IOT device risk assessment and scoring
Techniques for establishing a risk score for Internet of Things (IoT) device parameters and acting in response thereto are disclosed. One or more data packets transmitted to or from an Internet of Things (IoT) device are analyzed to obtain event parameters. The event parameters are analyzed to determine a context of the IoT device. A behavior of the IoT device is determined based at least in part on the event parameters and the context. A progressive risk score is obtained for the IoT device. Subsequent to obtaining the progressive risk assessment score, the progressive risk assessment score is updated based at least in part on an analysis of one or more additional data packets.
1. A method, comprising:
analyzing one or more data packets transmitted to or from an Internet of Things (IoT) device over a network to which the IoT device is connected to obtain event parameters;
analyzing the event parameters to determine a context of the IoT device;
determining behavior of the IoT device based at least in part on the event parameters and the context of the IoT device;
obtaining a progressive risk assessment score for the IoT device;
subsequent to obtaining the progressive risk assessment score for the IoT device, updating the progressive risk assessment score based at least in part on analysis of one or more additional data packets; and
sending an alert via the network when it is determined that the progressive risk assessment score exceeds a threshold.
2. The method of claim 1 , wherein the event parameters comprise one or more of data and metadata.
3. The method of claim 1 , further comprising using a network administration engine, including a graphical user interface, to facilitate one or more of providing data to and receiving instructions from an administrator of the network to which the IoT device is connected.
4. The method of claim 1 , wherein a severity of the alert is based on one or more of priorities and rules of an administrator of the network to which the IoT device is connected.
5. The method of claim 1 , wherein the alert is a policy violation alert, a threat alert, or an incident alert.
6. The method of claim 1 , wherein the one or more data packets are correlated to an event of a particular application being executed on the IoT device.
7. The method of claim 1 , wherein the one or more data packets are analyzed using packet header analysis.
8. The method of claim 1 , wherein the one or more data packets are analyzed using deep packet inspection (DPI).
9. The method of claim 1 , further comprising using activity graphs to update the progressive risk assessment score.
10. A system, comprising:
a processor configured to:
analyze one or more data packets transmitted to or from an Internet of Things (IoT) device over a network to which the IoT device is connected to obtain event parameters;

determine behavior of the IoT device based at least in part on the event parameters and the context of the IoT device;
obtain a progressive risk assessment score for the IoT device;
subsequent to obtaining the progressive risk assessment score for the IoT device, update the progressive risk assessment score based at least in part on analysis of one or more additional data packets; and
send an alert via the network when it is determined that the progressive risk assessment score exceeds a threshold; and
a memory coupled to the processor and configured to provide the processor with instructions.
11. The system of claim 10 , wherein the event parameters comprise one or more of data and metadata.
12. The system of claim 10 , wherein the system further includes a network administration engine that includes a graphical user interface to facilitate one or more of providing data to and receiving instructions from an administrator of the network to which the IoT device is connected.
13. The system of claim 10 , wherein a severity of the alert is based on one or more of priorities and rules of an administrator of the network to which the IoT device is connected.
14. The system of claim 10 , wherein the alert is a policy violation alert, a threat alert, or an incident alert.
15. The system of claim 10 , wherein the one or more data packets are correlated to an event of a particular application being executed on the IoT device.
16. The system of claim 10 , wherein the one or more data packets are analyzed using packet header analysis.
17. The system of claim 10 , wherein the one or more data packets are analyzed using deep packet inspection (DPI).
18. The system of claim 10 , wherein the processor is further configured to use activity graphs to update the progressive risk assessment score.
19. The system of claim 10 , wherein at least a portion of the system is implemented remotely from the IoT device.
20. A computer program product embodied on a non-transitory medium, the computer program product including instructions which, when the computer program product is executed by a computer, cause the computer to carry out a method comprising:
