How do we block synfin port scan.

You can configure zone protection on your outside zone or zone that you are more concerned about.


You can define various action. In above example, I have asked firewall to block source IP for 300 secs if that ip is trying to scan the tcp port. You can customize the alert and threshold as well. Hope this helps. Thank you.

Have you tried the syn flood or TCP port scan in zone protection profile ? Is it not working for synfin port scan ?

I have applied zone protection policy and it is set on alert.

I tried to port scan using nmap. however i could not see any hits using the command show counter global name flow_parse_l4_tcpsynfin.

Is there any way to see the zone protection logs.
