DNS security and cloud lookup


With PAN OS 9.0 Does PA do cloud clookup for everydomain 



only for domains which are not in DNS sinkhole of Antispyware profile?


I was told DNS security is a  part of PAN DB  so when clouds verdict is that particular domain is  bad hows does this info come to PA in real time?


I know it comes via Management interface but which security profile or database it uses to update the PA?

Re: DNS security and cloud lookup


If a DNS query is sinkholed by ThreatPrevention, it will not need to be looked up by DNS Security. 

DNS Security does cloud lookups for every query it sees (unless the result is already cached) pretty much in the same way URL Filtering works. It is applied in the DNS Signatures  section of the AntiSpyware profile, there is no local database, rather a cache is used and cloud lookups are done through the management interface (or a service route)
