Settings for Applications

Firewall allows you to create no more than one set of rules per each application.

Application level filtering helps you to control access of various applications and processes to network resources as well as enable or disable applications to run other processes. You can create rules for both system and user applications.

If the file of an application for which the rule had been created was changed (for example, an update was installed), Firewall prompts to confirm that the application is still allowed to access network resources.

This page lists all applications and processes for which you can modify application filter rule sets by creating new rules, editing existing ones, or deleting those that are no longer needed. Each application is explicitly identified by the path to its executable file. Firewall uses the SYSTEM name to indicate the rule set applied to the operating system kernel (the system process for which there is no unique executable file).

If you created a blocking rule for a process or set Block unknown connections mode and then disabled the rule or changed the work mode, the process will be blocked till its next attempt to establish connection.

When an application is deleted from your computer, the related rules are not automatically deleted. You can delete them manually by clicking Remove unused rules in the shortcut menu of the list.
