Certificate of Cloud Auditing Knowledge (CCAK) — Question 23

Which of the following data destruction methods is the MOST effective and efficient?

Answer options

• A. Crypto-shredding
• B. Degaussing
• C. Multi-pass wipes
• D. Physical destruction

Correct answer: A

Explanation

Crypto-shredding is considered the most effective and efficient method because it encrypts data before deletion, ensuring that the data cannot be recovered even if the storage media is accessed. Degaussing, multi-pass wipes, and physical destruction are effective but may not guarantee complete data irretrievability or can be more time-consuming compared to crypto-shredding.
