    <abstract>
      <t>The IETF Nominating Committee (NomCom) appoints candidates to several IETF
leadership committees. RFC8713 provides criteria for membership on NomCom that
attempt to ensure that NomCom volunteers are members of the loosely defined
IETF community, by requiring in-person attendance in three of the past five in-
person meetings. In 2020 and 2021, the IETF had six consecutive fully online
plenary meetings that drove rapid advancement in remote meeting technologies and
procedures, including an experiment that included remote attendance for NomCom
eligibility. This document updates RFC8713 by building a new set of eligibility
criteria from first principles, with consideration for the increased salience of
remote attendance.</t>

      <name>Introduction</name>
      <t><xref target="RFC8713"/> defines the process for selection of the Internet Architecture
Board (IAB), Internet Engineering Steering Group (IESG), IETF Trust, and one
IETF LLC Director. A key actor in the process is the Nominating Committee
(NomCom), which nominates a single candidate for each open position, subject to
confirmation by other bodies.</t>
      <t>NomCom voting members are volunteers that have met certain eligibility
requirements. The actual NomCom is selected at random from the pool of eligible
volunteers. Thus, it is important that members of the pool be IETF participants
likely to have knowledge of IETF processes and practices. There are restrictions
to ensure that no more than two volunteers with the same primary affiliation are
chosen.</t>
      <t><xref section="4.14" sectionFormat="of" target="RFC8713"/> requires that volunteers must have attended three of
the previous five meetings. In practice, this has meant that the volunteer
picked up their registration badge. Current members of the Internet Society
Board of Trustees and bodies for which the NomCom nominates members are
ineligible.</t>
      <t><xref target="RFC8989"/> specified an experiment in the wake of six consecutive fully online
meetings from 2020 to 2021, where the traditional interpretation of the
requirement would have resulted in no eligible volunteers. It extended the
attendance requirement to define meeting attendance as including logging in to
at least one session of a fully-online IETF meeting.</t>
      <t>RFC8989 also created two other tracks to obtain eligibility: (1) serving as a
working group chair or secretary in the past 3 years, and (2) author or editor
of an IETF Stream RFC in the past five years, including internet-drafts in the
RFC Editor queue.</t>
      <t>This document discusses some of the first principles that inform the design of
NomCom eligibility, and makes recommendations on how the process of
qualification based on attendance should work.</t>
      <t>This document replaces the attendance criteria in <xref section="4.14" sectionFormat="of" target="RFC8713"/>
with criteria based on those in <xref target="RFC8989"/>, and obsoletes RFC8989 to make it
clear that that document has been superceded. The other paragraphs of
<xref section="4.14" sectionFormat="of" target="RFC8713"/> remain intact.</t>

    <section anchor="nomcom-principles">
      <name>NomCom Principles</name>
      <t>The NomCom is intended to be composed of randomly selected members of "the
community." For many years, in-person attendance was a reasonable proxy for the
commitment associated with being a member. Two days of travel and an attendance
fee is a relatively large expenditure of time and money. Additionally, in-person
attendance is thought to increase personal familiarity with candidates for
leadership positions and with the spirit of the IETF, although there is no
mechanism to ensure any interactions. Finally, the NomCom interview process was
largely conducted in-person at IETF meetings, so the ability to attend was a
prerequisite to participate.</t>
      <t>A basic principle is that the community should govern itself, so volunteers
must have a demonstrated commitment to the IETF. Limiting the number of
volunteers sponsored by any one organization avoids the potential for mischief
that disrupts IETF operations or works against the interests of the community as
a whole.</t>
      <t>However, attitudes to business travel evolve, and remote meeting technology
continues to improve, to the extent that many longstanding community members
choose to participate remotely. The system has always excluded some from
attendance, and thus qualification from the NomCom, due to cost or personal
reasons. Further, the NomCom has completed two cycles using entirely online
tools.</t>
      <t>Counting remote attendance lowers the barriers to entry. As IETF is committed to
having a no-fee remote option (<xref target="I-D.ietf-shmoo-remote-fee"/>) the only
required investment is to log on once per meeting at a specific time (sometimes
a locally inconvenient hour). While this document does not formally impose a
requirement for the NomCom to function entirely remotely, including remote-only
attendees in the pool is likely to effectively require a remote component to
NomCom operations.</t>
      <t>Finally, overly restrictive criteria work against getting a deep talent pool.</t>
    </section>
    <section anchor="criteria">
      <name>Criteria</name>
      <t>The following paths to qualification replace <xref section="4.14" sectionFormat="of" target="RFC8713"/>. Any
one of the paths is sufficient, unless the person is otherwise disqualified
under <xref section="4.15" sectionFormat="of" target="RFC8713"/>.</t>
      <t>Path 1:
The person has registered for and attended 3 out of the last 5 IETF meetings,
either in-person or online. In-person attendance is as determined by the record
keeping of the Secretariat. Online attendance is based on being a registered
person who logged in for at least one session of an IETF meeting.</t>
      <t>Path 2:
The person has been a Working Group Chair or Secretary within the 3 years prior
to the day the call for NomCom volunteers is sent to the community.</t>
      <t>Path 3:
The person has been a listed author or editor (on the front page) of at least
two IETF Stream RFCs within the last 5 years prior to the day the call for
NomCom volunteers is sent to the community. An Internet-Draft that has been
approved by the IESG and is in the RFC Editor queue counts the same as a
published RFC, with the relevant date being the date the draft was added to the
RFC Editor queue. For avoidance of doubt, the 5-year timer extends back to the
date 5 years before the date when the call for NomCom volunteers is sent to the
community.</t>

