I gave the closing presentation recently at the Judgement Day 8 cybersecurity conference in Bratislava, Slovakia. It was an interesting forum, with presentations earlier in the day by folks from F-Secure, Checkpoint, IBM, McAfee, HP and Cisco. Of these, the presentation by Michal Remper (Cisco) was particularly interesting, a discussion of the “Hastily Defined Networks” that Cisco has provided in a number of crisis situations, including in the aftermath of Hurricane Katrina. At the end of his presentation, Michal summarized a few lessons from the Cisco experiences in cases such as this. Although he didn’t put it quite this way, one of the key lessons was that however hastily the emergency network has to be provided, it is vitally important to have it well thought through and well-defined before the emergency occurs. In fact, the lesson I came away with was that what’s needed is Not-so-hastily defined networks. But is that really possible? Are there disasters that we simply can’t plan for and that will always require the flexibility to create hastily-defined responses?
