Which of the following would BEST protect an organizations confidential data stored on a laptop computer from unauthorized access?

A. Strong authentication by password

B. Encrypted hard drives

C. Multifactor authentication procedures

D. Network-based data backup

Explanation:

Encryption of the hard disks will prevent unauthorized access to the laptop even when the laptop is lost or stolen. Strong authentication by password can be bypassed by a determined hacker. Multifactor authentication can be bypassed by removal of the hard drive and insertion into another laptop. Network- based data backups do not prevent access but rather recovery from data loss.
