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.
