siru - i believe this depends on what version of ASM you have. If i recall DNS DoS protection was part of Protocol Security Manager, which then went end of sale and was integrated into ASM. You would need to create a DoS Profile and enabled DNS security. This would be applied to a Virtual Server. I think from 11.4.x this functionality was moved to F5's Advanced Firewall Manager instead, again same process.

 

Hope this helps - and hope and DNS experts could correct me if incorrect.

 

Many thanks,
