To help secure your AWS resources, follow these best practices for AWS Identity and Access Management (IAM)
| !.Requires Federation for human users: |
|---|
| Enable human users to access aws using temporary credentials obtained through federation with an identity provider. |
| 2.Use temporary Credentials with IAM roles: |
| Ensure workloads utilize temporary credentials obtained through IAM roles to access AWS resources. |
| 3.Implement MFA(Multifactor authentication) |
| Apply the use of MFA to add an extra layer of security for user authentication. |
| 4.Update Access keys when needed: |
| Regularly refresh access keys, especially for use cases requiring long-term credentials, to minimize security risks. |
| 5.Secure Root user credentials: |
| Follow best practices to protect the credentials of the root user, including enabling MFA for the root account. |
| 6.Apply Least-Privilege Permissions: |
| Grant users and processes the minimum permissions necessary to perform their tasks, reducing the risk of misuse. |
| 7.Start with AWS Managed Policies: |
| Begin with AWS managed policies and progressively move towards implementing least-privilege permissions. |
| 8.Utilize IAM Access Analyzer: |
| Utilize IAM Access Analyzer to generate least-privilege policies based on access activity and ensure secure permissions. |
| 9.Regularly review and remove unused resources: |
| Conduct regular reviews to identify and remove unused users, roles, permissions, policies and credentials. |
| 10.Use conditions in IAM Policies: |
| Improve access control by incorporating conditions in IAM policies to further restrict user access. |
| 11.Verify public and cross-account access: |
| Use IAM Access Analyzer to validate public and cross-account access to resources, ensuring security and compliance. |
| 12.Establish permissions guardrails: |
| Implement security policies across multiple AWS accounts to enforce consistent access controls. |
| 13.Delegate permissions boundaries: |
| Manage permissions within an account by setting up defined boundaries. |
By following these IAM best practices, you can greatly strengthen the security of your AWS environment, ensuring both secure and efficient access to resources.
