Hi all ,

 

I seem to have a lot of  following enteries of this type in my logs 

 

TCP packet out of state: First packet isn't SYN

                        tcp_flags: FIN-ACK

 

I wonder about the security risk of  disabling the option " Drop out of
State Tcp Packets ". I understand that if I disable the option the 

Packet received which is out of state will then just be compared against
the rulebase. I have been advised not to disable it .

I need to understand what risks are there in disabling this feature as
the traffic that we receive is via a network with which sends messages

At different intervals in a day and then we get the above message in the
logs

However I also have a network connected to the internet do I don't wan
to make changes globally that will be a risk.

Please advise
