What are the three areas of transmission security?

• A. Interception, Analysis, Deception
• B. Encryption, Authentication, Non-repudiation
• C. Confidentiality, Integrity, Availability
• D. Access, Control, Audit

Answer: (A)

Transmission security focuses on protecting signals as they travel by addressing three distinct risks an observer might pose: interception, analysis, and deception. Interception is about preventing or hindering someone from listening in on the transmission, so measures reduce eavesdropping. Analysis targets what can be learned from the signal itself—timing, frequency usage, traffic patterns—so countermeasures obscure or distort those inferences. Deception involves misleading the observer about the real state or content of the communication, using decoys, false signals, or other tricks to confuse or mislead. Together these cover the main ways an adversary could gain value from a transmission and the primary defensive approaches beyond just encrypting content. The other options describe general security concepts (like encryption and authentication or the CIA triad) that are important but not the three areas specific to transmission security.
