RPKI ROA MaxLength - feature or misfeature? (UX/security)
by Job Snijders 11 Dec '21

11 Dec '21

Hi all, I'm writing the working group to initiate some conversation about a long-standing point of confusion in the RPKI ecosystem: the ROA MaxLength field. What is the ROA MaxLength field? ================================ The data format profile of RPKI ROAs allows an operator to specify the following fields: * 1 (one) Origin AS * one or more IPv4 or IPv6 prefixes * for each IP prefix, a so-called 'MaxLength' value Operators are allowed to create multiple ROAs with different Origin ASNs covering the same prefix, folks can mix-and-match as needed. The "MaxLength" feature essentially is a macro function (a 'shortcut'): when you create a ROA with the following parameters: Prefix: 2001:67c:208c::/48 MaxLength: 50 Origin AS: 15562 The above Prefix + Maxlength has the exact same meaning as: Prefix: 2001:67c:208c::/48 or 2001:67c:208c::/49 or 2001:067c:208c:8000::/49 or 2001:67c:208c::/50 or 2001:67c:208c:4000::/50 or 2001:67c:208c:8000::/50 or 2001:67c:208c:c000::/50 Origin AS: 15562 The confusion & an UX experiment proposal ========================================= I suspect that many people think that "xxx/48 maxlength 50" means "the /48, AND the four individual /50s" (mentally skipping over the intermediate /49s). Going back as far as 2011 [1] - the concept of "MaxLength" appeared less than straight-forward, the quest for a good 'default setting' seems a challenge. My experience at NTT taught me that encouraging customers to create IRR "route:" or "route6:" objects that *exactly* match what people intend to announce in the BGP plane, greatly simpifies things. Just register what you want to announce, nothing more, nothing less. A proposal for UX experiment: would it be beneficial to HIDE the 'maxlength' field (for some period of time) in the RPKI ROA management system hosted by RIPE NCC? If the option isn't there, it can't confuse people. Wouldn't it be better to encourage people to create ROAs that align one-to-one with BGP announcements? (keep in mind: IRR route/route6 objects don't have the notion of maxlength). Or an enhancement: a button "also create ROAs for all /24s and /48s, but not the intermediate prefix lengths". This saves people a lot of clicking if they want to prepare for maximum de-aggregation. Is MaxLength used in the wild? ============================== Only 15% of Validated ROA Payloads (VRPs) under the RIPE NCC Trust Anchor have the MaxLength field set to something other than the aggregate Prefix Length. I'm not entirely convinced that accommodating the 15% is worth the hassle of explaining what the heck MaxLength is. Removing MaxLength from the UI does not in any way impact anyone's ability to create as many ROAs as they deem fit, it just forces people to be precise! :-) Thoughts? Kind regards, Job [1]: https://labs.ripe.net/author/alexband/using-the-maximum-length-option-in-ro…

Code Audit Report for RPKI
by Bart Bakker 10 Dec '21

10 Dec '21

Dear colleagues, Continuing from the work we started last year on strengthening our security compliance, we have asked an external party to carry out a security audit of our RPKI code. This was an important element in preparation for open sourcing the RPKI core code, which will be done in early January 2022. We are publishing the security report for the second year in an effort to increase transparency and trust in the RPKI system. On our website [0], you will now find the code audit report written by Radically Open Security 2021 and our response to their findings. We hope you will find these reports useful, and we look forward to your feedback.

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-…
