Minimize access to create pods

MoyenneNiveau 1Revue manuelleeks

Description

The ability to create Pods in EKS is a high-risk permission that should be limited to approved deployment and operational functions. In EKS, Pod creation can be granted through associated access policies or native Kubernetes RBAC, and policies such as AmazonEKSAdminPolicy and AmazonEKSEditPolicy include create access on pods. The benchmark marks this recommendation Manual.

Cette recommandation ne peut pas être vérifiée automatiquement. Une analyse la liste avec ces instructions lorsque vous passez --include-manual.

Begin by reviewing every path that can grant the ability to create Pods in EKS. Start with access entries and associated access policies, because AmazonEKSAdminPolicy and AmazonEKSEditPolicy include create access for pods. Then review Kubernetes RBAC, service accounts, and Pod security controls, because Pod creation can allow an identity to launch workloads under available service accounts and potentially exercise both Kubernetes and AWS permissions.

Méthode de correction

Méthode de correction: Recommandation ou correctif d'infrastructure

Start by reducing every access path that allows Pod creation in EKS. Start with access entries and associated access policies, because AmazonEKSAdminPolicy and AmazonEKSEditPolicy include create access for pods, and access policies can be scoped to the cluster or to specific namespaces. Then reduce unnecessary permissions in Kubernetes RBAC, service accounts, and Pod security controls so Pod creation is limited to approved deployment paths and the smallest practical workload boundary. • Remove or narrow access policy associations that allow Pod creation, and prefer namespace-scoped access over cluster-wide scope wherever possible. • Replace broad RBAC permissions on pods, deployments, daemonsets, statefulsets, jobs, and cronjobs with the smallest Role or ClusterRole that supports the approved function.
