Ingesting Cloud Assets from AWS requires a Cortex XDR Pro per TB license.
Cortex XDR provides a unified, normalized asset inventory for cloud assets in AWS. This capability provides deeper visibility to all the assets and superior context for incident investigation.
To receive cloud assets from AWS, you must configure the Collection Integrations settings in Cortex XDR using the Cloud Inventory data collector to configure the AWS wizard. The AWS wizard includes instructions to be completed both in AWS and the AWS wizard screens. After you set up data collection, Cortex XDR begins receiving new data from the source.
As soon as Cortex XDR begins receiving cloud assets, you can view the data in → , where All Assets and Specific Cloud Assets pages display the data in a table format.
To configure the AWS cloud assets collection in Cortex XDR.
Open the AWS wizard in Cortex XDR.
Select→ → → .
In the Cloud Inventory configuration, click Add Instance to begin a new configuration.
Define the Account Details screen of the wizard.
Setting the connection parameters on the right-side of the screen is dependent on certain configurations in AWS as explained below.
Select the Organization Level as either Account (default), Organization, or Organization Unit. The Organization Level that you select changes the instructions and fields displayed on the screen.
Sign in to your AWS master account.
Create a stack called XDRCloudApp using the preset Cortex XDR template in AWS.
The following details are automatically filled in for you in the AWS CloudFormation stack template.
Stack Name—The default name for the stack is XDRCloudApp.
CortexXDRRoleName—The name of the role that will be used by Cortex XDR to authenticate and access the resources in your AWS account.
External ID—The Cortex XDR Cloud ID, a randomly generated UUID that is used to enable the trust relationship in the role's trust policy.
To create the stack, accept the IAM acknowledgment for resource creation by selecting the I acknowledge that AWS CloudFormation might create IAM resources with custom names checkbox, and click Create Stack.
Wait for the Status to update to CREATE_COMPLETE in the Stacks page that is displayed, and select the XDRCloudAPP stack under the Stack name column in the table.
Select the Outputs tab and copy the Value of the Role ARN.
Paste the Role ARN value in one of the following fields in the Account Details screen in Cortex XDR. The field name is dependent on the Organization Level that you selected.
Account—Paste the value in the Account Role ARN field.
Organization—Paste the value in the Master Role ARN field.
Organization Unit—Paste the value in the Master Role ARN field.
Set the Root ID in Cortex XDR.
This step is only relevant if you’ve configured the Organization Level as Organization in the Account Details screen in Cortex XDR. Otherwise, you can skip this step if the Organization Level is set to Account or Organization Unit.
From the main menu of the AWS Console, select→ .
Copy the Root ID displayed under the Root directory and paste it in the Root ID field in the Account Details screen in Cortex XDR.
Set the Organization Unit ID in Cortex XDR.
This step is only relevant if you’ve configured the Organization Level as Organization Unit in the Account Details screen in Cortex XDR. Otherwise, you can skip this step if the Organization Level is set to Account or Organization.
On the main menu of the AWS Console, select your username, and then My Organization.
Select the Organization Unit with an icon-ou () beside it in the organizational structure that you want to configure.
Copy the ID and paste it in the Organization Unit ID field in the Account Details screen in Cortex XDR.
Define the following remaining connection parameters in the Account Details screen in Cortex XDR.
Account Role External ID / Master External ID—The name of this field is dependent on the Organization Level configured. This field is automatically populated with a value. You can either leave this value or replace it with another value.
Cortex XDR Collection Name—Specify a name for your Cortex XDR collection that is displayed underneath the Cloud Inventory configuration for this AWS collection.
Define the Configure Member Accounts screen of the wizard.
This wizard screen is only displayed if you’ve configured the Organization Level as Organization or Organization Unit in the Account Details screen in Cortex XDR. Otherwise, you can skip this step when the Organization Level is set to Account.
Configuring member accounts is dependent on creating a stack set and configuring stack instances in AWS, which can be performed using either the Amazon Command Line Interface (CLI) or Cloud Formation template via the AWS Console. Both of these methods are explained in the instructions below.
Define the account credentials using Amazon CLI.
Select the Amazon CLI tab, which is displayed by default.
Open the Amazon CLI.
For more information on how to set up the AWS CLI tool, see the AWS Command Line Interface Documentation.
Run the following command to create a stack set, which you can copy from the Configure Member Accounts screen by selecting the copy icon (), and paste in the Amazon CLI. This command includes the Role Name and External ID field values configured from the wizard screen.
aws cloudformation create-stack-set --stack-set-name StackSetCortexXdr01 --template-url https://cortex-xdr-xcloud-onboarding-scripts-dev.s3.us-east-2.amazonaws.com/cortex-xdr-xcloud-master-dev-1.0.0.template --permission-model SERVICE_MANAGED --auto-deployment Enabled=true,RetainStacksOnAccountRemoval=true --parameters ParameterKey=ExternalID,ParameterValue=c9a7024c-3f07-40ed-a4fb-c3a5eba778e2 --capabilities CAPABILITY_NAMED_IAM
Run the following command to add stack instances to your stack set, which you can copy from the Configure Member Accounts screen by selecting the copy icon (), and paste in the Amazon CLI. For the
--deployment-targetsparameter, specify the organization root ID to deploy to all accounts in your organization, or specify Organization Unit IDs to deploy to all accounts in these Organization Units. In this parameter, you will need to replace
<Region>according to your AWS settings.
aws cloudformation create-stack-instances --stack-set-name StackSetCortexXdr01 --deployment-targets OrganizationalUnitIds='["<Org_OU_ID1>", "<Org_OU_ID2>"]' --regions '["<Region>"]'
In this example, the Organization Units are populated with
aws cloudformation create-stack-instances --stack-set-name StackSet_myApp --deployment-targets OrganizationalUnitIds='["ou-rcuk-1x5j1lwo", "ou-rcuk-slr5lh0a"]' --regions '["eu-west-1"]'
Once completed, in the AWS Console, select→ → , and you can see the StackSet is now listed in the table.
Define the account credentials using AWS CloudFormation.
Select the Cloud Formation tab.
Download the CloudFormation template. The name of the file downloaded is called
Sign in to your AWS Master Account using the AWS console, select → → , and click Create StackSet.
Define the following settings.
-Select Template is ready.
-Select Upload a template file, Choose file, and select the CloudFormation template that you downloaded.
Define the following settings.
-StackSet name—Specify a name for the StackSet.
ExternalID—The ExternalID value specified here must be copied from the one populated in the External ID field on the right-side of the Configure Member Accounts screen in Cortex XDR .
