Amazon Cloud Drive is a remote file storage service from Amazon Inc.

This SonicWALL signature identifies legitimate HTTP Requests for Amazon Cloud Drive traffic. Please note, this signature will only work when DPI-SSL Client Inspection is enabled. This is because Amazon Cloud Drive HTTP requests are protected by SSL protocol. DPI-SSL CI is required to apply control to outgoing SSL connections.

If you do not want to enable DPI-SSL CI. You can block all HTTPS/SSL connections to Amazon by enabling the Amazon.com application signatures. This will block the HTTPS/SSL connections to all Amazon Services including Amazon.com, Amazon Web Services, Amazon Cloud Drive, etc.
