Overview In modern cloud architectures, the old model of a secure perimeter with a trusted internal network is obsolete. A Zero Trust approach, which assumes no traffic is safe by default, is now the standard for robust security. This principle is especially critical when managing traffic within your AWS environment, where Elastic Load Balancers (ELBs) […]

Overview In AWS environments, the Classic Load Balancer (CLB) remains a key component for distributing traffic, especially in legacy or multi-tier architectures. However, its effectiveness hinges on a critical configuration: the health check protocol. A common misconfiguration is to rely on a simple Transport Layer (TCP) health check, which only verifies that a network port […]

Overview In AWS, the security of your container orchestration layer is a shared responsibility. While Amazon Elastic Kubernetes Service (EKS) manages the control plane, securing the data plane—specifically the EC2 worker nodes—is critical. A common and dangerous misconfiguration involves granting excessive permissions to the Identity and Access Management (IAM) roles attached to these worker nodes. […]

Overview In any AWS cloud environment, network security is a foundational pillar of governance and cost management. For organizations running containerized workloads on Amazon Elastic Kubernetes Service (EKS), the configuration of security groups is a critical control point. An AWS Security Group acts as a stateful virtual firewall for your EKS cluster, dictating precisely what […]

Overview Amazon Elastic Kubernetes Service (EKS) provides a managed control plane, simplifying the deployment and scaling of containerized applications on AWS. However, this managed service does not eliminate the organization’s responsibility for lifecycle management. A critical aspect of this responsibility is ensuring that all EKS clusters are running on a currently supported version of Kubernetes. […]
