How does encryption contribute to protecting sensitive data in information warfare?

• A. It increases the speed of data transmission
• B. It allows for public access to confidential information
• C. It protects sensitive data from unauthorized access
• D. It makes data easier to corrupt

Answer: (C)

Encryption protects sensitive data by preserving its confidentiality: it transforms readable information into ciphertext so only someone with the correct key can restore it. In information warfare, this means that even if data is intercepted or accessed by an adversary, the content remains unreadable without the decryption key. This directly limits unauthorized access and helps secure data both in transit and at rest. While encryption can be paired with integrity checks to guard against tampering, on its own it focuses on privacy rather than speed, granting public access, or making data easier to corrupt.
