When installing an intrusion detection system (IDS), which of the following is MOST important?

A.
Properly locating it in the network architecture

B.
Preventing denial-of-service (DoS) attacks

C.
Identifying messages that need to be quarantined

D.
Minimizing the rejection errors

Explanation:
Proper location of an intrusion detection system (IDS) in the network is the most important decision during installation. A poorly located IDS could leave key areas of the network unprotected. Choices B, C and D are concerns during the configuration of an IDS, but if the IDS is not placed correctly, none of them would be adequately addressed.
