IAM Least Privilege Patterns

To enforce least-privilege IAM for EKS, configure Kubernetes service accounts with IRSA-enabled IAM roles and scoped permission boundaries. This approach prevents privilege escalation and avoids embedding credentials directly in your workloads.

IAM permission boundaries are managed policies that set the maximum permissions an IAM role can have. Attaching them to roles prevents privilege escalation and ensures workloads cannot exceed their intended access scope.

Yes, you can implement least-privilege IAM and IRSA patterns using infrastructure as code tools like Terraform and CDK. These tools allow you to define scoped role policies and permission boundaries across your cloud infrastructure.

To avoid overly broad resources when configuring IAM roles, apply scoped permissions with specific resource ARNs and attach permission boundaries. You should also enable IAM Access Analyzer to validate access and record ownership with tags.

The best way to reduce IAM permission blast radius is enforcing least-privilege with scoped policies, IRSA for Kubernetes workloads, and permission boundaries. This limits access to only necessary actions and improves compliance.

Yes, IAM Access Analyzer supports validation for IRSA-enabled roles by reviewing resource access. Enabling it helps you identify overly broad resources and maintain least-privilege compliance across your cloud infrastructure.
