RPKI Publication Server v2.0
by Bart Bakker 31 Jan '23

31 Jan '23

Dear colleagues, Today we released a new major version (v2.0.0) of our RPKI Publication Server, in which the embedded database has been replaced using a PostgreSQL database. Additionally, we have also fixed a moderate security issue regarding bad mTLS configuration. You can get more information in the security advisory [1]. We advise you to upgrade your RPKI Publication Server, particularly if you run it in production. You can download the source code for this release from the project release page [2] and access the prebuilt docker image on docker hub [3]. If you need any help upgrading the RPKI Publication Server, we’ll be happy to help. [1] - https://github.com/RIPE-NCC/rpki-publication-server/security/advisories/GHS… [2] - https://github.com/RIPE-NCC/rpki-publication-server/releases/tag/v2.0.0 [3] - https://hub.docker.com/layers/ripencc/rpki-publication-server/v2.0.0/images… -- Kind regards, Bart Bakker Senior Software Engineer RIPE NCC

Re: [routing-wg] RPKI ROAs and Monitoring

Thanks for the inputs. I now went with packetvis. Does anybody know who is behind packetvis? The home page is pretty quiet. Basically it works, but I would have expected that packetivs also shows ROAs. It show all my prefixes, but it does not show which of them have ROAs and which not. I guess I will give BGPalerter also a try. regards Klaus > -----Ursprüngliche Nachricht----- > Von: Massimo Candela <massimo(a)us.ntt.net> > Gesendet: Montag, 12.

Guide to using RIPE NCC's RPKI Publication Service
by Alex Band 03 Jan '23

03 Jan '23

The RIPE NCC RPKI Publication Service for delegated Certification Authorities (CAs) is currently in an open beta phase: https://www.ripe.net/manage-ips-and-asns/resource-management/rpki/paas-onbo… Running Delegated RPKI has several advantages. Most notably, you can seamlessly manage multiple organisational entities in a single instance, even spanning several RIR service regions, and you can delegate resources to other business units or customers who in turn run their own CA to manage ROAs. In just a few weeks, RIPE NCC’s RPKI Publication Service is already hosting over 2000 Validated ROA Payloads, already cementing it as a popular member service. To help others get started, I published a step-by-step guide to do this with free, open-source RPKI CA software Krill by NLnet Labs: https://blog.nlnetlabs.nl/running-krill-under-ripe-ncc/ All the best for 2023, Alex P.S. ARIN and APNIC offer RPKI publication services as well, and there are similar guides for these RIRs: https://blog.nlnetlabs.nl/running-krill-under-arin/ https://blog.nlnetlabs.nl/running-krill-under-apnic/

