D. All of the mentioned

What are the drawbacks of the host based IDS?

A. Unselective logging of messages may increase the audit burdens
B. Selective logging runs the risk of missed attacks
C. They are very fast to detect
D. They have to be programmed for new patterns

What are the strengths of the host based IDS?
