Questão 10 — CompTIA SY0-701 CompTIA Security+ Certification Exam
Which of the following is the best way to sanitize an SSD to prevent the exposure of sensitive data while allowing the drive to be reused?
- A. Secure erasing
- B. Degaussing
- C. Formatting
- D. File wiping
- E. Encrypting
Resposta correta:
A
Explicação
Explanation: Correct answer: A. Secure erasing The best way to sanitize an SSD while allowing it to be reused is cryptographic erasure(also called crypto- erase or encrypted erase). This method: - Uses encryption to make data unreadable by destroying encryption keys rather than overwriting data blocks - Is much faster than traditional overwrite methods on SSDs - Is effective on SSDs because of wear-leveling technology (which makes overwriting unreliable) - Renders data inaccessible without erasing the physical storage blocks Other methods like degaussing (doesn't work on SSDs) or physical destruction (prevents reuse) are less suitable. Cryptographic erasure balances security with the reusability requirement.
