After Outpost detects an attack and displays the "Port Scan Detected" message in the logs, it can be configured to avoid possible future attacks.

Click Settings
Specify the steps Outpost Firewall is to follow if an attack on your computer is detected:
Block all traffic for, if selected, blocks all network exchanges to and from your computer for the specific number of minutes you set (10 minutes is the default).
Block the intruder's IP for, if selected, blocks all network exchanges from the computer attacking yours for the number of minutes you set (60 minutes is the default).
Also block intruder's subnet, if selected, blocks all network exchanges from the entire subnet to which the intruder belongs.
We highly recommend that you do not enable Block all traffic for after a port scanning because disabling regular port scans can result in your inability to work on the Internet after an innocuous port scan.
You can quickly access the plug-in's properties by right clicking on its name in the Left Panel of Outpost Firewall's main window.
