the NTP key ID, and the NTP key value. If you do not have those at this time, you can configure
NTP later. Otherwise, you can choose unauthenticated NTP.

filtered out and never sent.
• Full—All data is contributed to the SensorBase Network except the attacker/victim IP addresses that
you exclude.
The SensorBase Network Participation disclaimer appears. It explains what is involved in participating
