The component of communications security that results from the provision of technically sound cryptosystems and their proper use is known as what?

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

Answer: (A)

This question tests how protections in communications security are built from the cryptographic foundations. Crypto security is about protecting information through sound cryptographic algorithms and their proper use—things like strong encryption, correct key management, authentication, and integrity checks. When cryptosystems are well-designed and implemented, and keys are handled correctly, the confidentiality and authenticity of communications are preserved, which is exactly what this component aims to achieve. Transmission security, by contrast, focuses on protecting the data as it travels the channel, often through channel-level protections, while operational security deals with policies, procedures, and human factors, and physical security covers safeguarding hardware and facilities. The description given—technically sound cryptosystems and their proper use—fits cryptographic protections most directly.
