Explanation

Cryptography is the technique of transforming (encrypting) messages into an unreadable format so that only authorized parties can decrypt and read them, directly addressing message security, confidentiality, and protection against interception during Internet communications.

Why the distractors are wrong:

A. Risk analysis identifies and evaluates threats but does not modify or protect messages in transit.
B. OODA loop (Observe, Orient, Decide, Act) is a decision-making framework from military strategy, unrelated to message security.
D. Firewall security controls network traffic at the perimeter but does not encrypt or transform message content itself.

Memory tip: Think "Crypto = Code" - cryptography literally encodes your messages, making it the only option that actively modifies data to secure it during transmission.
