ISC2 Security Congress, 4416 – GBU Slides

RattlesnakeMy presentation on the good, the bad, and the ugly about crowdsourced security continues to evolve. The title, of course, references Sergio Leone’s epic western. But the presentation isn’t a lazy metaphor based on a few words of the movie. The movie is far richer than that, showing conflicting motivations and shifting alliances.

The presentation is about building alliances, especially when you’re working with crowds of uncertain trust or motivations that don’t fully align with yours. It shows how to define metrics and use them to guide decisions.

Ultimately, it’s about reducing risk. Just chasing bugs isn’t a security strategy. Nor is waiting for an enumeration of vulns in production a security exercise. Reducing risk requires making the effort to understand what what you’re trying to protect, measuring how that risk changes over time, and choosing where to invest to be most effective at lowering that risk. A lot of this boils down to DevOps ideals like feedback loops, automation, and flexibility to respond to situations quickly. DevOps has the principles to support security, it should have to knowledge and tools to apply it.
