Explanation / Answer
Data Destruction:
Data destruction is the process of destroying data stored on tapes, hard disks and other forms of electronic media so that it is completely unreadable and cannot be accessed or used for unauthorized purposes.
When data is deleted, it is no longer readily accessible by the operating system or application that created it. But deleting a file is not enough; data destruction software must be used to overwrite the available space/blocks with random data until it is considered irretrievable.
Data destruction categories:
Three major categories of data destruction are 1)Clear,2)purge,3)Destroy
Clear:
A method of sanitization that applies programmatic, softwarebased techniques to sanitize data in all user-addressable storage locations for protection against simple non-invasive data recovery 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).
Purge:
A method of sanitization that applies physical or logical techniques that render Target Data recovery infeasible using state of the art laboratory techniques.
Destroy:
A method of sanitization that 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.
