Which of the following applet intrusion issues poses the GREATEST risk of disruption to an
organization?

A.
A program that deposits a virus on a client machine

B.
Applets recording keystrokes and, therefore, passwords

C.
Downloaded code that reads files on a client’s hard drive

D.
Applets opening connections from the client machine

Explanation:
An applet is a program downloaded from a web server to the client, usually through a web browser
that provides functionality for database access, interactive web pages and communications with
other users. Applets opening connections from the client machine to other machines on the network
and damaging those machines, as a denial-of-service attack, pose the greatest threat to an
organization and could disrupt business continuity. A program that deposits a virus on a client
machine is referred toas a malicious attack (i.e., specifically meant to cause harm to a client
machine), but may not necessarily result in a disruption of service. Applets that record keystrokes,
and therefore, passwords, and downloaded code that reads files on a client’s hard drive relate more
to organizational privacy issues, and although significant, are less likely to cause a significant
disruption of service.
