In the context of information warfare, how does encryption affect data storage?

• A. It renders data unreadable without a decryption key
• B. It allows faster access to stored data
• C. It improves data redundancy
• D. It eliminates the need for data backups

Answer: (A)

Encryption protects data at rest by transforming it into ciphertext that cannot be understood without the correct decryption key. In storage scenarios, this means files, databases, or backups stay confidential even if the storage media is stolen or accessed by an unauthorized actor. The security hinges on keeping the decryption keys safe and properly managed. Encryption does not inherently speed up data access, nor does it improve redundancy or remove the need for backups.
