Certified Cloud Security Professional (CCSP) — Question 164

Your company is in the planning stages of moving applications that have large data sets to a cloud environment.
What strategy for data removal would be the MOST appropriate for you to recommend if costs and speed are primary considerations?

Answer options

• A. Shredding
• B. Media destruction
• C. Crypthographic erasure
• D. Overwriting

Correct answer: C

Explanation

Cryptographic erasure is effective for securely deleting data while ensuring quick processing and lower costs, making it ideal for cloud environments. In contrast, shredding and media destruction involve physical processes that can be slower and more costly. Overwriting, while effective, may not be as efficient as cryptographic erasure in terms of speed and cost-effectiveness.
