Friends, colleagues, fellow operators, The network security track, formerly known as the ISP security BoF, returns at NANOG 57. One option we're considering is taking a few moments for veterans and newcomers to get up and doing a 2 minute or less security contact personal introduction, akin to the peering personals that have been in done in the peering sessions for years. If you're planning on attending and are willing to stand up and introduce yourself to the group, please contact me offline. In addition, we may have room for one or two more brief discussion topics or lightning talks. If anyone, especially newcomers, have something they'd really like to present, conduct a demonstration of or coordinate a brief discussion about, I'd be grateful for your follow ups. Here is an incomplete list of ideas to help stir your thoughts: * Botnet take downs * BGPSEC and RPKI update or trial deplolyments * DDoS case study * Control plane best practices and templates * DNS RPZ overview and/or experience * Embedded device problems and protections * Government regulatory and compliance issues * Malware analysis * Mobile issues * MPLS and VLAN security issues * Route leak/hijack monitoring and mitigation * VM and cloud security challenges * <insert your new cool tool or idea here> Note, this track is not streamed nor recorded.
