This blog post looks at securing EKS clusters with pod security groups and network policies.To use this guide, the Cluster has been provisioned using Terraform and GitHub Actions.The process starts by configuring the bastion host using the Session Manager.The article goes on to define how to create security groups for the cluster and enforce policies that limit access based on these security groups.The article then details how to configure network policies in EKS to restrict traffic between different pods.The tutorial then focuses on pod identity management, which enables IAM roles to be assigned across clusters to groups of pods automatically.By the end of the process, pods can assume IAM Users that interact with AWS services as that User would interact.The article concludes by explaining how to define and test a policy that would allow a service account to interact with S3.This guide is useful for anyone managing or deploying applications on EKS and wants to ensure that security is a top priority.The guide provides commands and configuration examples for those looking to implement the policies outlined in the article.
