While the [Cloud Native Computing Foundation][cloud-native-computing-foundation] (CNCF) owns and maintains most of the code running in AKS, Microsoft takes responsibility for building the open-source packages that we deploy on AKS. With that responsibility, it includes having complete ownership of the build, scan, sign, validate, and hotfix process and control over the binaries in container images. By us having responsibility for building the open-source packages deployed on AKS, it enables us to both establish a software supply chain over the binary, and patch the software as needed.

Microsoft is active in the broader Kubernetes ecosystem to help build the future of cloud-native compute in the wider CNCF community. This work not only ensures the quality of every Kubernetes release for the world, but also enables AKS quickly get new Kubernetes releases out into production for several years. In some cases, ahead of other cloud providers by several months. Microsoft collaborates with other industry partners in the Kubernetes security organization. For example, the Security Response Committee (SRC) receives, prioritizes, and patches embargoed security vulnerabilities before they're  announced to the public. This commitment ensures Kubernetes is secure for everyone, and enables AKS to patch and respond to vulnerabilities faster to keep our customers safe. In addition to Kubernetes, Microsoft has signed up to receive pre-release notifications for software vulnerabilities for products such as Envoy, container runtimes, and many other open-source projects.

Nightly, we apply security updates to the OS on the node, but the node image used to create nodes for your cluster remains unchanged. If a new Linux node is added to your cluster, the original image is used to create the node. This new node receives all the security and kernel updates available during the automatic assessment performed every night, but remains unpatched until all checks and restarts are complete. You can use node image upgrade to check for and update node images used by your cluster. For more information on node image upgrade, see [Azure Kubernetes Service (AKS) node image upgrade][aks-node-image-upgrade].

AKS patches CVE's that has a *vendor fix* every week. CVE's without a fix are waiting on a *vendor fix* before it can be remediated. The fixed container images are cached in the next corresponding Virtual Hard Disk (VHD) build, which also contains the updated Ubuntu/Azure Linux/Windows patched CVE's. As long as you're running the updated VHD, you shouldn't be running any container image CVE's with a vendor fix that is over 30 days old.

For the OS-based vulnerabilities in the VHD, AKS uses **Unattended Update** by default, so any security updates should be applied to the existing VHD's daily. If **Unattended Update** is disabled, then it's a recommended best practice that you apply a Node Image update on a regular cadence to ensure the latest OS and Image security updates are applied.
