Session + Live Q&A

Application-Layer Encryption Basics for Developers

Application-layer encryption should be a tool in every developer's toolbox. In this talk, I cover the basics of encryption, what are application-layer and infrastructure-layer encryption, when to use asymmetric and symmetric keys, and how to do key management. Finally, we review a complete code example for simple encryption and key management. This talk can be a jumping-off point for developers looking to add encryption to their systems, and for my previous QCon talk and material that teach encryption for developers.

Depending On If I Had Coffee Or Not Your Application May Be High Risk

Thursday May 20 / 10:10AM EDT

Security practitioners are often espresso'ing risk with qualitative measurements. We use broad, imprecise risk measurements such as high, medium, and low while applying them inconsistently if we haven't had our first cup. We struggle to measure if security work is driving down risk,...
