address.
Rule
With a mouse click on the link you have the choice to add or not to add the rule to
block the TCP port scan attack.
UDP port scan
With this rule, you can define when a UDP port scan is assumed by the FireWall and what
should be done in this case. This rule prevents so-called UDP port scan attacks that result
in a detection of open UDP ports on your computer. This kind of attack is used to search a
computer for weak spots and is often followed by more dangerous attack types.
