Network Monitoring SIG News

Around 60 attendees joined the 5th NM-SIG meeting 'Monitoring and Detection of Fast-Flux Service Networks'. The NM-SIG had invited 3 speakers to talk about this topic, namely David Watson(The Honeynet Project), Jose Nazario(Arbor Networks) and Christian Gorecki(University of Mannheim). David gave an introduction on Fast-Flux Service Networks. Jose talked about Fast-Flux detection via Arbor's project ATLAS. And Christian presented an approach to automate detection of Fast-Flux with certain metrics. The last part of the meeting was called 'Bring your demo'. Three people gave a short demo of network monitoring tools. Florian Weimer explained the approach of passive DNS replication, which also can be used to track Fast-Flux domains. Tillmann Werner gave a demo of 'Nebula', an intrusion signature generator. And Piotr Kijewski showed HoneySpider Network, a client honeypot solution. The feedback of this meeting was very positive and we hope to plan more of these meetings in the near future.
