Fuzzing is an effective method for finding security bugs, but getting results is tricky because it needs expertise, machine power, and process changes to deploy. "Project Springfield" packages Microsoft's best practices, combined with a decade of research into machine reasoning and "Whitebox fuzzing," into a cloud service that makes it easy to rapidly deploy fuzzing across an organization. Come hear how Microsoft customers and internal teams have embraced the cloud to gain scale, speed, and unique technology for finding serious security bugs -- and how you can do he same. Learn lessons from building and operating a fuzzing platform that aims to help everyone, everywhere, test their security critical code. The talk will start with an overview of the Project Springfield cloud platform, including a demonstration of the web front end and an SDK for integration. The talk will then focus on a guided discussion of future directions for fuzzing - we want to hear from attendees what they need and what would work for them! Attendees will come away with a Project Springfield account to let them experiment with cloud fuzzing at home.
