Downloading Account IAM Details

Downloading Account Authorization Details

We can scan an entire AWS account and generate reports. To do this, we leverage the AWS IAM get-account-authorization-details API call, which downloads a large JSON file (around 100KB per account) that contains all of the IAM details for the account. This includes data on users, groups, roles, customer-managed policies, and AWS-managed policies.

  • You must have AWS credentials configured that can be used by the CLI.

  • You must have the privileges to run iam:GetAccountAuthorizationDetails. The arn:aws:iam::aws:policy/SecurityAudit policy includes this, as do many others that allow Read access to the IAM Service.

  • To download the account authorization details, ensure you are authenticated to AWS, then run cloudsplaining's download command:

cloudsplaining download
  • If you prefer to use your ~/.aws/credentials file instead of environment variables, you can specify the profile name:
cloudsplaining download --profile myprofile

It will download a JSON file in your current directory that contains your account authorization detail information.
