Hi,

I'm wondering about what action (if any) Kerio Control takes on Port Scans. Obviously there's a plethora of benign and malevolent bots and systems which scan IP addresses all around the world looking for open ports.

I've noticed that based on black list severity Control will drop packets and/or block vast amounts of undesirable traffic hitting the firewall.

My question though is specifically about port scans (of which there are between 10 and 50 log entries in a given day). Are the log entries (sample below) purely informational? Does Control take any action on these?

18/Apr/2016 10:15:17] IPS: Port Scan, protocol: UDP, source: 175.41.9.80, destination: xxx.xxx.xxx.xxx, ports: 33434, 33435, 33436, 33437, 33438, 33439, 33440, 33441, 33442, 33443, ...

[18/Apr/2016 10:15:18] IPS: Port Scan, protocol: UDP, source: 203.113.139.6, destination: xxx.xxx.xxx.xxx, ports: 33434, 33435, 33436, 33437, 33438, 33439, 33440, 33441, 33442, 33443, ...

More importantly is there any particular action that should be taken to reduce this activity?

Thanks,
Paul
