Cross-Account Access via CloudFormation

There are multiple ways to deploy AWS roles to provide Dropzone visibility into your environment. See the aws documentation for more info.

Dropzone provides CloudFormation Templates (CFTs) that assist you in creating the IAM Role you need to integrate with Dropzone. The new role includes a custom trust policy, an AWS-managed ReadOnlyAccess policy, and an inline policy granting specific permissions for secure and streamlined Dropzone operations.

There are two CFTs available:

Name	CFT Link	Purpose
ReadOnly	link	This policy provides read-only access to all your AWS resources. Use this if you do not want to edit your role if more permissions are required in the future.
Minimum ReadOnly	link	This policy provides read-only access to only those AWS resources currently needed by Dropzone. Use this if you are prepared to edit your Policies in the future if Dropzone adds new functionality that requires more access.

Both create a Custom Trust Policy that ensures secure role assumption by Dropzone, using the provided External ID and User ARN.

The current Minimum ReadOnly access list is as follows:

Policy
AWSCloudTrail_ReadOnlyAccess
AmazonEC2ReadOnlyAccess
AmazonGuardDutyReadOnlyAccess
AmazonRoute53ReadOnlyAccess
AmazonS3OutpostsReadOnlyAccess
AmazonS3ReadOnlyAccess
AmazonSSMReadOnlyAccess
IAMReadOnlyAccess

Running the CloudFormation Template

You will need to repeat these instructions for each account you want visible to Dropzone.

• Log into your AWS account

• Go to the CloudFromation console, https://console.aws.amazon.com/cloudformation/

• Click on "Create Stack" > "With new resources (standard)"

Create Stack Button

If this is your first stack, then the option will not have "With new resources"

• In the "Prerequisite - Prepare template" select "Choose an exiting template"

• In the "Specify template" section

  • Select "Amazon S3 URL"

  • In the "Amazon S3 URL" field paste the link to the CFT you've chosen to use (e.g. ReadOnly) from the table at the top of this document

Template specification

• Click "Next"

• Enter a "Stack name", e.g. "Dropzone-AI"

Stack Name

• In the Parameters section fill out the information you gathered from the Dropzone UI

Stack Paramaters

• Click "Next"

• On the "Configure stack options" page click "Next"

• On the "Review and create" page click "Submit"

Create the stack via the Submit button

• Once the stack creation is complete, click Outputs

• Record the value for the RoleARN for use later in the Dropzone UI where it will be known as "Role ARNs"

Output Role ARN

• Repeat for additional AWS accounts

Once done, you may move onto configuring the Dropzone Data and Alert Sources described in the aws documentation
