How To: Create a Fugue IAM Role¶
This quick tutorial shows how to create the Fugue IAM role to scan an AWS or AWS GovCloud environment by launching a CloudFormation stack in your AWS account.
See a list of all possible IAM permissions here.
What’s Going to Happen?¶
When you launch a stack to create an IAM role in your account, Fugue creates the role with permissions according to the resource types you selected. It assigns two policies:
The AWS-managed SecurityAudit read-only policy
Note that the role also has a trust policy that specifies an external ID. Fugue generates this unique ID for you to prevent other parties from assuming the role without the ID, even if they have your role ARN.
After you’ve named your environment and selected your resources in the Create New Environment workflow, you’ll arrive at the permissions page:
Launch CloudFormation Stack¶
Select Review Stack in AWS Console.
Select Next on the next three pages, keeping defaults.
Check the box to acknowledge that CloudFormation may create IAM resources with custom names.
Select Create Stack.
On the created stack page, select the Outputs tab.
Copy the IAM role ARN from the Value column after it appears (this may take a few seconds and require refreshing).
Paste the IAM role ARN in the AWS IAM Role ARN field in Fugue.
That’s it – you’re done! You just created an IAM role for Fugue.
How do I see the role permissions before creating the role?¶
You can inspect the exact permissions Fugue will grant the role by viewing the CloudFormation stack template. To do so, click the view template link in the Create New Environment workflow:
You’ll see a modal containing the CloudFormation template Fugue generated for you based on the resource types you selected for scanning. The template includes the AWS-managed read-only SecurityAudit policy and a tightly-scoped supplemental policy to cover any additional permissions.
