CISM Certified Information Security Manager – Question0591

Which of the following BEST ensures that information transmitted over the Internet will remain confidential?

A.
Virtual private network (VPN)
B. Firewalls and routers
C. Biometric authentication
D. Two-factor authentication

Correct Answer: A

Explanation:

Explanation: Encryption of data in a virtual private network (VPN) ensures that transmitted information is not readable, even if intercepted. Firewalls and routers protect access to data resources inside the network and do not protect traffic in the public network. Biometric and two-factor authentication, by themselves, would not prevent a message from being intercepted and read.
