This talk will clarify different aspects of a modern computer architecture, with emphasis in the Intel-based platforms, but with an open-mindset. It will define the threats that exist, processes in place, new (and upcoming) security features and pinpoint difficulties protecting computer networks. As usual, Rodrigo will also face the FUD around misplaced news explaining hardware-based backdoors, their power and easy to spot and proposing ways for companies to protect Virtualized environments and avoid supply chain hijacks (all the NSA-related jokes will be part of the talk and not of the Abstract since Rodrigo is currently living in US). If you don’t know a lot about your computer and how it works, this talk is for you. If you do, this talk will challenge your knowledge and hopefully will have one (or five) things you didn’t knew before.
