SI-4(1)

Requirement

Connect and configure individual intrusion detection tools into a system-wide intrusion detection system.

Discussion

Linking individual intrusion detection tools into a system-wide intrusion detection system provides additional coverage and effective detection capabilities. The information contained in one intrusion detection tool can be shared widely across the organization, making the system-wide detection capability more robust and powerful.
