RPKI Service Criticality Questionnaire
by Job Snijders 10 Aug '22

10 Aug '22

Dear all, RIPE NCC has asked the Routing WG Chairs to facilitate a working group conversation on framing RIPE NCC's RPKI services subcomponents in terms of criticality. At the bottom of this email is a form that focusses on three components: confidentiality, integrity and availability. Each component is split into three questions (a, b, and c), a total of 9 questions are being put forward to the working group. We envision this process to be a public consultation: WG participants can submit (free-form) responses, and also chime in by replying to each other's responses; hopefully bringing us to a degree of consensus in the coming weeks. I believe this is an unique opportunity to help RIPE NCC! Investing our time - in turn - will help ourselves rely on and integrate RIPE NCC's RPKI services in our production environments. The goal is to help RIPE NCC develop a deeper understanding of how the moving parts fit together, which in turn helps decide where and how to invest resources. >>> Your feedback is much appreciated! <<< NOTE: if you are *NOT* a RIPE NCC member, and use the RIPE NCC Trust Anchor (e.g. as Relying Party to make informed routing decisions, inside and outside the RIPE region), your feedback *also* is much appreciated. Kind regards, Job, Ignas, Paul Routing WG co-chairs ----------------------- FORM STARTS BELOW ----------------------- Service Criticality Questionnaire Form - RPKI ============================================= Introduction ------------ This form is used to gather input from the community on the service criticality of the RPKI Service from RIPE NCC. The framework is detailed in: https://labs.ripe.net/author/razvano/service-criticality-framework/ The service criticality has three components: * Confidentiality: What is the highest possible impact of a data confidentiality-related incident (e.g. data leak)? * Integrity: What is the highest possible impact of a data integrity-related incident (e.g. hacking)? * Availability: What is the highest possible impact of a service availability-related incident (e.g. outage)? (All RIPE NCC services are designed with at least 99% availability, so please consider outages of up to 22 hours.) Service purpose --------------- The RIPE NCC RPKI Service is the RPKI Trust Anchor (TA) for the RIPE NCC service region, comprised of: * RPKI Dashboard (in the LIR portal) * Repositories (rsync/RRDP) * Certification Authorities (CAs) * RPKI Management API * Hardware Security Modules (HSMs) * Datasets Service Criticality ------------------- Please review the following three areas. ## (1) Global Routing Incident Serverity * Low (No / negligible impact) * Medium (One or a few ASes are unavailable) * High (Many ASes in a region are unavailable) * Very High (Global Internet routing disruptions) Please rate the incident serverity (Low to Very High) in the following three areas. Please explain why. (a) Confidentiality (Impact level of incidents such as data leaks) Answer 1a: (b) Integrity (Impact level of incidents such as hack attempts) Answer 1b: (c) Availability (Impact level of service outage incidents, up to 22 hours per quarter) Answer 1c: ## (2) IP addresses and AS Numbers Incident Serverity * Low (No / negligible impact) * Medium (Local disruptions (registration information not being available for some entities)) * High (Regional disruptions (registration information not being available for the RIPE NCC region)) * Very High (Global disruptions (lack of registration information for all AS Numbers and IP addresses)) Please rate the incident serverity (Low to Very High) in the following three areas. Please explain why. (a) Confidentiality (Impact level of incidents such as data leaks) Answer 2a: (b) Integrity (Impact level of incidents such as hack attempts) Answer 2b: (c) Availability (Impact level of service outage incidents, up to 22 hours per quarter) Answer 2c: ## (3) Global DNS Incident Severity * Low (No / negligible impact) * Medium (Local disruptions) * High (Regional disruptions) * Very High (Global disruptions) Please rate the incident serverity (Low to Very High) in the following three areas. Please explain why. (a) Confidentiality (Impact level of incidents such as data leaks) Answer 3a: (b) Integrity (Impact level of incidents such as hack attempts) Answer 3b: (c) Availability (Impact level of service outage incidents, up to 22 hours per quarter) Answer 3c: ---------------------------- FORM ENDS ------------------------------

Frequently Asked Questions about 2000::/12 and related routing errors
by Job Snijders 07 Jul '22

07 Jul '22

Dear all, Last night many people received "Resource Certification (RPKI)" alerts, which in turn caused my phone to light up with questions! :-) In the below message I'll attempt to provide an analysis of what happend and answer frequently asked questions. * What happened? * Has this happened before? * Why didn't RPKI Route Origin Validation (ROV) stop this? What happened? ============== As reported in the media (https://twitter.com/DougMadory/status/1544862409336184832) one Internet Service Provider announced to the world - through the BGP protocol - that all Internet Protocol addresses contained within 2000::/12 were reachable via them. This was a routing error, an error condition which triggered various monitoring systems around the globe. Background: The BGP Default-Free Zone is composed of ~ 150,000 IPv6 networks originated from ~ 24,000 Autonomous Systems (ASes). The totality of this is what forms the IPv6 Internet. The majority of these networks have a prefix length in the range of /32 up to /48. Currently the world's largest IPv6 assignments (of which there are very few) are clocking in at /19. So, a /12 ("slash twelve") BGP announcement covers an exceptionally large number of IP addresses! This night's /12 BGP announcement covered such a large block of address space, it happened to overlap with about 21,292 existing networks originated by 3,697 ASes. For roughly 69% (14,695) of those networks RPKI ROAs had been created. About 10% (2,176) of those "RPKI ROA covered existing networks" is IPv6 space managed under the RIPE NCC umbrella. I imagine a few hundred operators received alerts from RIPE NCC with a suggestion to considering creating corresponding ROAs to make the 2000::/12 announcement valid; however no ISP can create such a ROA, because no single ISP is authoritative for the entirety of that block. :) Has this happened before? ========================= Yes. This type of routing error happens almost annually. Some time ago Tom Strickx reported an incident involving 2400::/12, a block which nowadays overlaps with more than 40,000 networks! (source: https://twitter.com/Jerome_UZ/status/1145136294835523584) If my memory serves me right, back in 2016 AS 1299 originated both 2000::/6 and 2000::/12, later that year AS 10026 also originated 2000::/12 for a bit. So... how exactly can this happen? I believe it is a mixture of user-interfaces with really sharp edges and permissive EBGP filters. Many router-to-router linknets are assigned a /127 [RFC 6164] or a /64 [RFC 7421], and loopback addresses generally are assigned a /128 (a single address). It's not hard to imagine that when copy+pasting or typing by hand, an operator fails to input the last digit (respectively a 7 in the case of /127, the 4 in /64, or the 8 in /128), resulting in a configuration with a /12 or a /6 as the prefix length. See these Cisco & Juniper terminal transcript examples for a demonstration of failing to correctly enter the last digit of "2001:67c:208c::/128" : https://chloe.sobornost.net/~job/slash-twelve.txt Why didn't RPKI ROV stop this? ============================== Creating RPKI ROAs and performing Route Origin Validation (ROV) on received BGP route announcements helps protect against mishaps with unauthorized "same-length" and "more-specific" announcements. ROV (by design) does nothing against unauthorized "larger overlapping" route announcements (such as 2000::/12). This is because the Internet's global routing system is based on the Longest Prefix Match (LPM) algorithm (see https://en.wikipedia.org/wiki/Longest_prefix_match) LPM means that as long as your certified address space is in the global routing table, a less-specific announcement (such as 2000::/12) is not very likely to draw IP traffic away from your network. In incidents like these the major impact seems to be that monitoring systems are triggered (which is appropriate!). I suspect there is virtually no impact to business operations (fortunately!). Questions welcome! Kind regards, Job
