<p class="MsoNormal"><span style="color:black">Dear EPDP Team, </span></p>
<p class="MsoNormal"> </p>
<p class="MsoNormal"><span style="color:black">During our calls in the past two weeks, the team has reviewed the String Similarity Small Group’s work outcome and subsequently, EPDP team members were asked to consult with their appointing organization on the
proposed hybrid model for the string similarity review. The team is expected to have a follow-up discussion and share more feedback / input during this week’s meeting, on Friday, 26 August at 13:30-15:00 UTC. </span></p>
<p class="MsoNormal"> </p>
<p class="MsoNormal"><span style="color:black">To this end, the leadership team and staff would like to quickly recap the discussion and remind the team of the scope and remit of the small group’s work. </span></p>
<p class="MsoNormal"> </p>
<p class="MsoNormal"><span style="color:black">Comparing primary labels and requested allocatable variants in the String Similarity Review is generally supported by the EPDP Team. However, some EPDP Team members have expressed reservations about including non-requested
allocatable variants and blocked variants in a String Similarity Review.</span></p>
<p class="MsoNormal"> </p>
<p class="MsoNormal"><span style="color:black">The small group’s recommendation for including all variants is due to its key consideration of the failure models, which are “denial of service” and “misconnection”. The small group believes that misconnection,
in particular, is more problematic. Arriving at the wrong site, for example, can result in credential compromise and accidental exposure of information. If the confusing similarity is maliciously leveraged, it can be a DNS abuse vector. </span></p>
<p class="MsoNormal"> </p>
<p class="MsoNormal"><span style="color:black">The small group also believes that failure modes require mitigation as much as possible, and that the string similarity review provides an opportunity to do so.
<u>To meet the singular goal of risk mitigation</u>, the small group agreed that the hybrid model was the most appropriate. </span></p>
<p class="MsoNormal"> </p>
<p class="MsoNormal"><span style="color:black">Nevertheless, the small group did not consider the implementation complexity of the hybrid model and deferred this to the EPDP Team to deliberate. As a next step, the EPDP team is to determine if the hybrid model
is the appropriate path forward, taking into account factors such as:</span></p>
<ul style="margin-top:0in" type="disc"><li class="MsoNormal" style="color:black;vertical-align:baseline">
Likelihood and impact of the failure modes, especially the misconnection risk</li><li class="MsoNormal" style="color:black;vertical-align:baseline">
Operational impact of the hybrid model</li><li class="MsoNormal" style="color:black;vertical-align:baseline">
Cost and benefit of hybrid model</li></ul>
<p class="MsoNormal"> </p>
<p class="MsoNormal"><span style="color:black">We hope this framing would be useful for your consideration of the small group’s recommendation. We look forward to further discussion during this week’s call. </span></p>
<p class="MsoNormal"> </p>
