The hostPath mapping-based volumes require special attention, as the same path can be used by different workloads and lead to data exposure or corruption. It should be noted that some volumes are actually stored on the Kubernetes worker node’s file system. Additionally, ARMO runtime security allows you to choose what part of the file system should be encrypted, based on the individual files, folders, files types, and more sophisticated naming convention methods. It is managed through custom storage classes and storage drivers, which are up to the cluster administrator to create and are often specific to the platform on which Kubernetes is running. ARMO Kubescape will help identify all the containers that violate this rule.īoth ephemeral and persistent volumes can be encrypted however, this is outside the domain of Kubernetes itself. For example, it is always recommended to map the container file system as read-only. Then, you should make sure that everything that requires only reading rights is read-only. For example, it may turn a read/write volume into read-only.Īs far as the security of the volume is concerned, the first action to perform is to ensure that volumes are mapped only to workloads that really need them. CSI can also serve as a filter to other volumes. It allows, for example, creating a volume that is backed by an Object Store such as AWS S3.

This mechanism utilizes the Linux FUSE feature and requires a CSI driver to be installed on the node prior to the volume claim. Dynamic provisioning creates volumes when persistent volume claims are made it is often used when Kubernetes is running on a cloud platform.Īnother way to create a volume is via Container Storage Interface (CSI). Static provisioning requires the system administrator to pre-create volumes and makes them available to the cluster persistent volume claims will be mapped to these pre-existing volumes. Mounted volumes can be either ephemeral or persistent, and Kubernetes offers both.įor persistent v olumes, Kubernetes offers static or dynamic provisioning.

VolumesĪt the level of the operating system, files are stored on filesystems, either on the filesystem of the container itself or on a mounted volume. Note that from the storage access and security perspectives, the Object store items and the Platform service databases are almost identical, so we will address them together.

In this article, we will review how to deal with each of these data types in a Kubernetes cluster. There are different types of stored data in Kubernetes: Whatever the case may be, you will most likely need to have a look at data-how to store it and how to secure it. If you’re reading this article, you’re probably either running a Kubernetes cluster or planning to run one.
