In reading up on DNS Security I found that URL's provided for testing in the following document, Enabling DNS Security, do not accurately ensure DNS Security feature license is installed and configured. A very accurate indicator of this is that all of those URL's are adequately blocked on a firewall running PAN-OS 8.1.x due to the PAN-DB URL filtering policies most companies would have enabled.
Here is the suggested testing method from the above URL:
So this leads me to the questions...
BTW, @PANW - Why is the Oilrig signature default action "alert" instead of blocking it? Using a strict profile is pretty essential.
If you have a successful test plan for DNS Security implementation please comment.
Solved! Go to Solution.
The steps provided were to show you that the DNS Sinkhole functionality was being actioned/"hit on".
While I agree that these same sites are probably used in the Content Profile for URL Categorization, testing was done to provide confirmation that DNS sinkhole was working.
I enabled the Spyware profile to use the licensed DNS security feature.
But, instead of using the default sinkhole.paloaltonetworks.com FQDN, I used a bogus 220.127.116.11 as my sinkhole.
Then I tested the 4 sites.
My traffic was blocked, not because of the URL. In looking at the threat logs, I see the action of sinkhole against the IP of my device.
For confirmation, I filtered on the Traffic log, and saw 4 hits on a destination IP of 18.104.22.168, which were not there, prior to my testing.
Therefore, the DNS Security feature, along with sinkholing to a different IP, shows/provides me confidence that the DNS security feature worked, before the URL filtering profile (which may well have those 4 sites listed), but Spyware profile is what was triggered.
