# Identity and access management for Infrastructure Performance
<a name="identity-access-management"></a>

AWS Identity and Access Management (IAM) is an AWS service that helps an administrator securely control access to AWS resources. IAM administrators control who can be *authenticated* (signed in) and *authorized* (have permissions) to use Infrastructure Performance resources. IAM is an AWS service that you can use with no additional charge.

To use Infrastructure Performance, you'll need an AWS account and AWS credentials. To increase the security of your AWS account, we recommend that you use an IAM user to provide access credentials instead of using your AWS account credentials. For more information, see [AWS security credentials](https://docs.aws.amazon.com/IAM/latest/UserGuide/security-creds.html) and [Security best practices in IAM](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html) in the *IAM User Guide*.

The following sections provide details on how an IAM administrator can use IAM to help secure your AWS resources, by controlling who can perform Infrastructure Performance actions.
