The dialog also allows the user to restrict the parameters of the connection, restricting it to a specific port, protocol, or domain. For that, a dialog is presented to the user, which allows one to deny or permit the connection on a one-time, time limited, or permanent basis. If an application or process attempts to establish a network connection, Little Snitch prevents the connection, if a rule for that connection has been set by the user. Little Snitch controls network traffic by registering kernel extensions through the standard application programming interface (API) provided by Apple.
