1. Roll Call

The Roll Call was taken.

2. Read Antitrust Statement

The Antitrust Statement was read.

3. Review Agenda

No changes to the agenda were noted. It was noted that Wayne Thayer volunteered to take minutes for this meeting. Dimitris will take the minutes for the next call.

4. Approval of minutes from last teleconference

Accepted without objections.

5. Validation Subcommittee Update

Wayne said that the subcommittee continued discussions of the end-entity certificate profile on the past call. EKU was discussed, as was the remainder of the profile. Then discussion shifted to remaining work and Subject distinguishedNames. Issues with validating the stateOrProvinceName were discussed, as were concerns over the organizationalUnitName field.

Tim said that he will not be able to attend next week’s call.

6. NetSec Subcommittee Update

Neil said that two ballots are in process. We have feedback from Ryan and Wayne on SC34 (Account Management) on GitHub and are planning to address it. SC28 has just begun voting. We have created a discussion document for using cloud services for hosting CA services. This will not result in any immediate ballots, but will feed into future changes. Meeting today to model threats. This relates to the dropped zones ballot, shifting from physical to logical zones.

Ben said that we’re still trying to finalize the offline CAs ballot. Have replaced ‘offline’ with ‘air gapped’. Bruce commented that we should populate the Trusted Roles section in the BRs with some of the info in the NCSSRs. We’re still trying to determine how to best structure the document. If parts of the NCSSRs are incorporated into the BRs it makes it more difficult for other WGs such as code signing to rely on them. This will also be discussed on the call today.

Dimitris said that the original consensus was for individual WGs to decide to adopt parts of the NCSSRs as they wish, then if we determine that there is seen to be a need for a shared common set of NCSSRs in the future we can discuss it.

Ben: There is a threat modeling group meeting today at 1 PM EST. If anyone with expertise has time to participate, please let us know and they will be invited.
