Next steps and resources
Now that you understand how to implement secure access controls by using certificate attributes with AWS Identity and Access Management Roles Anywhere, consider reviewing your existing hybrid workload architectures. Identify workloads that currently use long-term credentials or require secure access to AWS resources from outside of the AWS Cloud. Evaluate opportunities to enhance security by implementing certificate-based authentication and applying the fine-grained access controls described in this guide. Consider starting with a small proof of concept before expanding to production workloads. Validate that certificate attributes and trust policies align with your security requirements and organizational structure.
For new accounts and workloads, incorporate these recommendations from the design phase. Use the sample configurations and policies provided in this guide as a foundation. You can adapt them to your specific use cases while maintaining the principle of least privilege. If you need additional guidance or have specific questions about implementing IAM Roles Anywhere in your environment, contact your AWS account team or AWS Professional Services.
