Firewall Preferences

In the Firewall preferences section, you can specify parameters for scanning incoming and outgoing traffic and configure rules for specific applications to access internet resources.

Firewall allows access to network resources for all trusted applications. If application is not on the trusted list, Dr.Web displays a notification and asks which action to take.

ic_arrow90deg Which applications are trusted by Dr.Web?

Among trusted applications are macOS system applications, applications with a security certificate or a valid digital signature. Rules for such applications are not displayed in the filtering list.

You can change Firewall operation mode and create filtering rules for specific applications that do not apply to the selected operation mode.

Operation mode

Select one of the following operation modes:

•Allow Trusted Applications—access to network resources for all trusted applications is allowed. For other applications, Dr.Web displays a notification and asks which action to take.

•Allow All Connections—access to network resources for all unknown applications is allowed. Known connections are processed by Firewall according to specified filtering rules.

•Block All Connections—access to network resources for all unknown applications is blocked. Known connections are processed by Firewall according to specified filtering rules.
