Overview In any AWS cloud-native architecture, the integration between Amazon Elastic Kubernetes Service (EKS) and Amazon Elastic Container Registry (ECR) is a critical security boundary. EKS worker nodes must pull container images from ECR to launch application workloads, a process governed by AWS Identity and Access Management (IAM) roles. A frequent and dangerous misconfiguration is […]

Overview The control plane is the operational core of any Amazon Elastic Kubernetes Service (EKS) cluster, and the Kubernetes API server is its front door. This API server processes every administrative command, orchestrates container lifecycles, and manages the cluster’s state. By default, EKS cluster endpoints can be configured with public access, exposing this critical control […]

Overview In modern cloud-native architectures, perimeter security is no longer sufficient. For organizations running containerized workloads on Amazon Elastic Kubernetes Service (EKS), a critical security gap often exists by default: the internal network is completely open. By default, every pod within an EKS cluster can communicate with every other pod, creating a flat, unrestricted network. […]

Overview For years, managing user access to Amazon Elastic Kubernetes Service (EKS) clusters involved a delicate and often opaque process centered around the aws-auth ConfigMap. This file-based system bridged AWS Identity and Access Management (IAM) with Kubernetes’ native Role-Based Access Control (RBAC), but it created significant governance gaps, operational risks, and security blind spots. To […]

Overview In a modern cloud-native architecture, workloads running on Amazon Elastic Kubernetes Service (EKS) frequently need to interact with other AWS services like S3 buckets, DynamoDB tables, or Secrets Manager. Establishing a secure and auditable method for these interactions is a critical governance challenge. Historically, teams resorted to insecure practices, such as granting broad permissions […]
