To ensure ongoing security site reliability engineers must work hand-in-hand with the CISO’s (Chief Information Security Officer) office to implement Kubernetes security. Running Kube-bench against cluster prior to production deployment allows engineers to configure Kubernetes settings and adjust manifests to harden the cluster itself.
