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.
