<p class="MsoNormal"><span style="color:rgb(31,73,125);font-family:Calibri,sans-serif;font-size:11pt">However, as I understand it Google wants to prevent a genuine Google employee from buying a cert from a CA that is not on a corporate-approved list of CAs shown
in a CAA record, and so Google is supporting CAA as a way of preventing genuine Google employees from ordering a cert from a CA not on Google’s CAA list. I can see why an enterprise like Google might want that, but to my mind a cert issued with the approval
of a genuine Google employee from a CA not on the corporate CAA list of approved CAs is

in enforcing internal corporate policies.</span></p></span></div></div></blockquote><div><br></div><div>While I appreciate your attempt to educate me on terminology, please re-read that I communicated: unauthorized issuance.</div><div><br></div><div>We discussed this at the F2F as well - the challenges provided in the current BRs for the language provided, which allows restricting authorized cert requestors, but only to CAs for which the company has a pre-existing relationship. The specific nature of this conversation was with your employers' other representative, Bruce Morton, and in the context of discussing how, in the absence of a strict enforcement of CAA, it would be necessary to address this loophole (which some members present expressed as 'unintentional') via policy.</div><div><br></div><div>If it appears that I'm frustrated with you, it is the case, because you in particular have asked this question. If you recall, you asked the same question Jeremy did, during the F2F not even a week ago, and I responded to you, in person, immediately following your asking it.</div><div><br></div><div>So please don't position it that I haven't answered this before - on the list, on calls, and less than a week ago in person.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div lang="EN-US" link="blue" vlink="purple"><div class="m_6118434826916238797WordSection1"><span class="">
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1f497d">So –
<b><i><u>excluding</u></i></b> cases where a genuine Google employee has ordered or obtained a cert for a Google domain from a CA not on Google’s CAA list of approved CAs (not considered “misissuance” for the purpose of this question) – can you provide any
details as to other cases where CAA would have prevented true “misissuance” of a cert to a fraudster not connected to the organization that owns the domain in question? Those examples would be very helpful to this discussion.</span></p></span></div></div></blockquote><div><br></div><div>The examples I provided you, in person, at Meeting 39, were specifically about third-parties, not Google employees. The same examples I've provided you every time you've asked, but for which I'll link to this thread from now on. </div></div></div></div>
