Abstract

The disclosed apparatus may include a secure storage device that securely stores an initial geographic location of a network device that facilitates network traffic within a network. This apparatus may also include a processing unit communicatively coupled to the secure storage device. The processing unit may determine a current geographic location of the network device. The policy-enforcement unit may then detect evidence of theft of the network device by (1) comparing the current geographic location of the network device with the initial geographic location of the network device and (2) determining, based at least in part on the comparison, that the current geographic location of the network device does not match the initial geographic location of the network device. Finally, the processing unit may perform at least one security action in response to detecting the evidence of theft of the network device.

First claim

What is claimed is:

1. An apparatus comprising:
a secure storage device that securely stores an initial geographic location of a network device that facilitates network traffic within a network; and
a processing unit communicatively coupled to the secure storage device, wherein the processing unit:
determines a current geographic location of the network device that facilitates network traffic within the network;
detects evidence of theft of the network device by:
determining that the network device is experiencing an unexpected power outage;
in response to determining that the network device is experiencing the unexpected power outage, comparing the current geographic location of the network device with the initial geographic location of the network device securely stored in the secure storage device; and
determining, based at least in part on the comparison, that the current geographic location of the network device does not match the initial geographic location of the network device; and

in response to detecting the evidence of theft of the network device, protects the network device from threats of theft by:
utilizing a dying gasp capacitor within the network device to alert an administrator of the network device about both the unexpected power outage and the current geographic location of the network device; and
directing the network device to operate within a restricted mode of operation until determining that the administrator has entered, into the network device, authentication credentials that enable the network device to return to a normal mode of operation.

2. The apparatus of claim 1 , wherein the secure storage device comprises a Trusted Platform Module (TPM) chip.

3. The apparatus of claim 1 , wherein the processing unit determines the current geographic location of the network device using a Global Positioning System (GPS) of the network device.

4. The apparatus of claim 1 , wherein the processing unit further determines the current geographic location of the network device on a periodic basis.

5. The apparatus of claim 1 , wherein the processing unit determines that the current geographic location of the network device is beyond a certain distance from the initial geographic location of the network device.

6. The apparatus of claim 1 , wherein the processing unit directs the network device to operate within the restricted mode of operation by at least one of:
preventing the network device from facilitating network traffic;
preventing any changes from being made to a configuration of the network device; and
preventing access to data stored within the network device.

7. The apparatus of claim 1 , wherein the processing unit further determines the current geographic location of the network device in response to detecting a boot up operation of the network device.

8. The apparatus of claim 7 , wherein the processing unit:
compares the current geographic location of the network device with the initial geographic location of the network device in response to detecting the boot up operation of the network device;
determines, based at least in part on the comparison, that the current geographic location of the network device does not match the initial geographic location of the network device; and
detects additional evidence of theft of the network device based at least in part on the current geographic location not matching the initial geographic location.

9. The apparatus of claim 8 , wherein the processing unit prevents the network device from completing the boot up operation in response to detecting the additional evidence of theft of the network device.

10. The apparatus of claim 9 , wherein:
the secure storage device stores the initial geographic location of the network device within a register accessed during the boot up operation; and
the processing unit prevents the network device from completing the boot up operation by binding the register with the boot up operation such that the boot up operation fails in response to the current geographic location of the network device not matching the initial geographic location stored in the register.

11. A system comprising:
a Trusted Platform Module (TPM) chip that securely stores an initial geographic location of a router that facilitates network traffic within a network; and
a processing unit communicatively coupled to the TPM chip, wherein the processing unit:
determines a current geographic location of the router that facilitates network traffic within the network;
detects evidence of theft of the router by:
determining that the router is experiencing an unexpected power outage;
in response to determining that the router is experiencing the unexpected power outage, comparing the current geographic location of the router with the initial geographic location of the router securely stored in the TPM chip; and
determining, based at least in part on the comparison, that the current geographic location of the router does not match the initial geographic location of the router; and

in response to detecting the evidence of theft of the router, protects the router from threats of theft by:
utilizing a dying gasp capacitor within the router to alert an administrator of the router about both the unexpected power outage and the current geographic location of the router; and
directing the router to operate within a restricted mode of operation until determining that the administrator has entered, into the router, authentication credentials that enable the router to return to normal mode of operation.

12. The system of claim 11 , wherein the processing unit directs the router to operate within the restricted mode of operation by at least one of:
preventing the router from facilitating network traffic;
preventing any changes from being made to a configuration of the router; and
preventing access to data stored within the router.

13. The system of claim 11 , wherein the processing unit further determines the current geographic location of the router in response to detecting a boot up operation of the router.

14. The system of claim 13 , wherein the processing unit:
compares the current geographic location of the router with the initial geographic location of the router in response to detecting the boot up operation of the router;
determines, based at least in part on the comparison, that the current geographic location of the router does not match the initial geographic location of the router; and
detects additional evidence of theft of the router based at least in part on the current geographic location not matching the initial geographic location.

15. The system of claim 14 , wherein the processing unit prevents the router from completing the boot up operation in response to detecting the additional evidence of theft of the router.

16. The system of claim 15 , wherein:
the TPM chip stores the initial geographic location of the router within a register accessed during the boot up operation; and
the processing unit prevents the router from completing the boot up operation by binding the register with the boot up operation such that the boot up operation fails in response to the current geographic location of the router not matching the initial geographic location stored in the register.

17. A method comprising:
determining a current geographic location of a network device;
detecting evidence of theft of the network device by:
determining that the network device is experiencing an unexpected power outage;
in response to determining that the network device is experiencing t
