Id: terraform-kubernetes-container-is-privileged
Provider: Kubernetes
Platform: Terraform
Severity: High
Category: Insecure Configurations
Learn More Description Minimize the admission of privileged containers. Privileged containers have elevated access to host resources and should be avoided where possible. This rule checks container and init_container entries in spec or spec.template.spec and flags any with security_context.privileged set to true.
