threat logs - type vulnerability and spyware - Action - reset both and drop

[MP18]

Under threats logs i see type as :

type  vulnerability   action - reset both-----------sev is high

does this mean that if it is DNS query traffic this will time out the traffic?

Threat ID here is 54122

type  spyware   action is drop --------------sev is drop

as name says it will drop the traffic right?

so if server is doing dns query to dns server how the action reset both and drop works?

@MP18,

"does this mean that if it is DNS query traffic this will time out the traffic?

Threat ID here is 54122" (54122 isn't showing as a valid Vulnerability signature btw)

If the action is reset-both a reset will be sent to both the Source and Destination; essentially the firewall lets the devices know that it's closing the connection. With DNS traffic I'm not positive that will really matter, since the DNS request doesn't get a result it'll probably simply look like the traffic timed-out from the client side of things. 

as name says it will drop the traffic right?

Correct, nothing is sent to the client or the server and the connection is simply dropped on the firewall. 

so if server is doing dns query to dns server how the action reset both and drop works?

Specific to DNS queries I believe that either method will visually look the same. Since the client never gets a valid response it should show that it aged_out without a response from the client side of things.

Can you please explain --

since the DNS request doesn't get a result ?

@MP18,

If the traffic is being reset the DNS request wouldn't recieve a response from the DNS server.
