Understanding Top Attackers Report

L1 Bithead



The Top Attackers reports lists:

  • Source Address
  • Source Host Name
  • Source User
  • Count

In a report I ran, all of our source addresses are internal addresses.  Why is that?  Is the report more of a top talkers report than an attackers report?  In other words, is the report more of a list high activity accounts or addresses? 


Is the Count the number of sessions the source address has had?






Check ACC > Threat Activity


Most likely top threats are "Suspicious TLS Evasion Found" and "Suspicious HTTP Evasion Found"

If your firewall is not set up as DNS proxy then it does not know if HTTP/SSL requests done by internal devices are going to valid IPs or someone is trying to spoof traffic to get through firewall URL filtering.

So those attempts count against your internal users as attackers.

Thanks!  Appreciate the reply!  So the title of the predefined report is misleading.

Okay.  Thanks for the explanation, Raido!

Greetings! Is there a way to exclude vulnerability scanners or certain IP's from the Panorama "Top Attacker Sources" report section?
