Which DSAC domain deals with encryption and data protection methods?

• A. Network Security
• B. Cryptography
• C. Governance
• D. Software Assurance

Answer: (B)

Cryptography is the discipline that governs how information is transformed to stay confidential and protected, using encryption, decryption, keys, and cryptographic algorithms. The focus is on encryption and data protection methods, including symmetric and asymmetric encryption, hashing, and digital signatures, plus how keys are generated, stored, and managed. This underpins protecting data both at rest and in transit—think encrypted files, secure communications like TLS, and protected databases. Other DSAC domains address related areas (such as securing networks, implementing governance, or building secure software), but encryption and data protection techniques belong to cryptography. That’s why this is the best choice.
