What is the primary goal of the 'integrity' pillar of the CIA triad?
⚠ Common exam trap
Cisco often tests the distinction between integrity and non-repudiation, as candidates may confuse 'proof of action' (non-repudiation) with 'data unchanged' (integrity), leading them to incorrectly select Option C.

Correct answer & explanation
✓
Protect data from unauthorized modification
The 'integrity' pillar of the CIA triad ensures that data is not altered or tampered with by unauthorized parties. This is achieved through mechanisms such as hashing (e.g., SHA-256), checksums, and digital signatures that detect any unauthorized modification. Option D correctly identifies this goal, as protecting data from unauthorized modification is the core purpose of integrity controls.
