Explanation

Integrity ensures that data has not been modified, tampered with, or altered in transit or at rest. Controls such as digital signatures, hashing (e.g., SHA-256), and message authentication codes (MACs) verify that a message arrives exactly as it was sent. While 'not intercepted' maps to Confidentiality, the exam answer focuses on the 'not altered' aspect - the assurance that the message content remains unchanged from sender to recipient. Confidentiality addresses preventing unauthorized viewing, Availability addresses uptime and access, and Safety is not a standard information security pillar. Integrity is the control that guarantees the authenticity and completeness of transmitted data.
