Description
Containers should be configured with a secure Seccomp profile to restrict potentially dangerous syscalls.
This rule validates that a seccomp profile is configured on kubernetes_pod, kubernetes_cron_job, and other workload resources. The recommended approach (Kubernetes v1.19+) is to set security_context.seccomp_profile.type to RuntimeDefault or Localhost in the pod spec. The legacy annotation seccomp.security.alpha.kubernetes.io/defaultProfileName with value runtime/default is also accepted for older clusters.
If neither the seccomp_profile block nor the annotation is configured, the rule reports a MissingAttribute issue. If seccomp_profile.type is set to an insecure value (e.g. Unconfined), the rule reports an IncorrectValue issue.
