ITPEC FE Morning October 2019 — Question 41 of 80
ISO/IEC 27000 Security Properties — identify the definition of authenticity.
In ISO/IEC 27000:2018, authenticity is defined as the "property that an entity is what it claims to be." It confirms that a user, system, or piece of data is genuine.
Why not others:
- (a) Accountability — the property that actions of an entity can be traced uniquely to that entity
- (c) Nonrepudiation — the ability to prove that an action or event took place, so it cannot be denied later
- (d) Reliability — the property of consistent intended behavior and results
Key rule: Authenticity = "you are who you say you are"; Nonrepudiation = "you can't deny what you did."
