AWS deprecated this EKS auth method. 81% of clusters still run it.
The migration to Kubernetes and cloud native infrastructure has been one of the defining IT trends of the past decade. The post AWS deprecated this EKS auth method. 81% of clusters still run it. appeared first on The New Stack .
Amazon Web Services (AWS) has deprecated the legacy aws-auth ConfigMap for managing access control in Amazon EKS (Elastic Kubernetes Service) clusters. This change contrasts with AWS's security guidance, as a 2025 Kubernetes Security Report reveals that 81% of EKS clusters are still utilizing the older method. The persistence of the legacy method, contrary to AWS recommendations, underscores the security risks associated with manual, hard-to-audit configurations.
The importance of robust infrastructure spanning every container and node cannot be overstated, as underestimating the complexity can introduce significant vulnerabilities into cloud-native environments.
