Real-time BGP hijacking detection: ARTEMIS-1.0.0 just released
by Vasileios Kotronis 21 Dec '18

21 Dec '18

Dear operators, FORTH's INSPIRE group and CAIDA are delighted to announce the public release of the ARTEMIS BGP prefix hijacking detection tool, available as open-source software at https://github.com/FORTH-ICS-INSPIRE/artemis ARTEMIS is designed to be operated by an AS in order to monitor BGP for potential hijacking attempts against its own prefixes. The system detects such attacks within seconds, enabling immediate mitigation. The current release has been tested at a major greek ISP, a dual-homed edge academic network, and a major US R&E backbone network. We would be happy if you'd give it a try and provide feedback. Feel free to make pull requests on GitHub and help us make this a true community project. ARTEMIS is funded by the RIPE NCC Community Projects 2017, European Research Council (ERC) grant agreement no. 338402 (NetVolution Project), the Comcast Innovation Fund, US NSF grants OAC-1848641 and CNS-1423659 and US DHS S&T contract HHSP233201600012C.

Fwd: BGP Experiment
by Job Snijders 20 Dec '18

20 Dec '18

For your information! ---------- Forwarded message --------- From: Italo Cunha <cunha(a)dcc.ufmg.br> Date: Thu, Dec 20, 2018 at 6:39 PM Subject: BGP Experiment To: NANOG <nanog(a)nanog.org>, DISCO experiment mailing list <disco-experiment(a)googlegroups.com> NANOG, We would like to inform you of an experiment to evaluate alternatives for speeding up adoption of BGP route origin validation (research paper with details [A]). Our plan is to announce prefix 184.164.224.0/24 with a valid standards-compliant unassigned BGP attribute from routers operated by the PEERING testbed [B, C]. The attribute will have flags 0xe0 (optional transitive [rfc4271, S4.3]), type 0xff (reserved for development), and size 0x20 (256bits). Our collaborators recently ran an equivalent experiment with no complaints or known issues [A], and so we do not anticipate any arising. Back in 2010, an experiment using unassigned attributes by RIPE and Duke University caused disruption in Internet routing due to a bug in Cisco routers [D, CVE-2010-3035]. Since then, this and other similar bugs have been patched [e.g., CVE-2013-6051], and new BGP attributes have been assigned (BGPsec-path) and adopted (large communities). We have successfully tested propagation of the announcements on Cisco IOS-based routers running versions 12.2(33)SRA and 15.3(1)S, Quagga 0.99.23.1 and 1.1.1, as well as BIRD 1.4.5 and 1.6.3. We plan to announce 184.164.224.0/24 from 8 PEERING locations for a predefined period of 15 minutes starting 14:30 GMT, from Monday to Thursday, between the 7th and 22nd of January, 2019 (full schedule and locations [E]). We will stop the experiment immediately in case any issues arise. Although we do not expect the experiment to cause disruption, we welcome feedback on its safety and especially on how to make it safer. We can be reached at disco-experiment(a)googlegroups.com.

Join the RPKI Deployathon, 7-8. March 2019, , Amsterdam
by Vesna Manojlovic 20 Dec '18

20 Dec '18

Dear colleagues, The RIPE NCC and Juniper Networks are co-hosting the first RPKI deployathon - a two-day event which will bring together network professionals to work on practical aspects of routing security. We are looking for participants who want to learn about RPKI (Resource Private Key Infrastructure) , and receive some hands-on assistance while deploying it. Specifically, we are looking for: * network operators with access to routers * network engineers from all possible backgrounds (Enterprise, ISP, CDN, Content Providers, etc.) * & administration staff that have access to the RIPE NCC’s LIR portal You do not need to have prior knowledge or experience on routing security to attend the deployathon. Please apply if you would like to learn, specially if your learning style is "learning-by-doing" and team-work. -------------------- How to Apply -------------------- Interested? Apply online today: https://www.ripe.net/participate/forms/apply/rpki-deployathon-amsterdam/ *The application deadline is 29th January* Find out more on RIPE Labs: https://labs.ripe.net/Members/becha/join-the-amsterdam-rpki-deployathon-2019 Warm regards, Vesna Manojlovic Community Builder RIPE NCC Summary: * Date and Time: 7 - 8 March 2019, 9:00 - 17:00 CET * Location: Juniper Networks (Amsterdam Office), Boeing Avenue 240, Schiphol-Rijk * Deadline for applications: 29 January 2019
