ITPEC FE Morning October 2019 Question 37
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.
