Question

which practice is compatible with security principles?

two-factor authentication
secure coding
cryptography
ciphertext

Explanation:

Analyze the question and options

The question asks to identify which option is a "practice" compatible with security principles.

Evaluate each option

• two-factor authentication: This is a specific mechanism or technology rather than a broad development or operational practice.
• secure coding: This is an active development practice of writing software that is guarded against security vulnerabilities.
• cryptography: This is a field of study or a mathematical discipline, not a practice itself.
• ciphertext: This is a noun referring to encrypted data, not a practice.

Select the best fit

"Secure coding" is the only option that represents a systematic development practice aligned with security principles.

Answer:

• two-factor authentication
• secure coding (Correct answer)
• cryptography
• ciphertext
