___________________ are the most important security measure a company or individual can take.

• A. Encryption
• B. Password
• C. Integrity
• D. Backup

Answer: (D)

Backups are the foundation of recoverability and business continuity. When data is lost or compromised, having recent, verified copies lets you restore systems and information with minimal downtime. Encryption, strong passwords, and integrity checks all protect data, but they don’t automatically recover lost files or return systems to a pre-incident state. Encryption keeps data unreadable to attackers; passwords prevent unauthorized access; integrity checks help detect tampering. Backups change the equation by providing a retrievable copy you can restore from after an incident, including ransomware, hardware failure, or accidental deletion. To maximize effectiveness, follow good backup practices like the 3-2-1 rule (three copies, two different media, one offsite), keep backups offline or air-gapped when possible, and regularly test restores to ensure data can be recovered.
