Explanation:
The impact level 4 is used by Cisco FireSIGHT Defense Center to indicate that either the source or target host is on a monitored network but has no corresponding entry in the network map. FireSIGHT uses impact levels to describe the potential severity of attacks. In the FireSIGHT system, managed devices, like Cisco FirePOWER Intrusion Prevention Systems (IPSs), respond to an intrusion event by flagging the event with an impact level and sending the event to the FireSIGHT Defense Center. The impact level is based on accumulated intrusion data, network discovery data, and vulnerability information. The aggregated intrusion event data typically contains contextual information about the event and includes a copy of the packet that triggered the event.
The following table provides a summary of the FireSIGHT impact levels and their meaning:
