Talk - 'Deep-dive into Containers and How to Secure Them'
Containers are a fundamental building block for modern applications, but they bundle a large amount of third-party code. Identifying what’s inside an image (and which versions) is critical for security. This post summarises a January 2025 presentation at Defcon 44131 covering how containers work, why SCA (Software Composition Analysis) matters, common open-source tooling (Syft/Grype, Trivy, Docker Scout, Clair) and an introduction to Konarr — an SCA platform focused on containers. It closes with pragmatic steps to reduce risk: scan early, monitor continuously, patch often, and shrink the attack surface.
