ITPEC FE Morning October 2019 — Question 37 of 80

CIA Triad — Integrity — identify which attack threatens data integrity.

The CIA triad defines three pillars of information security:
- Confidentiality — preventing unauthorized access to information

- Integrity — preventing unauthorized modification or falsification of information

- Availability — ensuring systems remain accessible when needed

Answer: b) Falsification of a web page

Falsifying (altering) a web page means the content has been tampered with — a direct threat to integrity.

Why not others:
- (a) DoS attack — overloads the system, making it unavailable → threatens availability

- (c) Tapping of communication — intercepting data in transit → threatens confidentiality

- (d) Unauthorized copying — accessing data without permission → threatens confidentiality

Key rule: Integrity = data is accurate and unaltered. Any attack that modifies or forges data is an integrity threat.
