What results from all measures designed to protect transmissions from intercept and exploitation by means other than cryptoanalysis?

• A. Transmission Security
• B. Crypto Security
• C. Emission Security
• D. Operational Security

Answer: (A)

Transmission Security focuses on protecting the transmission itself from being intercepted or exploited by means other than breaking the cryptography. It covers measures that make the signal harder to detect, intercept, jam, or analyze without decrypting it—things like spread-spectrum or frequency-hopping techniques, timing and traffic-pattern concealment, and shielding to reduce emissions. This is different from Crypto Security, which protects the message content with encryption and keys, and from Emission Security, which guards against unintended emanations from equipment. Since the question targets safeguarding transmissions through non-cryptanalytic means, Transmission Security is the best fit.
