Video: What are “Negative Trust Anchors” for DNSSEC?

What are “negative trust anchors” for DNSSEC? What function do they perform? Why do we need them? In this video, Dan York interviews Jason Livingood about his Internet-Draft on this topic and answers these and other questions:

The Internet-Draft can be found at:

http://tools.ietf.org/html/draft-livingood-negative-trust-anchors

Jason and his co-author are seeking comment and would appreciate feedback from people about this draft – does it make sense? Would you use it? Do you see any ways to improve their ideas? Their email addresses can be found at the end of the document and they are definitely open to feedback.

Jason Livingood is Vice President of Internet & Communications Engineering at Comcast and is one of the co-authors of this draft.

Deploy360@IETF86: Day 5 – MIF, LISP, IPv6 Maintenance… and we’re done!

IETF LogoAnd so we reach Friday… the final day of the 86th meeting of the Internet Engineering Task Force (IETF)  where it’s a short day that ends early and for us within the Deploy360 Programme only hits two of our topics:  IPv6 and Routing Resiliency/Security.

General information about participating remotely can be found on the Remote Participation page as well as the IETF86 agenda – specific info for the groups we are following is included below.

Here’s the preview of how we’re finishing this very busy week…


0900-1100 Friday, March 15

Multiple Interfaces (MIF) – Caribbean 1
Computers and devices today have the ability to connect to multiple networks simultaneously. Think about a laptop that can connect over WiFi or Ethernet – or a smartphone that can connect over WiFi or the cellular data network.  In those cases which network interface should the device use?  The MIF working group is working to document the existing practices and outline the issues involved in a world where multiple network availability is routine.

Location/ID Separation Protocol (LISP) – Caribbean 6
The LISP working group is defining a series of experimental RFCs around a new routing protocol designed to improve the scalability of the Internet’s routing infrastructure.


1120-1220 and 1230-1330  Friday, March 15

IPv6 Maintenance (6man) – Caribbean 4

The 6man working group “is responsible for the maintenance, upkeep, and advancement of the IPv6 protocol specifications and addressing architecture.” (quoting the charter)  This is where most of the work is happening to refine the IPv6 protocol itself, and today’s session should be quite a busy one.


With those sessions, we’ll be closing out our work at IETF 86 this week.  Some of us will then be moving into a meeting of the Internet Society Advisory Council happening on Friday afternoon before we head to the Orlando airport for our flights home.

It’s been a great week and we’ve made some significant progress on a number of fronts!

On a final note, this is the first time we’ve posted these daily previews – were they helpful?  We’d love to hear your comments – either in response to this post, on social networks or via our email or feedback form. (Thanks!)

Deploy360@IETF86: Day 4 – IPv6, DNSSEC and Routing, Oh, My!

IETF LogoDay 4 of the 86th meeting of the Internet Engineering Task Force (IETF)  hits all of our Deploy360 topics – IPv6, DNSSEC and Routing Resiliency/Security.

General information about participating remotely can be found on the Remote Participation page as well as the IETF86 agenda – specific info for the groups we are following is included below.


0900-1130 Thursday, March 14

Homenet – Caribbean 3
This working group focuses on the evolving networking technology within and among relatively small “residential home” networks.

Interface to the Routing System (I2RS) – Caribbean 5
This is a new working group meeting for the first time that is seeking to define a publicly documented interface into the Internet’s routing system for applications to use. The best way to understand this new group would be to read draft-atlas-i2rs-problem-statement.


1300-1500 Thursday, March 14

Port Control Protocol (PCP) – Caribbean 6

The PCP working group is back again looking at how to enable communication from applications across middleboxes such as Network Address Translation (NAT) devices and firewalls for both IPv4 and IPv6.

Two other groups also may be of interest during this time block:


1510-1710 Thursday, March 14

Dynamic Host Configuration (dhc) – Caribbean 1
The DHC working group looks at DHCP and aspects of dynamically configuring IP addresses, both for IPv4 and IPv6, although the focus these days is on DHCPv6.

Operational Security  (opsec) – Caribbean 3
The OPSEC working group looks at the operational security concerns of IP networks. In this meeting there are 3 drafts focused on the security of IPv6 networks.


1730-1830 Thursday, March 14

Dynamic Host Configuration (dhc) – Caribbean 1
The DHC working group will continue to meet during this timeslot. Information is above.

DNS Operations  (DNSOP) – Caribbean 4
The DNSOP Working Group focuses on operational aspects of the Domain Name System and at this session has multiple drafts relating to DNSSEC.


1900-2100 Bits-N-Bites

This reception / networking time in Grand Sierra D should be an interesting chance to look at new technology from a number of sponsors.

