# aws\_iam\_user
|
|
|
|
Use the `aws_iam_user` Chef InSpec audit resource to test properties of a single AWS IAM user.
|
|
|
|
To test properties of more than one user, use the `aws_iam_users` resource.
|
|
|
|
To test properties of the special AWS root user (which owns the account), use the `aws_iam_root_user` resource.
