<p class="MsoNormal"><span lang="EN-US" style="color:black">There has been discussion for some time in the SCWG of a “browser alignment ballot” that would import certain rules from browser root programs to the Forum’s Baseline Requirements. Entrust Datacard
is generally in favor of such a ballot, but with certain limitations.</span><span lang="EN-US"><o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="color:black">The CA/Browser Forum was created in 2005 so that CAs and browsers could work together and agree on industry “best practices” by consensus. We measure “best practices” consensus by our voting rules
– no modification can be made to the Baseline Requirements unless it is approved by a majority of browser members and also by 2/3 of CA members. <span class="apple-converted-space"> </span></span><span lang="EN-US"><o:p></o:p></span></p>

<span lang="EN-US" style="color:black">Over the years, some browsers have modified</span><span lang="EN-US"> their root program<span style="color:black"> rules
</span>in ways that affects <span style="color:black">the ecosystem. We believe </span>
root program changes should work their way through the forum first <span style="color:black">
so there is no need for later alignment of </span>these<span style="color:black"> rule</span> changes<span style="color:black"> with the BRs.</span><o:p></o:p></span></p>

<span lang="EN-US" style="color:black">1. We should not include any browser root program rule in the ballot if it conflicts with policy of another browser root program.<span class="apple-converted-space"> </span></span><span lang="EN-US"><o:p></o:p></span></p>

<span lang="EN-US" style="color:black">2. In addition, an alignment ballot should not introduce controversial issues that have already been rejected in the Forum, but should only include non-controversial changes. For this reason, we believe Ballot SC31 should
not include Apple’s recent root program rule change reducing maximum certificate lifetimes from the present 825 days (as currently allowed by the BRs) to 398 days. As you all remember, this same change to the BRs was proposed in late 2019 in Ballot SC22 and
was highly controversial. The ballot was unanimously approved by those browsers who voted, but failed by a large margin among CAs.</span><span lang="EN-US"><o:p></o:p></span></p>

<span lang="EN-US" style="color:black">In addition, at the time of Ballot SC22 it did not appear that the browsers gave any consideration to the concerns of an equally important part of the internet security ecosystem which would also be necessary to establish
industry consensus on best practices – the website owners themselves, who are also important customers of the browsers. Poll results from 3,850 website owners (including many enterprise website owners) conducted by three CAs showed that 82% of website owners
oppose the reduction in the maximum certificate validity period to 398 days. Many website owners asked at the time what security problems existed with two-year certificates that were solved by moving to one-year certificates and
</span><span lang="EN-US">also asked <span style="color:black">for a cost-benefit analysis from the browsers, but no clear answer was ever provided to them. <span class="apple-converted-space"> </span></span><o:p></o:p></span></p>

<span lang="EN-US" style="color:black"> </span><span lang="EN-US"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="color:black">In our opinion, browsers should not ignore the results of an unsuccessful ballot in the Forum, add the rejected provision to their root programs anyway, and then ask the Forum members to reverse their
prior votes and add the rejected provision to the Forum’s best practices documents. This would be setting a very bad precedent for collective decision-making for the future.</span><span lang="EN-US"><o:p></o:p></span></p>

<span lang="EN-US" style="color:black">For this reason, Ballot SC31’s proposed change to a 398-day maximum validity period does not represent consensus among CAs, website owners, and browsers. This part of Ballot SC31 is not the type of browser root program
rule change that should be included in a browser root program alignment ballot. <span class="apple-converted-space"> </span></span><span lang="EN-US"><o:p></o:p></span></p>
