ITPEC FE Morning April 2018 — Question 37 of 80
Information Security (CIA Triad) — Falsification threatens integrity
The CIA triad defines three pillars of information security: Confidentiality, Integrity, and Availability.
Integrity means data has not been altered or tampered with by unauthorized parties.
- •b) Falsification of a web page — modifying content without authorization directly threatens integrity. ✅
Why not the others:
- a) DoS attack — overloads the system, making it unavailable → threatens Availability
- c) Tapping communication content — intercepting data in transit → threatens Confidentiality
- d) Unauthorized copying of data — accessing/duplicating stored data → threatens Confidentiality
Key rule: Integrity = protection against unauthorized modification. If data is changed, forged, or falsified — it's an integrity violation.
