Data encryption for FSx for Windows File Server volumes

FSx for Windows File Server supports two forms of encryption for file systems. They are encryption of data in transit and encryption at rest.

Amazon FSx automatically encrypts data in transit using SMB encryption as you access your file system without the need for you to modify your applications.

Use Windows ACLs for folder level access control

The Windows Amazon EC2 instance access Amazon FSx file shares using Active Directory credentials. It uses standard Windows access control lists (ACLs) for fine-grained file-level and folder-level access control. You can create multiple credentials, each one for a specific folder within the share which maps to a specific task.

In the following example, the task has access to the folder App01 using a credential saved in Secrets Manager. Its Amazon Resource Name (ARN) is 1234.

"rootDirectory": "\\path\\to\\my\\data\App01", "credentialsParameter": "arn-1234", "domain": "corp.fullyqualified.com",

In another example, a task has access to the folder App02 using a credential saved in the Secrets Manager. Its ARN is 6789.

"rootDirectory": "\\path\\to\\my\\data\App02", "credentialsParameter": "arn-6789", "domain": "corp.fullyqualified.com",
