Abstract

A system and method for analyzing a device are disclosed. In an aspect, a method can comprise determining a parameter of a device at a kernel level of a software stack associated with the device, analyzing the parameter to determine an event state, comparing the event state to a white list to determine a state of an alert trigger, and generating an alert in response to the determined state of the alert trigger.

Claims (43)

1. A method comprising:

receiving a parameter of a device at a kernel level of a software stack associated with the device, wherein the parameter comprises a pattern of operation;

analyzing the parameter at the kernel level of the software stack to determine an event state;

comparing the event state to a white list to determine a state of an alert trigger, wherein the white list comprises acceptable patterns of operation, wherein the acceptable patterns of operation comprise physical patterns;

generating an alert in response to the determined state of the alert trigger;

transmitting the alert to a review device for analysis and determination of a response;

receiving the response from the review device, wherein remediation measures to address the event state are not taken until the response from the reviewer device is received; and

causing, in response to the received response from the review device, implementation of the remediation measures to address the event state.

2. The method of claim 1 , wherein the device is configured to receive signals from a content distribution system.

3. The method of claim 1 , wherein the parameter relates to a physical characteristic of the device.

4. The method of claim 1 , wherein receiving the parameter of the device comprises receiving an indication of a change to an operational process of the device.

5. The method of claim 1 , wherein the pattern of operation comprises a pattern of physical events.

6. The method of claim 1 , wherein the parameter comprises a change in a pattern of physical events.

7. The method of claim 1 , wherein the remediation measures comprise changing services provided to the device.

8. The method of claim 7 , wherein the remediation measures comprise suspending service to the device.

9. A method comprising:

determining a plurality of parameters of a device;

detecting a change in one or more of the plurality of parameters of the device;

defining, based upon one or more of the plurality of parameters and the detected change in the one or more of the plurality of parameters, a pattern of operation of the device;

comparing the pattern of operation of the device to a comparator pattern to determine an event state;

comparing the event state to a white list to determine a state of an alert trigger, wherein the white list comprises acceptable patterns of operation, wherein the acceptable patterns of operation comprise physical patterns;

generating an alert in response to the determined state of the alert trigger;

transmitting the alert to a remote device for analysis and determination of a response;

receiving the response from the remote device, wherein remediation measures to address the event state are not taken until the response from the remote device is received; and

causing, in response to the received response from the remote device, implementation of the remediation measures to address the event state.

10. The method of claim 9 , wherein the device is configured to receive signals from a content distribution system.

11. The method of claim 9 , wherein one or more of the plurality of parameters relates to a physical characteristic of the device.

12. The method of claim 11 , wherein one or more of the plurality of parameters relates to a physical characteristic of the device.

13. The method of claim 9 , wherein the remediation measures comprise changing services provided to the device.

14. The method of claim 13 , wherein the remediation measures comprise suspending service to the device.

15. A method comprising:

determining a parameter of a device using a detection element embedded in a software stack associated with the device, wherein the parameter comprises a pattern of operation;

analyzing the parameter using the detection element to determine an event;

comparing the event to a white list, wherein the white list comprises acceptable patterns of operation, wherein the acceptable patterns of operation comprise physical patterns;

generating an alert based upon comparing the event to a white list, wherein the alert is generated if the white list does not comprise the event;

transmitting the alert to a remote device for analysis and determination of a response;

receiving the response from the remote device, wherein remediation measures to address the event are not taken until the response from the remote device is received; and

causing, in response to the received response from the remote device, implementation of the remediation measures to address the event state.

16. The method of claim 15 , wherein the parameter relates to a physical characteristic of the device.

17. The method of claim 15 , wherein determining a parameter of the device comprises detecting a change to an internal process of the device.

18. The method of claim 15 , wherein the parameter comprises a pattern of physical events.

19. The method of claim 15 , wherein the parameter comprises a change in a pattern of physical events.

20. The method of claim 15 , wherein the remediation measures comprise changing services provided to the device.
