I was one of the attendees at the fourth ISOI workshop last week, which this time was held in sunny San Jose. Once again, the event had an interesting range of presentations and discussions, mostly focused around what system defenders could do now to make a difference to the continuing tide of cybercrime observed every day. There was also plenty of opportunity to catch up with people in the security community, and put faces to names, so thanks to Gadi and co for the continued invites. I also got a bit of time to hang out with various Honeynet Project people and some of the guys from Shadowserver, and hopefully we’ll see some interesting spin offs in the coming months. Being from the UK, the obligatory Silicon Valley geek tourism was also fun too.
