Analyze vulnerabilities in Amazon EKS

Security is a critical consideration for configuring and maintaining Kubernetes clusters and applications. The following lists resources for you to analyze the security configuration of your EKS clusters, resources for you to check for vulnerabilities, and integrations with AWS services that can do that analysis for you.

The Center for Internet Security (CIS) benchmark for Amazon EKS

The Center for Internet Security (CIS) Kubernetes Benchmark provides guidance for Amazon EKS security configurations. The benchmark:

  • Is applicable to Amazon EC2 nodes (both managed and self-managed) where you are responsible for security configurations of Kubernetes components.

  • Provides a standard, community-approved way to ensure that you have configured your Kubernetes cluster and nodes securely when using Amazon EKS.

  • Consists of four sections; control plane logging configuration, node security configurations, policies, and managed services.

  • Supports all of the Kubernetes versions currently available in Amazon EKS and can be run using kube-bench, a standard open source tool for checking configuration using the CIS benchmark on Kubernetes clusters.

To learn more, see Introducing The CIS Amazon EKS Benchmark.

Amazon EKS platform versions

Amazon EKS platform versions represent the capabilities of the cluster control plane, including which Kubernetes API server flags are enabled and the current Kubernetes patch version. New clusters are deployed with the latest platform version. For details, see View Amazon EKS platform versions for each Kubernetes version.

You can update an Amazon EKS cluster to newer Kubernetes versions. As new Kubernetes versions become available in Amazon EKS, we recommend that you proactively update your clusters to use the latest available version. For more information about Kubernetes versions in EKS, see Understand the Kubernetes version lifecycle on EKS.
