Resolves CIS benchmark rule 5.7.3, Pods part. SecurityContext should be explicitly defined in pod level of Pod spec section. It is sufficient to specify empty securityContext to satisfy CIS 5.7.3 rule. 5.7.3 Apply Security Context to Your Pods and Containers When designing your containers and pods, make sure that you configure the security context for your pods, containers, and volumes.
