Cloud & Kubernetes Security Embed security checks in CI/CD for container images, IaC, and Helm charts & contribute to runtime protections such as admission controls, policy-as-code, scanning, and drift detection. Promote secure infrastructure configurations and Kubernetes defaults (RBAC, network policies, PodSecurity, secrets handling, image provenance).