2000-?  Alternative PKI Side Meeting, Boca 4

For those people interested in authentication and the public key infrastructure (PKI) aspects of the Web, there will be an “Alternative PKI Models Side Meeting” in room Boca 4, the IAB office, to talk about the requirements, goals and the design assumptions for a Web PKI.  Given our interest in DNSSEC and DANE, I (Dan) will be in this meeting to participate.

And after all of that… we’ll be trying to figure out how to get some food.  🙂

Deploy360@IETF86: Day 3 – Lots of IPv6 with a bit of Routing

For us within the Deploy360 Programme, Day 3 of the 86th meeting of the Internet Engineering Task Force (IETF)  is all about IPv6, IPv6 and more IPv6, with a tiny bit of routing thrown in for something different.  Two of the “big” working groups related to IPv6 meet today.  The Sunset4 working group is looking at what happens when you really start shutting down IPv4, and the V6ops working group is back again with more discussion of operational guidance around IPv6.

General information about participating remotely can be found on the Remote Participation page as well as the IETF86 agenda – specific info for the groups we are following is included below.


0900-1130 Wednesday, March 13

Softwire – Caribbean 2
The Softwire discussion continues from Monday with more looking at ways to connect IPv4 networks across IPv6 networks and connecting IPv6 networks across IPv4 networks… both important aspects of encouraging IPv6 deployment.

Inter-Domain Routing (IDR) – Caribbean 5
The IDR working group supports the use of Border Gateway Protocol (BGP) version 4 within IPv4 and IPv6 networks. The group works on maintenance of the BGP protocol as well as new extensions.


1300-1500 Wednesday, March 13

Sunsetting IPv4 (SUNSET4) – Caribbean 2

The Sunset4 working group is looking at issues around the transition from IPv4 to IPv6 and specifically at issues related to the shutting down of IPv4 and working in an IPv6-only environment. One important piece of work right now is related to developing a “gap analysis” between IPv4 and IPv6.


1510-1710 Wednesday, March 13

IPv6 Operations (V6ops) – Caribbean 5
Today v6ops will address several interesting drafts around design choices for IPv6 networks, security, operational guidelines for data centers and suggestions for the use of Unique Local Addresses.


1740-2010 Wednesday, March 13

IETF Operations and Administrative Plenary

While the operations and administrative plenary doesn’t usually directly relate to what we do here at Deploy360, it is a useful session to keep up with what changes are going on within the IETF as an organization and to learn about the current state of the organization.

And after that… we may try to have a team dinner, assuming we still have any energy left!  🙂

Deploy360@IETF86: Day 2 – Routing (SIDR, KARP, GROW) and NAT (PCP, BEHAVE)

IETF LogoFor the Deploy360 team, Day 2 of the 86th meeting of the Internet Engineering Task Force (IETF) yields an IETF86 agenda that primarily focuses for us on routing issue and network address translation. We’ll start the day off looking at routing in embedded networks then return into secure routing between networks.  We’ll then look at authentication in routing followed by protocols and methods of working with NAT and finishing out the day attending a session on global routing operations.

General information about participating remotely can be found on the Remote Participation page – specific info for the groups we are following is included below.


0900-1030 Tuesday, March 12

Routing Over Low power and Lossy networks (ROLL) – Caribbean 3
This working group is looking at what needs to be done for routing packets in embedded networks such as industrial networks, connected home networks and other sensor networks (sometimes called the “Internet of Things”).

I’ll note that the Aggregated Service Discovery BOF happening at the same time also looks like an interesting session and something we’ll probably want to monitor. The proposed AGGSRV charter explains the problem of service discovery that it is trying to solve.


1030-1130 Tuesday, March 12

Secure Interdomain Routing (SIDR) – Caribbean 1
This is the second session at IETF 86 of the primary working group dealing with routing security issues that we are now looking to cover in the future in our Routing Resiliency/Security section of Deploy360. There will be some good discussions here related to BGPSEC and RPKI that should be quite interesting.


1145-1245 Tuesday, March 12

While not directly related to what we do here at Deploy360, we’ll be at the “ISOC@IETF” panel on the topic of:

Internet Society Briefing Panel at IETF 86: “Content is King; How Do we Avoid Playing the Pauper?”

The Internet has stimulated innovation through disruption in any number of areas, not the least of which is redefining what it means to be a “publisher” — of written, audio, video or other content. As everyone — people, for- and not-for-profit businesses alike — becomes a publisher, what are the next steps needed in order to ensure that content is treated as its creator desires. That may mean restricted use, or facilitating widespread use. This is not new — when the first anonFTP indexer was created (Archie), it surprised some authors who thought they were sharing private draft copies of their manuscript on an FTP site. On the flip side, every now and then a photo or a video “goes viral” on the Internet generating interest and awareness beyond the creator’s capacity to track it.

