Which of the following terms ensures that no intentional or unintentional unauthorized modification is made to data?

Non-repudiation ensures that a party cannot deny having performed an action, which is different from preventing data modification itself.

Integrity is the security principle that guarantees data has not been changed or tampered with, thereby maintaining its accuracy and trustworthiness throughout its lifecycle. It ensures that data remains in its original, correct state and has not been subjected to unauthorized modification.

Authentication is the process of verifying a user's identity, not protecting data from modification after identity verification.

Confidentiality protects data from unauthorized disclosure, not from unauthorized modification.
