name: EKS Kubernetes Secrets not Encrypted

description: |
|
|
Ensure that your Amazon Elastic Kubernetes Service (EKS) clusters have encryption enabled for Kubernetes secrets using AWS KMS Customer Master Keys (CMKs). This is a security best practice for protecting sensitive data stored in Kubernetes secrets.
|
|
impact: |
|
|
Without encryption enabled, Kubernetes secrets are stored in plaintext, making them vulnerable to unauthorized access and potentially violating compliance requirements for data-at-rest encryption.
|
|
remediation: |
|
|
Enable encryption for your EKS cluster by creating a KMS CMK and configuring it for the cluster. Note that this requires recreating the cluster with the encryption configuration.
