Guarding against improper information modification or destruction, and includes ensuring information non- repudiation and authenticity. Response:

Integrity ensures that information remains accurate, complete, and uncorrupted throughout its entire lifecycle, preventing unauthorized modification or destruction. It also encompasses non-repudiation, which confirms the origin of data or actions, and authenticity, which verifies that data is genuine and has not been tampered with.

Authenticity is a component of integrity, but integrity is the broader concept encompassing protection against modification and destruction, along with non-repudiation.

Confidentiality focuses on preventing unauthorized disclosure of information, not its modification or destruction.

Availability ensures that authorized users have timely and reliable access to information and systems, not protection against modification or destruction.
