Which of the following is a method to protect data?

• A. Control Access to Physical Data
• B. Use Portable USB Drives Without Authorization
• C. Disable Backups
• D. Require Passwords for Admin Accounts

Answer: (A)

Controlling who can touch the devices that store data is a fundamental way to protect it. If physical access to computers, servers, storage drives, or backups is restricted—using locked rooms, locked cabinets, access logs, and surveillance—you prevent unauthorized people from copying, stealing, or tampering with data. Even the strongest digital protections can be bypassed if someone can physically access the hardware, so physical security serves as a crucial first barrier.

Requiring passwords for admin accounts is important, but it addresses login access rather than direct physical possession of hardware. Using USB drives without authorization invites data leakage, and disabling backups eliminates a critical safeguard for data recovery. So, safeguarding physical access to data storage is the most robust single measure among these options.
