At O’Reilly’s 2007 Emerging Telephony conference last week in San Francisco, I had the opportunity to give a 15-minute presentation to all attendees about VoIP security. Rather than doing the traditional slideware outlining the threats, tools, best practices, etc., I tried to do something very different and simply tell a story of what could happen if a VoIP system were installed in an insecure manner – and how to go about securing that system. I tried to make it interesting and humorous (something not often tied to VoIP security) and the feedback at the show was quite positive. The audio and slides are now available over at Blue Box and I’d definitely be interested in any feedback you all have about the presentation, either in content or style.
