Changes to RRDP repository postponed - new RPKI rp/validator software releases tomorrow 15:00 CET
by Ties de Kock 08 Nov '21

08 Nov '21

Dear colleagues, As a result of a coordinated vulnerability disclosure process, many relying party (RP)/"RPKI validator" implementations will release a new version tomorrow at 15:00 CET. The vulnerabilities can hang or crash an RP instance. The vulnerabilities are not likely to have a direct impact: An attacker needs to participate in the RPKI ecosystem actively and have control over a publication point. Unfortunately, authoritative public information is only available in Dutch [0]. We consider it unlikely that the new relying party versions will interact with our new RPKI publication server. However, because we could not test using these upcoming releases, out of an abundance of caution, we have decided to postpone our release of the new publication server until the sixteenth of November. Furthermore, we will not do any other deployments tomorrow. We encourage you to apply these security updates as soon as possible when they become available. As a reminder, support for the RIPE NCC RPKI Validator 3 ended on the first of July; security updates for RPKI Validator 3 will not be available; please use a supported RP implementation. Kind regards, Ties de Kock [0] https://www.ncsc.nl/actueel/nieuws/2021/oktober/29/aanstaande-bekendmaking-…

Add BGPsec support to Hosted RPKI?

Changes to the RRDP repository
by Ties de Kock 28 Oct '21

28 Oct '21

Dear colleagues, Over the past months, we have been working on the RIPE NCC RPKI repositories. We have an update to the RRDP repository that we plan to deploy on 9 November. This will create a regular RRDP event (a session change) but will have no other externally visible impact. We want to share some of the improvements this change has to offer and highlight two areas in particular. First, we have improved the publication server software [0]. The current publication server uses an embedded NoSQL/schemaless database. We have changed the project to use PostgreSQL instead, which allows us to move several integrity checks to the publication server’s database. Second, we have changed how the publication server is deployed, which is part of our work to move components of our infrastructure on-premise. Initially, we will run two independent instances, with separate database servers and data centres, with each instance receiving all objects in the repository. We aim to keep this simple at an initial stage, closely monitor how the environment behaves, and expand later if we need to. Because the RRDP session differs between the instances, one instance is (and can be) active at each moment in time. This allows us to swap them out during an upgrade and allows us to fall back to the second one if any issue is being detected. Both instances are behind a load-balancer, which is the origin for the Content Delivery Network (CDN) that we use. By using a CDN, we (a) reduce the latency from various geographical locations, (b) protect ourselves from network glitches, and (c) reduce the bandwidth peak after a session change that would interfere with other services on the RIPE NCC network (for example during a deployment). This change is an intermediate step in our work on the resiliency of our publication infrastructure. We have extensively looked at possible architectures that can solve the issues we are facing now and considered numerous failure modes, and we think this design strikes a good balance between resilience and simplicity. We will discuss our architectural changes with the community at RIPE 83 and look forward to hearing your feedback. If you have any questions, please get in touch with us. Kind regards, Ties de Kock [0]: https://github.com/RIPE-NCC/rpki-publication-server

Too large AS-sets
by Antti Ristimäki 19 Oct '21

19 Oct '21

Colleagues, I'd like to hear how you others deal with those peers, whose AS-sets expands to way too large prefix-lists and/or as-paths. There are some networks that only ever add members to their AS-sets, but never remove. I have some deep frustration at (automatically) configuring our routers with prefix-lists or as-path filters that are magnitude or two as big as the specific peer's real advertised route count. Modern router platforms can quite easily handle large configs, but gigantic as-path filters seem to cause unnecessary increase in commit times at least in our JunOS platforms. The penalty feels higher than the reward. After all, if the peer's AS-set expands to cover big portion of the entire ASN space, I'm begin to ponder whether it would make more sense to drop IRR based as-path filtering altogether for those peers and use e.g. some sort of generalized peerlock filter? Are there any others as frustrated as I am and how have you solved this issue? I will appreciate constructive feedback. -Antti

Your opinion on Internet monitoring and measurements - a 10min survey
by Pavlos Sermpezis 18 Oct '21

18 Oct '21

Hi all, Do you use Internet monitoring and measurements (e.g., RIPEstat, RIPE RIS/Atlas, RouteViews, bgp.he.net, etc.) for your operations? What are your use cases? We (researchers) are trying to identify limitations and biases of the Internet monitoring infrastructure, and come up with ideas to fix them. We would like to hear your opinion! Please help us by answering our short anonymous survey; it should take less than 10min. Survey URL: https://forms.gle/9xJpYFw3PBo8KShz9 Thank you in advance, Pavlos Sermpezis PS. You can find more about our research project (funded by RIPE NCC) here https://sermpezis.github.io/ai4netmon/ -- Pavlos Sermpezis Postdoctoral researcher Datalab (https://datalab.csd.auth.gr/) Informatics Dept.

