How to manually deploy a cross-account IAM role in AWS

The Cado platform can be configured to access resources across multiple AWS accounts. For example, if you manage multiple AWS accounts, you can deploy Cado in a single AWS account and grant access to the other accounts, enabling the platform to acquire, process, and analyze evidence seamlessly.

Alternatively, you can automatically deploy the IAM role via Stacksets, then add the roles to the Cado platform using AWS Organizations.

Overview​

The process below outlines how to grant the Cado platform access to a target AWS account (other than the one where Cado is deployed). This process can be repeated for every AWS account you want to provide access to.

There are two main steps to set up cross-account acquisitions:

  1. Create a Cross-Account IAM Policy and Role in the target AWS account from which the Cado platform will acquire data. This allows Cado to assume the cross-account role for data acquisition.
  2. Add the Cross-Account IAM Role ARN to the Cado platform to enable access to that AWS account.

This page describes step 1. For step 2, see Manually add a cross-account role to Cado.

info

Throughout this guide:

  • The primary AWS account is where Cado is deployed (referred to as account 111111111111).
  • The target AWS account is where cross-account access is being set up (referred to as account 222222222222).

Step 1: Create an IAM Policy and Role in the Target AWS Account​

  1. Create the IAM Policy:

    • In the target AWS account (222222222222), go to IAM > Policies and click Create Policy.
    • Use the Cado Cross-Account Policy found here.
    • Give the policy a name, such as CadoResponseCrossAccountPolicy, and create the policy.

  2. Create the IAM Role:

    • Navigate to IAM > Roles and click Create Role.
    • Select Another AWS Account and enter the account ID of your primary AWS account (111111111111).

    Create Role

    • Attach the policy created in the previous step and proceed to name the role.
    • The role name must include the text CadoResponse (e.g., CadoResponseCrossAccountRole). This is required for cross-account acquisition to function properly.
    • The role needs a trust relationship with the Cado role in 111111111111

Deploying the Cross-Account IAM Policy and Role can be automated using AWS StackSets or other methods. See Automating AWS IAM Role and Policy Deployment.
