New on RIPE Labs: Improving the Resiliency of RPKI Relying Party Software
by Alun Davies 11 Nov '21

11 Nov '21

Dear colleagues, Koen van Hove talks us though a series of fifteen distinct tests carried out to examine the security of RPKI infrastructure. Learn more about the motivation and method behind it all, as well as the outcome, in this new article on RIPE Labs: https://labs.ripe.net/author/koen-van-hove/improving-the-resiliency-of-rpki… Kind regards, Alun Davies RIPE Labs Editor RIPE NCC

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-…

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

Relative size of IRR registries

Recent discussions about ARIN-NONAUTH made me wonder what would be the impact of discontinuing *-NONAUTH IRR registries. These are the current size of all IRR registries I was able to mirror, ordered by the number of aut-num objects. source | total obj | rt obj | aut-num obj RIPE 948401 368596 37284 APNIC 879374 572495 17737 RADB 1533619 1344618 8787 TC 21423 8531 3412 ARIN 134512 50543 2211 RIPE-NONAUTH 58436 54807 2163 AFRINIC 121639 94734 2057 IDNIC 8541 4574 1713 ALTDB 25598 18319 1395 LACNIC 8008 4742 1039 ARIN-NONAUTH 67715 62471 939 WCGDB 65135 62849 773 NTTCOM 453257 444518 548 JPIRR 13404 11398 425 LEVEL3 111770 91524 299 CANARIE 1869 1455 177 BELL 29827 29613 105 BBOI 1291 924 56 RGNET 74 40 6 NESTEGG 8 4 2 REACH 20310 18207 2 HOST 2 0 1 OPENFACE 25 17 1 PANIX 42 40 1
