The embodiment of the present invention discloses a networking control method, device and
system, a security gateway and a mobile terminal, wherein the method comprises the steps of using the security gateway to determine whether to allow a
network connection request to pass according to a preset rule aiming at the
network connection request sent by an application program on the mobile terminal; if not, blocking the
network connection request; if yes, passing the network connection request; acquiring the information of the application programs consuming the network flow in the mobile terminal; querying whether the information of the application programs consuming the network flow is recorded in a pre-generated configuration
list, wherein the application programs operated at the foreground at different time are recorded in the configuration
list; if the information of the application programs consuming the network flow is not recorded in the pre-generated configuration
list, generating and sending out a prompting message whether to forbid the application programs consuming the network flow to connect a network, and when the prompting message of forbidding the application programs consuming the network flow to connect the network is received,
cutting the network connection of the corresponding application program. According to the embodiment of the present invention, the differentiated management of the flow generated by the application programs can be realized.
