Which of the following approaches would NOT be considered sufficient to meet the requirements of secure data destruction within a cloud environment?
Answer options:
A. Cryptographic erasure
B. Zeroing
C. Overwriting
D. Deletion
Answer correct:
D
Deletion merely removes the pointers to data on a system; it does nothing to actually remove and sanitize the data. As such, the data remains in a recoverable state, and more secure methods are needed to ensure it has been destroyed and is not recoverable by another party.
