Applications that run on your Mac connect to the Internet to download updates or to send information about a program. For example, when you open Apple iTunes, it connects to the Internet to get the latest Store information of iTunes. If you trust the application, you can allow the application to connect to the Internet.
In some cases, you may want to deny Internet access for some applications. For example, your Norton product notifies you about an application that tries to connect to the Internet. You can block the Internet connection for the application to prevent it from sending or receiving any malicious information.
You can use the Application Blocking window to configure the Internet access for an application. The selected application appears in the Settings list in the Application Blocking window. The application name and the firewall setting that you select appear in the Settings list in the Application Blocking window.
