DNS Message Type

DNS Message Type

The following table lists the system and auto rules that are used to mitigate DNS message type attacks on your advanced appliance.

All rules for DNS record types are system rules. By default, they are configured as Pass rules. You can override this and change the rule action to Drop. Note that when you do that, the appliance drops all DNS packets that contain the requested record type. For information about the parameters, see Overview of Packet Flow.
