Suspicious DNS Query's

obor — Thu, 01 Aug 2013 10:37:38 GMT

Hello,

We are running version 5.0.6 for a few weeks now and looks very good.

We see now also in our threat detection the following threat "Suspicious DNS Query : ......" and this is blocked.

This is very cool to block at dns level spyware and malware but the disadvantage of this is that the source client ip address is always your DNS server.

So you need to look in to your logs of your DNS Server to find out the infected client.

But if you have a distributed DNS infrastructure and many DNS Servers spread over several location in Europe then this a hard job to do.

Why is it not possible to redirect Suspicious DNS Query's to a honeypot IP address so you can then detect the real client's ip address?

Maybe a future request!!

Or does someone have a better idea how to deal with this issue?

maFor us monitoring all the DNS servers log is not a option because we have so many DNS Servers spread over many locations.

Regards,

O. Bor
