Configuring IAM Roles in AWS

Britive needs the following access permissions in the AWS IAM role to connect to AWS successfully:

IAM ReadOnly Access
AWSOrganization ReadOnly Access

Note:

Only read-only access is needed here as the role is mainly used for scanning in Britive. Hence, write access is not required for the role.

5. Click Next.
6. Enter the following on the Add Permissions page:
  1. Search for IAMReadOnlyAccess in Filter policies.
  2. Select IAMReadOnlyAccess.
  3. Search for AWSOrganizationsReadOnlyAccess in Filter policies.

         "Principal":{
            "Federated":"arn:aws:iam::<account>:saml-provider/Britive"
         },
         "Action":[
            "sts : AssumeRolewithSAML",
            "sts : SetSourceIdentity"
         ],
         "Condition":{
            "StringEquals":{

            }
         }
      }
   ]
}
```
  4. Click Create role. A message is displayed that the role is created.
You can select the newly created IAM role from the role list for the AWS account and view the role details on the Summary page. Note that the maximum session duration value displayed on the summary page is used when configuring the role properties within the Britive tenant.

Now that you have completed the onboarding prerequisites, you can choose to onboard AWS applications or AWS standalone applications per your requirement, and proceed with the onboarding process.