Add BGPsec support to Hosted RPKI?
by Job Snijders 18 Oct '21

18 Oct '21

Dear all, [ TL;DR: What does the working group think about supporting an extension to the RPKI Dashboard to enable publication of BGPsec certs? ] At the moment the hosted "RPKI Dashboard" at https://my.ripe.net/#/rpki, only permits Resource Holders to create RPKI objects of one specific type: ROAs. However, a wider range of RPKI cryptographic product types also exists, for example: BGPsec Router Certificates [RFC 8209]. BGPsec is a RPKI-based technology which enables network operators to transitively validate whether a given BGP UPDATE - indeed - passed through the Autonomous Systems listed in the path. One way to think of BGPsec is as an ECDSA protected network of channels between a receiving EBGP node; and one (or many) routers in the BGP route's Origin AS. I think BGPsec can be useful to protect "private peering" at large scale, and another use case is to increase confidence in routing information distributed via IXP Route/Blackhole Servers. Right now, routing protocol researchers and network operators wishing to publish BGPsec Router Keys, also have to learn how to master "Delegated RPKI": a deployment model with a steep learning curve. I think there are benefits to the community if RIPE NCC appends an activity to the "RPKI Planning and Roadmap" to implement procedures to sign and publish BGPsec Router Keys via a PKCS#10 / PKCS#7 exchange, callable via both API and dashboard WebUI. What do others think? Kind regards, Job Relevant documentation: https://datatracker.ietf.org/doc/html/rfc8209 https://datatracker.ietf.org/doc/html/rfc8635

Support for "Publish in Parent" [RPKI RFC 8181]?
by Job Snijders 08 Oct '21

08 Oct '21

Hi working group, In recent mail threads the concepts of "Hosted RPKI" and "Delegated RPKI" came up, but as mentioned by Tim and Rubens, another flavor also exists! A "hybrid" between Delegated and Hosted, informally known as "publish in parent" (aka RFC 8181 compliant Publication Services). There are multiple benefits to the general RPKI ecosystem when RIRs and NIRs support RFC 8181: * Resource Holders are relieved from the responsibility to operate always online RSYNC and RRDP servers. * Reducing the number of Publication servers reduces overall resource consumption for Relying Parties. Consolidation of Publication Servers improves efficiency and is generally considered advantageous. * Helps avoid "reinventing the wheel": it might be better to have a small group of experts build a globally performant and resillient infrastructure that serves everyone, rather than everyone building the 'same' infrastructure. Other RIRs and NIRs are also working on RFC 8181 support. RFC 8181 is relatively new so it'll take some time before we see universal availability. NIC.BR (available): https://registro.br/tecnologia/numeracao/rpki/ APNIC (available): https://blog.apnic.net/2020/11/20/apnic-now-supports-rfc-aligned-publish-in… ARIN (planned): https://www.arin.net/participate/community/acsp/suggestions/2020/2020-1/ Is implementing RFC 8181 support something RIPE NCC should add to the https://www.ripe.net/manage-ips-and-asns/resource-management/rpki/rpki-plan… ? What do others think? Kind regards, Job Relevant documentation: https://datatracker.ietf.org/doc/html/rfc8181

RPKI planning @ RIPE (Was: Support for "Publish in Parent" [RPKI RFC 8181]?)

Ah, thank you for the clarification. Are there any other items that predate the existence of the "Community Input on Planning" table on [1]? As some RPKI projects are multi-quarter or even multi-year projects, it might be good to expand the community's visibility into the list of RPKI-related work items which RIPE NCC to some degree has accepted, but not yet scheduled.

request for feedback: a RPKI Certificate Transparency project?
by Job Snijders 20 Sep '21

