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