Are there ways that Internet application layer infrastructure standards could be extended to capture the content creator’s intentions of use of digital content, to be as open or as restricted as that creator desires?

Given that we are a publisher of content, this general topic is certainly of great interest to us. Unfortunately, all the seats have been reserved in the session so there is no room left to attend, but you can both listen and watch the session here:


1300-1500 Tuesday, March 12

There are two groups of interest to us in this time period.

Keying and Authentication for Routing Protocols (KARP) – Boca 2

The KARP working group examines how to add communication security to routing protocols in the form of message authentication, packet integrity, and denial of service (DoS) protection.

Port Control Protocol (PCP) – Caribbean 1

The PCP working group looks at how to enable communication from applications across middleboxes such as Network Address Translation (NAT) devices and firewalls. The group is looking at solutions for both IPv4 and IPv6.


1520-1650 Tuesday, March 12

Behavior Engineering for Hindrance Avoidance (BEHAVE) – Caribbean 1

Continuing an afternoon of NAT, the BEHAVE working group looks at NAT issues as they relate to the interconnection of IPv6 and IPv4 networks.


1700-1830 Tuesday, March 12

Global Routing Operations (GROW) – Caribbean 1

The GROW working group looks at the operational aspects of the IPv4 and IPv6 global routing systems

And after all that, we’ll be a bit tired but will be heading out to the one night of IETF that is a social event. Given that it will be at the Harry Potter section of Universal Studios, one can only imagine the photos, eh? 🙂

Deploy360@IETF86: Day 1 – SIDR, Softwires and V6Ops

IETF LogoAs today’s 86th meeting of the Internet Engineering Task Force (IETF) begins, here are the sessions from the IETF86 agenda that we on the Deploy360 team will be attending (all times US Eastern).  General information about participating remotely can be found on the Remote Participation page – specific info for the groups we are following is included below.

0900-1130 Monday, March 11

There are two groups we want to follow so Jan will be probably be in one (Softwires) while I (Dan) am in the other (SIDR):

Softwires – Caribbean 2
This working group is looking at ways to connect IPv4 networks across IPv6 networks and connecting IPv6 networks across IPv4 networks… both important aspects of encouraging IPv6 deployment.

Secure Interdomain Routing (SIDR) – Caribbean 4
This is the primary working group at IETF dealing with routing security issues that we are now looking to cover in the future in our Routing Resiliency/Security section of Deploy360. There will be some good discussions here related to BGPSEC and RPKI that should be quite interesting.

1300-1500 Monday, March 11

This time block is easy as we all will be in the “v6ops” working group dealing with IPv6 operational issues. This is probably the most important working group for the IPv6 work we do here within Deploy360.

IPv6 Operations (V6ops) – Caribbean 3

1540-1710 Monday, March 11

This time block doesn’t have any sessions that are specific to the Deploy360 program, but several are of general interest:

  • History BOF – looking at ways to archive/record history of the Internet.
  • Netconf – a protocol to ease configuration of network devices
  • Oauth – an important protocol for web security
  • Transport Area – discussions of transport-related drafts and items that don’t fit in existing working groups

Links to the audio feeds and jabber rooms for those sessions can be easily found on the tools-style agenda page.

1740-1940 Monday, March 11 – Technical Plenary

The technical plenary doesn’t directly relate to the topics we cover here at Deploy360, but the lead session will be “The End of Plain Old Telephone Service (POTS)” by Henning Schulzrinne, the CTO of the US Federal Communications Committee (FCC) and should be quite interesting.

And that will be the end of a long day!

DNSSEC Discussion In DNSOP Working Group At IETF86 Next Week

IETF LogoAt the 86th meeting of the Internet Engineering Task Force (IETF) next week in Orlando there is one primary working group where DNSSEC will be discussed, the DNSOP (DNS Operations) working group.  As noted in our recently-published “Rough Guide To IETF 86’s Hot Topics“, DNSOP develops guidelines for the operation of DNS software servers and the administration of DNS zone files. It also documents DNSSEC operational procedures and looks at DNS-related IPv6 transition and coexistence issues.