20 Sep '21

Dear all, With summer turning to fall in the Northern Hemisphere, yet again a new schoolyear is ahead of us! :-) I hope you all are well. I'm writing the group to solicit feedback for me and others to consider during upcoming deliberations about activity plans, but even more so as an RPKI enthusiast who is curious to learn what others see as potential future evolutions of the RPKI technology stack. [ TL;DR - Ask to the routing community: is there interest to coordinate and support an industry-wide project to introduce the principles of "Certificate Transparency" to the RPKI? The project size could be substantial, but so are the upsides. ] Intro: global deployment & operation of the RPKI is a multi-decade project ========================================================================== Over the last 21 years this industry has collectively helped grow and nurture 'Secure BGP' [1] into the RPKI/BGP deployment as we know it today: the smallest and largest of networks in the Default-Free Zone core are anchoring their BGP routing decisions to a RPKI covering 31% of space, which in turn helps connect billions of End Users to the Internet. >From my personal perspective [10], the RPKI has now reached some level of maturity. Perhaps now is the time for some of our community's focus to shift towards designing and implementing innovations on top of the current RPKI, without jeopardizing its current plateau of stability. What does trusting a Trust Anchor mean? ======================================= Some people have (correctly!) pointed out that RPKI Trust Anchor (TA) operators technically can issue certificates related to any Internet Number Resource, a consequence of some people considering "all resources" [5] being subordinate a necessity for day-to-day TA operations. While I am aware of some minor concerns about the "all resources" framework (and I personally see room for improvement!), for me the big question is not "who do I trust?", but "what did they actually do after I started trusting them?". In this reality where RIRs can sign "everything" and I (as RP operator) can cryptographically verify that what I observed through periodic polling [6] was indeed signed by my locally configured Trust Anchor(s)... one thing seems to be missing! I don't know anything about what my RP didn't observe! :-) Perhaps some certificates were issued and very quickly revoked concerning subordinate Internet Number Resources of great importance to me? How would I know if I didn't see it myself? I don't expect to trust Trust Anchor operators to never make any mistakes, but I do wish to be in a position where I can assess past performance, and can compare third-party audit logs, to inform my future decisions! To me it seems important to increase our collective visibility into TA/CA takes & mistakes. ("Mistakes" meaning the issuance or revocation of certificates non-compliant with the policy outlined in RIPE-751). Most Internet Routing incidents are analyzed after-the-fact through the use of Route Views [8], RIPE RIS [9], or information viewplayers like BGPlay. Everyone being enabled to "scrub back in time" greatly enhances our group's ability to understand what transpired and how to prevent it going forward. What is the RPKI equivalent of BGPlay at a cryptographicly auditable level of detail? ... maybe Certificate Transparency? [7]. Copying good ideas from other PKIs: Certificate Transparency ============================================================ The RPKI is built on top of X.509 and CMS tech. Any developments in other X.509 special interest communities (such as WebPKI [2], aka "the https:// experts"), may be amazing ideas or methods worth copying into 'our Internet Number Resource PKI' ecosystem. One of the inventors [3] of public-key cryptography (a core concept in the RPKI), also came up with an idea known as "Merkle Trees" [4]. This concept can be used to construct inter-domain "append-only" logging facilities, which can be incredibly useful to help increase trust in a Trust Anchor in an "assumed trust" model. I'll try to explain why below! A key concept in Certificate Transparency is that a CA ('the signer') - ahead of time - shares with select third parties (so-called 'CT Logs') their commitment to sign a given digital object. After acknowledgement from the CT Log(s), the signer proceeds to sign and publish the RPKI object. The CT Logs use Merkle Trees to allow external auditors to 'losslessly replay' all observations of certificate issuance from a given CT Log, and compare CT Logs with each other. Implementation of Certificate Transparency would provide this community with something analogous to the RIPE Database "Historical Queries". The major difference being all logged data comes with cryptographic assurances, and the data can be hosted and audited by both RIPE NCC and any third parties (anyone with Internet access!). RIPE NCC sending precertificate information to CT Logs? ======================================================= Would the community mind if RIPE NCC proactively shares to-be-signed not-yet-public-but-soon-to-be-public information with third parties? Are there any third parties (could be ISPs like you and me, or RIRs [13] in other regions) who'd be willing to host and operate 24/7 available CT Logs working with software such as Trillian [12]? RIPE NCC as Certificate Transparency Log Operator for other RIRs? ================================================================= RIPE NCC appears to have an impressive track record when it comes to bootstrapping and maintaining 'impossible' multi-year projects which improve "the commons". RIPE Atlas and RIPE RIS are projects only very few organizations would've been able to pull off. Both RIS and Atlas offer incredible value to both the RIPE community and the global community. In my eyes an RPKI Certificate Transparency initiative would align well with existing projects. Bootstrapping and maintaining RPKI CT Logs (the open source software design, subsequent IETF draft contributions, ongoing data processing and archiving) will require significant investment. However, I do believe there is an opportunity for RIPE NCC to serve the global Internet community by offering RPKI CT Log services to any TA or CA in the RPKI. Final thoughts ============== Certificate Transparency is an open framework that can help detect Signed Object trust threats, and brings increased oversight and openness to the RPKI ecosystem. Does the community see value in applying Certificate Transparency to the RPKI? What are your thoughts?

A Changing User Interface for rpki-validator.ripe.net
by Nathalie Trenaman 10 Sep '21

10 Sep '21

Dear colleagues, As we have already announced, we have ended support for our RPKI Validator. We have still been running our Validator 3 on http://rpki-validator.ripe.net <http://rpki-validator.ripe.net/> as an informational service to the community. However, we will be replacing our validator with Routinator on Thursday 16 September. Routinator has a new User Interface, so this migration will change the look and feel of http://rpki-validator.ripe.net <http://rpki-validator.ripe.net/>. In order to prepare for this change, you can try out the new UI that Routinator will use at https://routinator.nlnetlabs.nl <https://routinator.nlnetlabs.nl/> More details are in our RIPE Labs article at https://labs.ripe.net/author/nathalie-trenaman/a-changing-user-interface-fo… <https://labs.ripe.net/author/nathalie-trenaman/a-changing-user-interface-fo…> Best regards, Nathalie Trenaman Routing Security Programme Manager RIPE NCC

AS5400 -- British Telecom contact?
by Ronald F. Guilmette 04 Sep '21

04 Sep '21

Do any of you folks happen to have a networking contact within British Telecom that you could share with me? I tried emailing then at network(a)bt.com but got no response. I suspect that their routing of 169.129.0.0/16 is, um, inappropriate.
