Kubernetes: Prevent Service Account Impersonation Abuse with Fine-Grained RBAC
Preventing Service Account Impersonation Abuse with Fine-Grained RBAC in Kubernetes Preventing Service Account Impersonation Abuse with Fine-Grained RBAC in Kubernetes Service account impersonation is a serious security vulnerability in Kubernetes. By default, all service accounts can impersonate any pod within the same namespace. This allows a compromised service account to gain access to resources it…
