Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.

Non-repudiation
Why it's wrong here
Non-repudiation is not part of the CIA triad; it ensures a party cannot deny an action.
- ✓
Confidentiality
Why this is correct
Confidentiality prevents unauthorized disclosure; reading encrypted traffic without authorization breaches this.

Why it's wrong here
Integrity ensures data is unaltered; reading does not modify data.
