![]() ![]() Devices that fail to complete the clear are successfully degaussed (for magnetic media only), multi-pin punched (for chipped based boards such as SSDs), or destroyed. Records are kept of the erasure and destruction of assets. ![]() Purge and destroy sanitization is performed using tools and processes approved by the Security Group. Destroy: renders target data recovery infeasible using state-of-the-art laboratory techniques and results in the subsequent inability to use the media for storage of data.Purge: relates to physical or logical techniques that render target data recovery infeasible using state-of-the-art laboratory techniques.These are techniques typically applied through the standard read and write commands to the storage device, such as by rewriting with a new value or using a menu option to reset the device to the factory state (where rewriting is not supported). Clear: relates to the logical techniques that help to sanitize data in all user-addressable storage locations for protection against simple non-invasive data recovery techniques.Microsoft uses three categories of data sanitization for DBDs and assets containing data: Any asset retired from service is evaluated for disposal in a manner commensurate with its security/privacy requirements and asset classification, and in accordance with any applicable rules, laws, and regulations. ![]()
