Which policy is used to capture host information on the Cisco Next Generation Intrusion Prevention System?

The network discovery policy on a Cisco Next Generation Intrusion Prevention System (NGIPS) is used to capture detailed information about hosts, operating systems, applications, and services active on the network by passively monitoring traffic to build a comprehensive network map.

Correlation policies are used to link multiple security events across devices or time to identify more complex attacks, not to capture host inventory.

Intrusion policies define how the system detects and prevents intrusions using signatures and other detection methods.

Access control policies determine which network traffic is allowed or blocked based on various criteria like source, destination, application, or user.
