Which of the following controls BEST helps to maintain the integrity of customer information?

The correct answer is C. Hashing. Hashing is the cryptographic control specifically designed to verify data integrity. A hash function produces a fixed-length digest of data; any alteration to the data - however small - produces a completely different hash, making tampering immediately detectable. This directly a

Explanation

Hashing is the cryptographic control specifically designed to verify data integrity. A hash function produces a fixed-length digest of data; any alteration to the data - however small - produces a completely different hash, making tampering immediately detectable. This directly addresses integrity. Encryption (Option A) addresses confidentiality, not integrity (encrypted data can still be corrupted or replaced). Logging (Option B) creates an audit trail but does not prevent or detect data tampering at the field level. Access control lists (Option D) restrict who can access data but do not verify whether the data itself has been altered. Hashing (e.g., SHA-256) is the standard integrity control.
