AUTOMATIC SECURITY ACTION INVOCATION FOR MOBILE COMMUNICATIONS DEVICE
First Claim
1. A server for providing security on at least one mobile communications device, the server being configured to communicate with a plurality of mobile communications devices over a wireless network, the server comprising:
- a processor;
a communications subsystem connected to the processor for exchanging signals with the wireless network and with the processor; and
a security module for sending policy messages to one or more of the devices in the plurality of mobile communications devices at intervals, the policy messages including instructions for execution by the one or more of the devices to enforce or terminate a data protection policy, the policy messages to enforce a data protection policy comprising instructions for execution by the one or more of the devices to perform a security action comprising erasing or encrypting at least some of the data on a storage element if a subsequent policy message to enforce a data protection policy is not received within a duration from the time at which a previous policy message is received.

Abstract
In one embodiment, there is provided a mobile communications device comprising: a processor; a communications subsystem operable to exchange signals with a wireless network; a storage element having application modules and data stored thereon, the data comprising at least user application data associated with the application modules and service data including data for establishing communications with the wireless network; and a security module operable to detect policy messages received by the device, and to perform a security action if a first policy message to enforce a first data protection policy is received and a subsequent policy message to enforce a second data protection policy is not received within a predetermined duration from the time at which the first policy message is received; wherein the security action comprises erasing or encrypting at least some of the data on the storage element.

17. A method for providing security on at least one mobile communications device, the method comprising:
-
generating policy messages including instructions for execution by the one or more of the devices to enforce or terminate a data protection policy, the policy messages to enforce a data protection policy comprising instructions for execution by the one or more of the devices to perform a security action comprising erasing or encrypting at least some of the data on a storage element if a subsequent policy message to enforce a data protection policy is not received within a duration from the time at which a previous policy message is received; and sending the policy messages from a server over a wireless network to one or more of the devices in the plurality of mobile communications devices at intervals. - View Dependent Claims (18, 19, 20, 21, 22, 24)

25. A computer-readable medium having computer-readable instructions stored thereon that when executed cause a processor to execute a method, the method comprising:
-
generating policy messages including instructions for execution by the one or more of the devices to enforce or terminate a data protection policy, the policy messages to enforce a data protection policy comprising instructions for execution by the one or more of the devices to perform a security action comprising erasing or encrypting at least some of the data on a storage element if a subsequent policy message to enforce a data protection policy is not received within a duration from the time at which a previous policy message is received; and sending the policy messages from a server over a wireless network to one or more of the devices in the plurality of mobile communications devices at intervals.
