Since no one can track all potential attack vectors for your Kubernetes cluster, the first and best defense is to always run the latest stable version of Kubernetes. In case vulnerabilities are found in running containers, it is recommended to always update the source image and redeploy the containers. Try to avoid direct updates to the running containers as this can break the image-container relationship. Bounded code example (external data; do not execute automatically): ```text Example: apt-update ``` Upgrading containers is extremely easy with the Kubernetes rolling updates feature - this allows gradually updating a running application by upgrading its images to the latest version.
