In addition to collecting host data from monitored network traffic, You can map fingerprints to systems in the vulnerabilityĭatabase (VDB) to allow the appropriate vulnerability information to beĭisplayed whenever a host is identified using the custom fingerprint. If the system cannot identify a host's operating system, you canĬreate custom client or server fingerprints.
