ITPEC FE Morning October 2021 — Question 36 of 80
Integrity (ISO/IEC 27000) — guarantee that data received equals data sent.
The CIA triad defines three core security properties:
- •Confidentiality — only authorized parties can access the data
- •Integrity — data is not altered during storage or transmission
- •Availability — data and systems are accessible when needed
Non-repudiation is an additional property: the sender cannot deny having sent the message.
Key rule: "data received = data sent" → Integrity.
