Security in Kubernetes does not have to be an expert-only discipline.

Abhishek Rao shares a simple mental model for platform security: layer access and isolation step by step, just like physical security in a building. The point is not perfect complexity, but practical controls teams can actually adopt.

When security feels understandable, adoption becomes realistic.

Alessandro Pomponio, Research Software Engineer @ IBM Research, explains how his team used Kyverno policies to solve GPU resource monopolization in their Kubernetes clusters. He describes a common anti-pattern where researchers were creating idle pods with commands like sleep infinity and using SSH to treat them as virtual machines, causing GPU starvation for other users, especially during conference deadlines.

Alessandro walks through their policy-based solution using Kyverno to block pod exec commands while maintaining necessary exceptions for cluster administrators.
