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 turning it into ciphertext that looks like random data. Without the decryption key, stored information is unreadable, so even if an adversary gains access to the storage device, they can’t interpret what’s there. This confidentiality aspect is the main benefit in information warfare, helping to keep sensitive material secure even if media is compromised. It doesn’t inherently speed up access to data; decryption adds processing overhead, though systems optimize this for legitimate use. It also doesn’t change the need for data backups or redundancy, though backups themselves can and should be encrypted.
