Abstract:
1. A method comprising steps of: (a) monitoring, by a mobile terminal having a communication link with a circuit switched network, activities performed at the mobile terminal according to a security policy which is enforced by execution of security agent software provided from the circuit switched network via the communication link between the mobile terminal and the circuit switched network, wherein the security policy resides in the mobile terminal and is enforced by the mobile terminal; (b) communicating detection of a suspicious activity defined by the security policy from the mobile terminal to a policy manager server of the circuit switched network when the suspicious activity is detected; (c) changing the security policy, for the mobile terminal in response to the detection of the suspicious activity communicated from the mobile terminal, to cure the suspicious activity detected at the mobile terminal by the policy manager server of the circuit switched network; (d) sending the changed security policy to the mobile terminal via the communication link between the mobile terminal and the circuit switched network such that the mobile terminal is able to receive and use the changed security policy to cure the suspicious activity; and (e) filtering out call traffic including SMS or MMS messages sent from/to be delivered to the mobile terminal relating to the suspicious activity, by an SMSC filter of the circuit switched network, according to the changed security policy.
