Which of the following can be used to detect new attacks not previously identified?

A.
Signature-based IDS

B.
Knowledge-based IDS

C.
Behavior-based IDS

D.
Expert system

Explanation:
One of the benefits of behavior-based IDS is that it can detect new
attacks because it is not comparing strings within packets against a static
database. Signature-based IDS cannot detect new attacks that have not been
previously identified.
