Apply Security Context to Your Pods and Containers

Apply Security Context to Your Pods and Containers. 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.

GSL LOGIC

KubernetesPod should have spec.containers contain-all [ securityContext ] and (spec.initContainers isEmpty() or spec.initContainers contain-all [ securityContext ])

REMEDIATION

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.

Pods

Pods are the smallest deployable units of computing that can be created and managed in Kubernetes.A Pod is a group of one or more containers (such as Docker containers), with shared storage/network, and a specification for how to run the containers.
