To what does logon abuse refer?

A.
Legitimate users accessing networked services that would normally
be restricted to them

B.
Nonbusiness or personal use of the Internet

C.
Intrusions via dial-up or asynchronous external network connections

D.
Breaking into a network primarily from an external source

Explanation:
The correct answer is “Legitimate users accessing networked services that would normally
be restricted to them”. Logon abuse entails an otherwise proper

Answer “Breaking into a network primarily from an external source” is called network intrusion, and
d refers to backdoor
remote access.
