Question 8

The ____ protocol is used for public-key encryption to secure a channel over the Internet.
A) RSA
B) IPSec
C) SSH
D) SSL

Accepted Answer

SSL (Secure Sockets Layer) is a protocol used to secure a channel over the Internet using public-key encryption.

Question 9

Where is information most vulnerable?
A) When it is inside the organization's systems
B) When it is outside the organization's systems
C) When it is being saved on a backup tape inside the organization's systems