RPKI's 2022 Year in Review: growth & innovation
by Job Snijders 31 Dec '22

31 Dec '22

Dear all, With 2023 at our doorstep, I'd like to share some perspective on how RPKI evolved in the year 2022. Impact on the Global Internet Routing System ============================================ Decision makers might wonder: is investing time and resources worth it? What is the effectiveness of RPKI Route Origin Validation (RPKI-ROV)? In the last year a number of interesting reports were published. Even though less than half of BGP routes is covered by RPKI ROAs [6], based on flow data, Kentik estimates [2] nowadays the majority of IP traffic is destined towards RPKI-valid BGP routes. Their follow-up report [3] (analysing BGP control-plane data) suggests that evaluation of a BGP route as RPKI-invalid reduces its propagation by anywhere between one half to two thirds. Cloudflare [4] published a report analysing data-plane connectivity between a select number of ASes and RPKI-invalid destinations: they estimate 6.5% (lower-bound) of residential Internet users enjoy the benefits their ISP doing RPKI-ROV. Another experiment report [5] (focussed on data-plane connectivity between validators and RPKI-valid/RPKI-invalid destinations), concluded the existence of RPKI ROAs helped move 75% of test traffic towards the correct destination. The above metrics might appear all over the place (6.5% up to 75%), but keep in mind these analyses are not mutually exclusive. Observations of the Internet's topology are a function of the observer's vantage point. All the referenced reports agree on key points: * ROAs have a measurable & significant impact on global IP traffic delivery * RPKI-ROV helps reduce the "blast radius" of BGP routing incidents * They recommend to continue the global deployment of RPKI-ROV (rejecting RPKI-invalid BGP routes), and create ROAs for all IP address space. Year to Year Growth of the distributed RPKI database ==================================================== In comparison to "effectiveness", the bare existence, size, contents, and number of Signed Objects in the globally distributed RPKI repository system is much easier to quantify. The below table was constructed by comparing two December 31st RPKIviews.org snapshots [1] of validated RPKI caches, primed with the ARIN, AFRINIC, APNIC, LACNIC, and RIPE Trust Anchors. 2021-12-31 2022-12-31 Total cache size (KiB): 996,216 1,240,572 (+24%) Total number of files (objects): 192,503 242,969 (+26%) Publication servers (FQDNs): 36 52 (+44%) Certification authorities: 28,328 34,901 (+23%) Route origin authorizations: 101,645 138,323 (+36%) Unique VRPs: 302,025 390,752 (+29%) IPv4 addresses covered: 1,139,561,719 1,354,270,410 (+19%) IPv6 addresses covered: 7,499,405,083 9,446,853,925 (+26%) *10^24 Unique origin ASNs in ROAs: 27,174 34,455 (+27%) A healthy growth rate across the board! With the ubiquitous availability of "Publication as a Service" hosted by RIRs, I expect (and hope!) the growth of the number of distinct publication servers to stall, or even drop in 2023. The number of Certification Authorities (CAs) closely corresponds to the number of RIR members (RIR customers) who opted to enable RPKI services for their Internet Number Resources, making it a useful proxy metric to understand how many organisations are creating RPKI ROAs. A single Route origin authorizations (ROA) can contain one or more Validated ROA Payloads (VRPs), and one or multiple ROAs can contain the exact same VRP information. "Unique" in the above table indicates the metric's underlaying data was deduplicated. Each ROA can only contain a single Origin ASN. Multiple ROAs can refer to the same Origin ASN value. Innovation through Standardisation ================================== The IETF SIDROPS [7] working group (the designated forum in which volunteers collaborate to define and specify open standards for RPKI and RPKI-based technologies) was fairly productive in 2022 and managed to publish 5 RFCs: RFC 9286 - Manifests for the RPKI (revision) RFC 9255 - The 'I' in RPKI Does Not Stand for Identity (clarification) RFC 9319 - The Use of maxLength in the RPKI (clarification) RFC 9323 - A Profile for RPKI Signed Checklists (RSCs) (innovation) RFC 9324 - Policy Based on the RPKI without Route Refresh (innovation) The above body of work consists mostly of revisions of older work or clarifications on how to use the RPKI, to me this demonstrates a somewhat conservative approach (rather than innovation at breakneck speed), which I consider a good thing. Outlook & Conclusion ==================== Now that globally Route Origin Validation has advanced as far as it has, the next obvious target is BGP path validation, to mitigate two distinct problems: BGP route leaks and BGP AS_PATH spoofing. Both painful to network operators! While projects like OpenBSD's validator rpki-client and NLNetLabs' signer Krill made significant headway to support both BGPsec and ASPA, the industry as a whole still (especially the BGP implementations) have a decent chunk of work ahead. Once the freshly-created software runs on BGP routers and RIR portals offer BGPsec+ASPA functionality, operators need to investigate initial deployment strategies. RPKI clearly is the technology of choice to improve safety and security of the global Internet routing system. Adoption of RPKI continues to grow. I'm excited to learn how far we'll be at the end of 2023!

The presence of default routes does not in any way diminish the value of RPKI-ROV, but does distort some types of measurement.
