This article describes connecting Amazon GuardDuty to Workbench.

Note

You need an AWS account with permissions to create and change IAM roles.

  1. We have an onboarding wizard that uses Cloudformation templates to perform all of the following steps in Workbench.

  2. If you prefer not to use the wizard, click Connect Manually to access the manual form and follow the instructions below.

  3. If you are using an Amazon GuardDuty Delegated Admin account, the following steps only need to be completed in that account. Only 1 device needs to be added to the Expel Workbench using the Delegated Admin account's primary region. If you are not using a Delegated Admin account, complete the following steps for each account you want monitored and add 1 device in Workbench per account.

Step 1: Create an AWS IAM policy

In this step, we create a permissions policy to assign to the IAM Role.

  1. Log into the AWS console and navigate to the IAM service.

  2. Go to Policies and click Create Policy.

  3. Add the following permissions using the JSON tab.

    {
       "Version": "2012-10-17",
        "Statement": [
            {
                "Sid": "VisualEditor0",
                "Effect": "Allow",
                "Action": [
                    "guardduty:GetFindings",
                    "guardduty:ListDetectors",
                    "ec2:DescribeRegions",
                    "guardduty:ListFindings",
                    "guardduty:GetDetector"
                ],
                 "Resource": "*"
            }      
        ]
    }
  4. Review and name the policy.

Step 2: Create an IAM role

Create an IAM role to connect to your Amazon GuardDuty Service.

  1. From within the IAM service, navigate to Roles and click Create Role.

  2. Select Another AWS account and fill out the required fields.

    • Account ID: 012205512454 (the ExpelAWS account ID).

    • External ID: Provided to you by Expel.

  3. Attach the IAM policy from Step 1 to the Role.

  4. Give the Role a name and click Create Role.

  5. Navigate to the role you just created and copy the following information for onboarding in Workbench.

    • Role ARN.

    • External ID Value on the Trust relationships tab.

Step 3: Onboard Amazon GuardDuty in Workbench

Note

Expel secures all login information our SOC analysts need about your devices in an MFA password product. Access to this login information is protected using our internal MFA processes. To learn more about the IP addresses all Expel traffic comes from, go here.

  1. In a new browser tab, login to https://workbench.expel.io/settings/security-devices?setupIntegration=aws_guardduty.

  2. The Add Security Device page for Amazon GuardDuty appears. Use the wizard or click Connect Manually to add your Amazon GuardDuty installation to Workbench manually.