    <section anchor="security-considerations">
      <name>Security Considerations</name>
      <section anchor="nomcom-capture">
        <name>NomCom capture</name>
        <t>The most potent threat associated with NomCom eligibility is that an
organization or group of coordinating organizations would attempt to obtain a majority of
NomCom positions, in order to select an IETF leadership in support of an agenda
that might be self-serving and against the interests of the community as a
whole.</t>
        <t>Note that <xref target="RFC8713"/> lets the Chair decide the NomCom voting requirement, so a
simple majority may be inadequate. However, 7 of 10 forms a quorum, so at worst
seven NomCom members working together can almost certainly impose their will.</t>
        <t>Whatever the merits of admitting remote attendees, it reduces the minimum cost
of creating a NomCom-eligible volunteer from three in-person trips of ~5 days each
over the course of at least 8 months, to zero financial cost and the time
required to log in three times over at least 8 months. Some organizations might
not be deterred in either case, while others might now find such an attack to not be
feasible.</t>
        <section anchor="a-surge-of-volunteers">
          <name>A Surge of Volunteers</name>
          <t>A large number of "legitimate" volunteers makes it quite difficult to control 6
of 10 NomCom slots. Setting aside limitations on the number of selections from
any organization, basic probability shows that to have even a 50% chance of
controlling 6 or more NomCom positions, an attacker needs roughly 60% of the
volunteer pool. For example, if there are 300 "legitimate" volunteers, an
attacker must produce 365 volunteers to exceed a 50% chance of NomCom capture
(see <xref target="capture-math"/>).</t>
          <t>A sudden surge in the number of volunteers, particularly of people that no one
recognizes as a part of the community, is an early-warning sign for the
community, leadership and the IETF Secretariat to further investigate. The IETF
should monitor and assess a sudden increase in the number of online registration
fee waivers awarded in accordance with
<xref section="4" sectionFormat="of" target="I-D.ietf-shmoo-remote-fee"/>.</t>
          <t>While loosening eligibility criteria lowers the cost to an attacker of producing
eligible volunteers, it also increases the number of "legitimate" volunteers
that increases the difficulty of an attack.</t>
        </section>
        <section anchor="the-two-per-organization-limit">
          <name>The Two-Per-Organization Limit</name>
          <t>The two-per-organization limit in <xref target="RFC8713"/> complicates such an attack.  To
circumvent it, an organization must either (1) coordinate with at least two
like-minded organizations to produce a NomCom majority, (2) incentivize members
of other organizations (possibly through a funding agreement) to support its
agenda, or (3) propose candidates with false affiliations.</t>
          <t>While the IETF does not routinely confirm the affiliation of volunteers, as part
of an investigation it could eliminate volunteers who have misrepresented said
affiliation. Publishing the list of volunteers and affiliations also gives the
community an opportunity to review the truth of such claims.</t>
          <t>Assuming that 300 legitimate volunteers are all from different organizations,
three conspiring organizations would need 771 volunteers (257 per organization)
for a 50% chance of NomCom capture (see <xref target="capture-math"/>).</t>
        </section>
        <section anchor="one-year-of-participation">
          <name>One Year of Participation</name>
          <t>Attendance at 3 meetings requires at least 8 months. Given the volume of
volunteers necessary to capture the process, an attack requires a surge in
attendees over the course of a year. Such a surge might trigger a community
challenge to the list of eligible volunteers, and/or a leadership investigation
to detect suspicious behavior (e.g. logging in to a single session and then
immediately logging out). In the event of abuse of process, the leadership would
then have months to adjust policy in response before the NomCom cycle begins.</t>
        </section>
      </section>
      <section anchor="disruptive-candidates">
        <name>Disruptive candidates</name>
        <t>Note that the normalization of consistent remote participation allows for a
single individual to mount an attack that previously required coordination. By
registering for IETF meetings using a number of different identities over a year, an individual
can make each of those identities NomCom eligible and then serve under any one
of them that is selected for the NomCom.  Once selected, an individual could
seek to disrupt the process or prevent the timely conclusion of its work.</t>
        <t>This attack is much harder to detect or prevent than equivalent attacks were
previously, as it does not require coordination among multiple attendees.
While the attacker cannot be sure of fee waivers for some or all of the
different identities, the lower cost for remote participation also makes this
attack more feasible than it would have been under prior rules.</t>
        <t>However, the voting member recall procedure in <xref section="5.7" sectionFormat="of" target="RFC8713"/> exists
to allow removal and replacement of disruptive figures.</t>
      </section>
      <section anchor="additional-remedies">
        <name>Additional remedies</name>
        <t>Additional changes to the process to further obstruct attacks against the
NomCom are beyond the scope of this document. However, a challenge process
against volunteers with a suspicious reported affiliation, or that might be
aliases of a single volunteer, could trigger an investigation.</t>
        <t>Similarly, the challenge to the random selection described in
<xref section="4.17" sectionFormat="of" target="RFC8713"/> can explicitly include appeals against the data
used to qualify the volunteer, rather than the randomization process.</t>
