Which of the following would BEST protect an organization’s 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.
