ISC2 CC Practice Question: Wants to ensure that data remains unaltered…
An organization wants to ensure that data remains unaltered during transmission over the internet. Which security goal is being addressed?
⚠ Common exam trap
ISC2 often tests the distinction between confidentiality and integrity by presenting a scenario about data alteration, where candidates mistakenly choose confidentiality because they associate encryption with all security, ignoring that encryption alone does not prevent tampering.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Integrity
Integrity ensures that data is not altered during transmission, typically verified through cryptographic hash functions (e.g., SHA-256) or message authentication codes (MACs) such as HMAC. Protocols like TLS use integrity checks to detect any unauthorized modification of packets in transit, directly addressing the requirement that data remains unaltered.
