{/* MANUAL-CONTENT-START:intro */}
[AWS Identity and Access Management (IAM)](https://aws.amazon.com/iam/) is a web service that helps you securely control access to AWS resources. IAM lets you manage permissions that control which AWS resources users, groups, and roles can access.

With AWS IAM, you can:

- **Manage users**: Create and manage IAM users, assign them individual security credentials, and grant them permissions to access AWS services and resources
- **Create roles**: Define IAM roles with specific permissions that can be assumed by users, services, or applications for temporary access
- **Attach policies**: Assign managed policies to users and roles to define what actions they can perform on which resources
- **Organize with groups**: Create IAM groups to manage permissions for collections of users, simplifying access management at scale
- **Control access keys**: Generate and manage programmatic access key pairs for API and CLI access to AWS services

In Sim, the AWS IAM integration allows your workflows to automate identity management tasks such as provisioning new users, assigning roles and permissions, managing group memberships, and rotating access keys. This is particularly useful for onboarding automation, security compliance workflows, access reviews, and incident response — enabling your agents to manage AWS access control programmatically.
