Encrypt WorkSpaces root volume (C:drive for Windows and root for Amazon Linux) and user volume (D:drive for Windows and /home for Amazon Linux).
When you launch a WorkSpace, you can encrypt the root volume and the user volume. This ensures that the data stored at rest for WorkSpaces is encrypted.
You must encrypt a WorkSpace when it is launched. You cannot create a custom image from an encrypted WorkSpace. You cannot disable encryption once encryption is enabled for a WorkSpace. You must enable to AWS KMS CMK prior to rebuilding/rebooting an encrypted WorkSpace or it becomes unusable.
If the value listed in the Volume Encryption column is Disabled, the selected AWS WorkSpaces instance volumes are not encrypted.
aws workspaces describe-workspaces --region us-east-1 --output table --query 'Workspaces[*].WorkspaceId'

If the returned flag value for both root and user volumes is false (as shown in the output example above), the selected AWS WorkSpaces instance volumes are not encrypted.
If the selected AWS WorkSpaces instance volumes are not encrypted, refer to the remediation procedure below.
Both RootVolumeEncryptionEnabled and UserVolumeEncryptionEnabled should return true.
Login to the WorkSpaces console at https://console.aws.amazon.com/workspaces/
Click Launch WorkSpaces and complete the first three steps
For the WorkSpaces Configuration step, do the following:
Click Next Step
Click Launch WorkSpaces
NOTE: To encrypt existing AWS WorkSpaces data you must re-create the necessary WorkSpaces instances with the volumes encryption feature enabled as outlined above.
create-workspaces command:aws workspaces create-workspaces --workspaces DirectoryId='your_directoryID',
UserName='user_for_workspace',
BundleId='workspace_bundle_ID',
VolumeEncryptionKey='AWS_KMS_customer_master_key_(CMK)',
UserVolumeEncryptionEnabled='true',
RootVolumeEncryptionEnabled='true',
WorkspaceProperties={RunningMode='AUTO_STOP',
RunningModeAutoStopTimeoutInMinutes='10', RootVolumeSizeGib='root_GB',
UserVolumeSizeGib='user_GB', ComputeTypeName='STANDARD'}
By default, AWS Workspaces utilize Elastic Block Store (AWS EBS) by default to encrypt data at rest (https://docs.aws.amazon.com/workspaces/latest/adminguide/data-protection.html)
AWS Workspaces utilizes TLS 1.2 encryption and SigV4 request signing by default to encrypt data in transit. DCV, streaming and control data in-transit is encrypted using TLS 1.3 encryption for UDP traffic and TLS 1.2 encryption for TCP traffic, with AES-256 ciphers.
For DCV, streaming and control data in-transit is encrypted using TLS 1.3 encryption for UDP traffic and TLS 1.2 encryption for TCP traffic, with AES-256 ciphers.
