How to lose a container in 10 minutes

Despite the fact that many organisations are already using/wanting to use containers and quite possibly moving to the cloud at the same time, I find that there is still an inherent lack of understanding from both devs and security teams as to how containerised applications should be designed and run. Many teams simply try to run a containerised application like it would be run on a virtual machine or in the traditional monolithic application stack, and to accompany that they use the traditional security toolset. This opens up the potential for security breaches and or simply an ineffective application that doesn’t take advantage of the benefits containerised environments provide. As I’m conscious this could be a bit of dry topic and I don’t want it to sound like a lecture, my talk has many GIFs and memes and real life examples (they are redacted as I can’t name where I saw some of these, unfortunately). More seriously though, it includes relevant stories and was developed with input from my real-life experiences and some stories from other engineers and security professionals. I’ve been spinning up different types of containers and leaving them open to the web to see what happens i.e. can I actually get myself pwned? A brief summary of the talk structure: Introduction to myself and the talk Overview of cloud-native services and containers Encryption and containers Isolating containers Structuring containerised applications Orchestrator configuration Using good container images Running as root in the container Secret/credentials storage Deploying containers ephemerally Shifting security to the left Deploying a container-aware security toolset What happened when I tried to get my containers pwned Summary and close
