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 ------------------------------

RPKI Quarterly Planning Q3 2022
by Nathalie Trenaman 29 Jun '22

29 Jun '22

Dear colleagues, The quarterly planning for Q3 2022 for RPKI has now been published: https://www.ripe.net/manage-ips-and-asns/resource-management/rpki/rpki-plan… <https://www.ripe.net/manage-ips-and-asns/resource-management/rpki/rpki-plan…> Recently, we published a page for the different components of RPKI which can be accessed at: https://status.ripe.net <https://status.ripe.net/> We’re still carrying on with the activities started in Q1 2022 such as implementing "Publish in Parent" RFC 8181 support and creating multiple parallel internal test environments for RPKI. We’ll announce here on the list when these have finished. Also, we’re currently starting the process for the purchase of the new HSMs, which we will start to use as soon as we can. The goal of our quarterly planning is to communicate the work we’re doing for the coming months, get your input and start a discussion on other developments we should work on. If you have any comments or questions, we hope you'll discuss with us on the list or, if you prefer, you can always contact the team directly at rpki(a)ripe.net <mailto:rpki@ripe.net> . Kind regards, Nathalie Trenaman Routing Security Programme Manager RIPE NCC

RPKI Outage on 23 June 2022 from 10:50 UTC - 12:00 UTC
by Stella Vouteva 28 Jun '22

28 Jun '22

Dear colleagues, Yesterday, we performed an upgrade on the Security world software on our RPKI core servers. The upgrade was finished at approximately 08:45 UTC. We tested the upgrade and verified that everything worked before enabling the RPKI dashboard again. At approximately 10:50 UTC, we received an alert from our monitoring that showed an error for both our online Hardware Security Modules (HSMs). While we immediately started the investigation of this alert, we also decided to temporarily stop RPKI Core to keep a consistent state. This also meant that we had to temporarily close down the RPKI Dashboard. At 11:22 UTC we contacted our vendor as we had never seen this behaviour before. A consultant from our vendor advised a reboot of the HSMs, which we performed at 11:55 UTC. After the reboot, the HSMs got back online and we enabled the RPKI Core and RPKI dashboard. It is still unknown whether the upgrade was the direct cause of the errors, as the error was very generic. While we are working on finding the root cause, we still need to reboot systems and HSMs occasionally, which causes unavailability of the RPKI Dashboard for a few minutes and it will take a bit longer than usual for objects to get published in our repository. As soon as we have more information, we will share it here. As a result of this outage, we will speed up the process to replace the online HSMs, which we described in our recent RIPE Labs article <https://labs.ripe.net/author/ties/securing-the-ripe-ncc-trust-anchor/> [0]. Kind regards, Stella Vouteva [0]: https://labs.ripe.net/author/ties/securing-the-ripe-ncc-trust-anchor/
