Zeke is responsible for sanitizing a set of solid state drives removed from servers in his organization’s data center. The drives will be reused on a different project.
Which one of the following sanitization techniques would be most effective?
A. Cryptographic Erasure
B. Physical Destruction
C. Degaussing
D. Overwriting
Correct Answer: A
Cryptographic erasure is a strong sanitization technique that involves encrypting the data with a strong encryption engine and then taking the keys generated in that process, encrypting them with a different encryption engine, and destroying the resulting keys of the second round of encryption. This technique is effective on both magnetic and solid state drives. Degaussing and overwriting are not effective on SSDs. Physical destruction would effectively sanitize the media but would prevent Zeke from reusing the drives.
