Re: SRI's Dan Lynch dies

[Stan Barber]

Charles calls out the major reason the InterOp conferences were so useful
to so many. It is a shame there is nothing like this today in many domains
like IPv6 or Smart Home or others.

Thanks to Dan for his work to drive this kind of effort during the early
days of the commercial Internet.

Re: SRI's Dan Lynch dies

[Charles Spurgeon]

Well said. Dan Lynch's requirement that vendor gear must interop on
the show floor was a big deal and required extra work to accomplish
compared to other "dog and pony" shows.

His ground rules for the Interop conferences had the effect of
ensuring that competent people showed up to set up and run the gear
being shown. Interoperability also ensured that vendors got the
opportunity to find bugs and fix things (whether they wanted to or
not) which helped improve the quality of vendor offerings.

Another benefit was that the people who showed up to make things work
on the show floor were often available during the show as resources to
answer questions or help with issues.

As a result of Dan's efforts the Interop conferences were a very
valuable resource both for attendees and vendors for a number of
years.

Call for Participation -- ICANN81 DNSSEC and Security Workshop for ICANN Policy Forum

[Jacques Latour via NANOG]

Call for Participation -- ICANN DNSSEC and Security Workshop for ICANN Policy 
Forum



In cooperation with the ICANN Security and Stability Advisory Committee (SSAC), 
we are planning a DNSSEC and Security Workshop for the ICANN80 Policy Forum 
being held as a hybrid meeting from 10-13 June 2024 Kigali, Rwanda in the 
Central Africa Time - CAT (UTC +2). This workshop date will be determined once 
ICANN creates a block schedule for us to follow; then we will be able to 
request a day and time. The DNSSEC and Security Workshop has been a part of 
ICANN meetings for several years and has provided a forum for both experienced 
and new people to meet, present and discuss current and future DNSSEC 
deployments.  For reference, the most recent session was held at the ICANN79 
The Community Forum on Wednesday, 06 March 2024. The presentations and 
transcripts are available at: https://icann79.sched.com/.


The DNSSEC Workshop Program Committee is developing a program for the

upcoming meeting.  Proposals will be considered for the following topic areas 
and included if space permits.  In addition, we welcome suggestions for 
additional topics either for inclusion in the ICANN78 workshop, or for 
consideration for future workshops.



1.  Global DNSSEC Activities Panel

For this panel, we are seeking participation from those who have been involved 
in DNSSEC deployment as well as from those who have not deployed DNSSEC but who 
have a keen interest in the challenges and benefits of deployment, including 
Root Key Signing Key (KSK) Rollover activities and plans.



2.  DNSSEC Best Practice

Now that DNSSEC has become an operational norm for many registries, registrars, 
and ISPs, what have we learned about how we manage DNSSEC?



  *   Do you still submit/accept DS records with Digest Type 1?
  *   What is the best practice around key roll-overs?
  *   What about Algorithm roll-overs?
  *   Do you use and support DNSKEY Algorithms 13-16?
  *   How often do you review your disaster recovery procedures?
  *   Is there operational familiarity within your customer support teams?
  *   What operational statistics have been gathered about DNSSEC?
  *   Are there experiences being documented in the form of best practices, or 
something similar, for transfer of signed zones?



Activities and issues related to DNSSEC in the DNS Root Zone are also desired.



3. DNSSEC Deployment Challenges

The program committee is seeking input from those that are interested in 
implementation of DNSSEC but have general or concerns with DNSSEC.  We are 
seeking input from individuals that would be willing to participate in a panel 
that would discuss questions of the following nature:


  *   Are there any policies directly or indirectly impeding your DNSSEC 
deployment? (RRR model, CDS/CDNSKEY automation)
  *   What are your most significant concerns with DNSSEC, e.g., complexity, 
training, implementation, operation, or something else?
  *   What do you expect DNSSEC to do for you and what doesn't it do?
  *   What do you see as the most important trade-offs with respect to doing or 
not doing DNSSEC?



4. Security Panel

The program committee is looking for presentations on DNS, DNSSEC, routing and 
other topics that could impact the security and/or stability of the Internet.



We are looking for presentations that cover implementation issues, challenges, 
opportunities, and best practices for:


  *   Emerging threats that could impact the security and/or stability of the 
Internet
  *   DoH and DoT
  *   RPKI (Resource Public Key Infrastructure)
  *   BGP routing & secure implementations
  *   MANRS ( Mutually Agreed Norms for Routing Security)
  *   Browser security – DNS, DNSSEC, DoH
  *   EMAIL & DNS related security – DMARC, DKIM, TLSA, etc…



If you are interested in participating, please send a brief (1-3 sentence) 
description of your proposed presentation to 
dnssec-security-works...@icann.org 
by COB Friday, 10 May 2024.



Thank you,

Jacques
