Which combination of controls helps ensure data integrity in AVN C3 RC?

Which combination of controls helps ensure data integrity in AVN C3 RC?

• A. Checksums alone guarantee unaltered data.
• B. Encryption, checksums, and authentication help ensure data integrity.
• C. Only physical security prevents data tampering.
• D. Data integrity is not important in RC.

Answer: (B)

Maintaining data integrity in AVN C3 RC requires layers that detect tampering, verify origin, and ensure the data hasn’t been altered. Checksums can catch accidental changes but aren’t foolproof against deliberate tampering and don’t prove who created the data. Encryption protects the content and, when paired with authentication, helps ensure that any changes are detected and that the data came from a trusted source. Authentication mechanisms (like MACs or digital signatures) provide proof of origin and integrity. Using encryption, checksums, and authentication together creates a robust, layered approach: checksums detect errors, authentication confirms integrity and origin, and encryption protects data in transit or at rest from being read or subtly modified. Relying solely on physical security isn’t enough, and data integrity is essential in RC operations.
