New on RIPE Labs: Internet Clouds are (also) Unpredictable
by Mirjam Kuehne 01 Mar '22

01 Mar '22

Dear colleagues, How does the largest cloud provider worldwide perform Traffic-Engineering? What are the implications for the geo-distributed applications running in the cloud? Marco Chiesa and his colleagues explored these and more questions through a comprehensive set of measurements across the Amazon Web Services (AWS) cloud network. Please find the results on RIPE Labs: https://labs.ripe.net/Members/marco_chiesa/internet-clouds-are-also-unpredi… Marco will be a RACI fellow at RIPE 79 and will present his research there. Kind regards, Mirjam Kühne RIPE NCC

Penetration Test Report for RPKI
by Bart Bakker 27 Dec '21

27 Dec '21

Dear colleagues, We are continuing our efforts to strengthen the security, compliance, and transparency of the RPKI system. Following on from last year's work, we asked an external party, Radically Open Security (ROS), to carry out a penetration test of our RPKI software from a user perspective earlier this year. ROS has shared a penetration test report on their findings. This testing complements the source code audit report published on 3 December. You can now find the Penetration Test Report by Radically Open Security and our response to their findings on our website [0]. We hope you will find these reports useful, and we look forward to your feedback.

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?

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.
