[ Apologies if you saw this elsewhere already - jtk ] Friends, colleagues, fellow operators, The network security track, formerly known as the ISP security BoF, has plans to return at NANOG 75 in San Francisco February 18-20. I will be your track facilitator. I have a small handful of topics I'm soliciting from some folks directly, but options are good, and I may be missing something important. If you haven't heard from me already, then I want to hear your ideas or proposals. This is a good, casual place to go with netsec related ideas, tools, or case studies. Here is an incomplete list of relevant topics to stir your thoughts: * IRRs, BGPSEC, and RPKI * DDoS attacks and mitigation * Botnet case studies * ISP incident response tools * Network censorship and privacy * Threat sharing frameworks * Network equipment configuration/default BCPs * Spoofing, amplification, reflection threats * ...insert your idea here John
