As the Kubernetes ecosystem matures, so do the threats targeting its software supply chain—from insecure container images to misconfigured workloads and unverified deployments. This talk dives into how platform and DevOps engineers can implement real-time, in-cluster controls to secure their Kubernetes environments beyond the CI pipeline.

We’ll walk through practical, production-ready implementations of:
1. Cosign for signing and verifying container images
2. Kyverno for applying policy-as-code and enforcing trusted sources
3. OPA (Open Policy Agent) for fine-grained admission controls and compliance
4. How to combine these tools to detect, prevent, and respond to supply chain risks at deploy time

The session includes live examples of rejecting unsigned images, enforcing namespace-specific rules, verifying image provenance, and layering policies for secure multi-team clusters. Attendees will leave with a clear blueprint for securing software delivery pipelines from build to cluster.
