Assignee: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 2:
3. A computing device comprising:
a main processor to run an operating system enabled to reference a main interrupt descriptor table, wherein the main interrupt descriptor table references instructions for execution when an external device is connected to the computing device;
a communication interface to receive a lock signal; and
a communication interface controller to, in response to the communication interface receiving the lock signal, cause the main processor to halt the operating system and to enter a secure operating mode, wherein the secure operating mode is enabled to reference an alternative interrupt descriptor table when the external device is connected to the computing device, wherein the alternative interrupt descriptor table references alternative instructions for execution when the external device is connected to the computing device and wherein the alternative instructions referenced by the alternative interrupt descriptor table includes instructions for the main processor to log indications of attempts of external devices to be connected to the computing device.