The meeting is on Thursday, March 14, from 17:30 – 18:30 US Eastern time. The agenda and working group charter are:

Agenda: https://datatracker.ietf.org/meeting/86/agenda/dnsop/
Charter: https://datatracker.ietf.org/doc/charter-ietf-dnsop/

There are two major DNSSEC-related documents being discussed. First is draft-livingood-negative-trust-anchors, an interesting idea about how to use a “Negative Trust Anchor” to indicate within the DNSSEC-validating resolver that you want to accept DNS records for a given domain even if the DNSSEC-validation cames back as bad.  The primary use case for this is when there is a breakage of the DNSSEC chain of trust caused by, for instance, accidentally letting a key expire for a domain.  This idea came about from the team at Comcast when they dealt with issues like the nasa.gov key expiration.  It’s intended as a temporary measure that administrators can use while we are getting more DNSSEC deployed and the tools and processes are still evolving.

The second document is draft-kumari-ogud-dnsop-cds, a new draft that proposes a method of solving the dilemma of how to communicate a new Key Signing Key (KSK) to the parent domain using DNS itself.  This issue has been an ongoing challenge that has been in need of simplification – and this approach is one such proposal.  The mechanism, though, has proven to be quite contentious with a large volume of email to the dnsop mailing list.  It should generate quite an interesting discussion in the DNSOP meeting!

There may be a few other DNSSEC-related documents floating around in other working groups, but the DNSOP group on Thursday will be the major location of DNS-related discussion at this IETF 86 meeting.  Other DNS-related working groups such as DANE and DNSEXT chose not to meet as their work has been going on through the mailing lists and did not require a face-to-face meeting this time.

Note that if you can’t participate in person, there are several ways to participate remotely via audio, Jabber chat, WebEx and MeetEcho.

P.S. 3 of the 4 DO Team members will be at IETF 86 next week – please do say hello if you are there!

IPv6 Sessions at IETF 86 Next Week

IETF Logo

The 86th meeting of the Internet Engineering Task Force (IETF) is happening next week in Orlando and if you are interested in IPv6, there are quite a number of working groups where IPv6 will be discussed.  Our recently-published “Rough Guide To IETF 86’s Hot Topics” highlights three of the IPv6 groups:


v6ops (IPv6 Operations) WG

Joel Jaeggli is now an AD and John Brzozowski is taking over his job as WG chair along with Fred Baker. One draft to be discussed is draft-mlevy-v6ops-auto-v6-allocation-per-asn that led to some interesting discussions on the mailing list about the assertion that this draft enables networks to bypass the Regional Internet Registries (RIRs) in getting IPv6 space. It will be interesting to see whether this progresses or is discussed at the WG meeting during IETF 86.

There was a call for adoption of draft-binet-v6ops-cellular-host-requirements as a working group document. Most comments were in favor but there were a couple of articulate opponents. Many of the supporters are people working for adoption of v6 in mobile networks – mostly mobile operators.

Agenda: https://datatracker.ietf.org/meeting/86/agenda/v6ops/
Charter: https://datatracker.ietf.org/wg/v6ops/charter/
(11 March 2013, 1300-1530; 13 March 2013 1510-1710)

————–

6man (IPv6 Maintenance) WG

The 6man Working Group is charged with the maintenance, upkeep  and advancement of the IPv6 protocol specifications and addressing architecture, which is especially relevant as IPv6 begins to be deployed around the world at scale this year. A lot of the mailing list discussion since the last IETF meeting has been around the use of the U-bit and G-bit in the IPv6 iid as outlined in draft-carpenter-6man-ug. This draft hopes to clarify the use of these bits.

Agenda: https://datatracker.ietf.org/meeting/86/agenda/6man/
Charter: https://datatracker.ietf.org/doc/charter-ietf-6man/
(15 March 2013, 1120-1220, 1230-1330)

————–

sunset4 (Sunsetting IPv4) WG

sunset4 is a new working group in the Internet Area. The working group is an addresses the fact that the Internet is still largely IPv4, but in the presence of address exhaustion it cannot continue to be the Internet that we know today. The Internet will transition to IPv6 but there will be an interval where the Internet’s performance degrades as more coping mechanisms are adopted and before a complete transition to IPv6. This working group hopes to develop techniques to mitigate some of that pain. Sunset4 has a new charter proposed since the last IETF meeting, but it has not been approved. There has been little activity on the mailing list since IETF 85.

Agenda: https://datatracker.ietf.org/meeting/86/agenda/sunset4/
Charter: https://datatracker.ietf.org/doc/charter-ietf-sunset4/
(13 March 2013, 1300-1500)


Beyond those working groups, given that IPv6 is “the new normal” it can be found throughout many other groups, including:

IPv6-related drafts will also appear in a range of other working groups. Should be some excellent discussions and we’re looking forward to seeing progress made on a number of different drafts.

Note that if you can’t participate in person, there are several ways to participate remotely via audio, Jabber chat, WebEx and MeetEcho.
