently don’t have any ballots in discussion.

b. David Kluge gave an update regarding ongoing risk assessment work. He mentioned that we have finalized the assets section and are at a place where we can start assessing but are struggling with the methodology for documenting the assessment. In the last cloud sub-group call it was proposed that we use Microsoft’s STRIDE model. Trev offered to bring in a threat modeling expert. Trev is still following-up with them.

c. David, Trev and Clint also discussed about the OCSP SLA changes (OCSP SLA Document). There were some discussions around preference between global SLOs in the BRs or SLO/SLA publications in the CPSs. There were no strong preferences or reservations expressed by anyone. David will draft something and this will be taken back to other WGs. Bruce Morton expressed that this will involve changes in not only TLS BRs but other WG BRs as well.

d. No updates on zones ballot

e. Ben spent some time talking through all the issues that he has created in Github: NetSec Issues on Github. Ben collected all the WebTrust Task Force’s comments and put all the pending issues in Github.

S/MIME Requirements
v1.0.14 - Ballot SMC016 - May 5, 2026

This ballot maintains consistency between the S/MIME Baseline Requirements and the TLS Baseline Requirements with changes introduced by Ballots SC096 and SC097. Specifically, this ballot: Creates a carve-out of the logging requirements for DNSSEC specifically, stating these are not in scope. For audit purposes, change management logging is able to confirm if the appropriate controls are in effect or not. Sunsets all remaining use of SHA-1 signatures in Certificates and CRLs. It is noted that most uses of SHA-1 signatures are already deprecated by SC097. With this ballot, all unexpired Subordinate CA Certificates issuing S/MIME containing the SHA-1 signature algorithm must be revoked. This proposal does not prohibit the use of SHA-1 to generate issuerKeyHash or issuerNameHash values as currently required by RFC 5019. Includes minor formatting corrections.

Network and Certificate System Security Requirements
Version 2.0.5 (Ballot NS-008) - Jul 9, 2025
