AWS provides services that allow data to be encrypted at rest and in-transit and other granular security controls and auditing mechanisms. In addition, customer data is wrapped to a physical Nitro Security Key. Destroying the device is equivalent to destroying the data.  As part of the shared responsibility model, customers are responsible for attesting to physical security and access controls around the Outpost, as well as environmental requirements for facility, networking, and power as published here. Prior to returning the Outposts rack hardware, the Nitro Security Key will be removed to ensure customer content is crypto shredded.
