Specified application rules in the extended configuration
Specified application rules allow you to allow or deny specified data traffic for the
application or allow or deny passive listening to individual ports. The following options
are available:
Allow or deny code injection
Code injection is a technique for introducing code into the address space of another
process to execute actions, forcing this process to load a dynamic link library (DLL).
Code injection is used by malware, amongst other things, to execute code under
cover of another program. In this way, access to the Internet in front of the Firewall
can be hidden. In default mode, code injection is enabled for all signed applications.
Allow or deny passive listening to the application of ports
Allow or deny data traffic
Allow or deny incoming and/or outgoing IP packets
Allow or deny incoming and/or outgoing TCP packets
Allow or deny incoming and/or outgoing UDP packets
You can create as many application rules as you like for each application. The application
rules are executed in the sequence shown .
Note
If you change the Advanced filtering of an application rule, the already existing
application rules in the extended configuration are simply deactivated, not irretrievably
deleted. If you select Advanced filtering again, the already existing application rules will
be reactivated and displayed in the extended configuration for application rules window.
