5.7.3 Apply Security Context to Your Pods and Containers

Information

Apply Security Context to Your Pods and Containers

Rationale:

A security context defines the operating system security settings (uid, gid, capabilities, SELinux role, etc..) applied to a container. When designing your containers and pods, make sure that you configure the security context for your pods, containers, and volumes. A security context is a property defined in the deployment yaml. It controls the security parameters that will be assigned to the pod/container/volume. There are two levels of security context: pod level security context, and container level security context.

Impact:

If you incorrectly apply security contexts, you may have trouble running the pods.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

Follow the Kubernetes documentation and apply security contexts to your pods. For a suggested list of security contexts, you may refer to the CIS Security Benchmark for Docker Containers.

Default Value:

By default, no security contexts are automatically applied to pods.
