The Do Over: Building A Green-field F500 Infrastructure

Presented at Security B-Sides London 2012 by

Nick Selby

"When a targeted nation-state sponsored attack was launched against a F500 which had for years under-invested in its IT and its security, the company had only one choice: build a totally new, secure, global IT infrastructure from the switches and routers up. And it had to decide on how to do it in less time than most people take to choose a good-sized flat screen from Best Buy. This talk describes the environment, the attack, the response and the choices made when a large enterprise has the opportunity to start anew - if you could replace every single thing in your environment tomorrow, and money was no object, what would you buy? How would you implement it? How would you train your organisation to use it, and change its culture from what you had - where IT, and particularly information security, clearly was not a consideration - to one in which IT and information security are trusted partners of the business? And how would you make sure that you never get into this situation again? If your answer doesn't affect what you do next year, you're not paying attention."
