Malicious-DNS

[MEjaz]

Dear bind-users.

 

 

Our NSC, has time to time complaining for such malicious DNS request for few
malicious domains. 

 

Whereas my DNS  servers are up-to-date (BIND 9.12.3-P1)  and only our own
network is allowed to access. 

 

 

 

Complain from NCSA, Nation cyber security Agency. 

 



 

 

 

Up on checking the logs. I found several entries. And you know based on the
below logs I cannot find  the source IP unless I enable the  query logs. If
I enabled the system performs will slow down? Please any ones advice would
be highly appreciated.
