Define 'data integrity' in AVN C3 RC and name three controls used to protect it.

• A. Backups, version control, and logging.
• B. Encryption, checksums, authentication.
• C. Air gap, air picture, and ISR feeds.
• D. Two-factor verification, firewall, and malware scanning.

Answer: (B)

Data integrity means keeping information accurate and unaltered from its source to its use, with any changes detectable and authorized. In AVN C3 RC environments, protecting this integrity is crucial for trustworthy intelligence and operations. The best trio of controls for this is encryption, checksums, and authentication. Checksums (or hashes) let you detect changes to data by comparing a computed value before and after transmission or storage. Authentication verifies that the data came from a trusted source and hasn’t been replaced by an imposter, helping to prevent tampering. Encryption, especially when implemented as authenticated encryption, provides confidentiality and, when combined with proper integrity checks, helps detect any unauthorized alterations during decryption or verification. Together, these three form a layered approach: you can detect changes, verify origin, and, if using the right encryption mode, ensure that tampering is detectable. The other options focus more on recoverability, operational security, or perimeter protection and do not directly address verifying that data remains correct and unmodified in transit or at rest.
