Manipulating inter-chip communications for IoT security
Inter-chip communication data in an Internet-of-Things (IoT) device is manipulated and analyzed to identify and remediate security vulnerabilities. Inter-chip communication data in the IoT device is captured. Communication direction, address format, flow control, communication timing, and communication structure associated with the inter-chip communication data is identified. Based on the foregoing identification(s), portions of the inter-chip communication data that require modification are identified so that that inter-chip communication data can be replayed. Based on the modification and the replaying, security vulnerabilities in the IoT device are identified and remediated.
1. A computer-implemented method, comprising:
capturing inter-chip communication data in an Internet of Things (IoT) device;
identifying a communication direction, an address format, a flow control, a communication timing, and a communication structure associated with the inter-chip communication;
based on the communication direction, the address format, the flow control, the communication timing, and the communication structure, identifying one or more portions of the inter-chip communication data that require modification so that the inter-chip communication data can be replayed;
identifying one or more security vulnerabilities based on the modification and the replaying; and
remediating the one or more security vulnerabilities in the IoT device.
2. The computer-implemented method of claim 1 , further comprising:
serializing the captured inter-chip communication data to a file system associated with the IoT device.
3. The computer-implemented method of claim 1 , wherein
the data communication structure comprises a data transmission unit start delimiter, a data transmission unit end delimiter, and at least a length pattern.
4. The computer-implemented method of claim 1 , wherein
the one or more portions of the inter-chip communication data are identified for modification based on data pattern recognition, and
the one or more portions of the inter-chip communication data are modified based on one or more sets of replacement patterns.
5. The computer-implemented method of claim 1 , wherein
the IoT device is communicatively coupled to a breakout board.
6. A non-transitory computer readable storage medium comprising program instructions executable to:
capture inter-chip communication data in an Internet of Things (IoT) device;
identify a communication direction, an address format, a flow control, a communication timing, and a communication structure associated with the inter-chip communication;
based on the communication direction, the address format, the flow control, the communication timing, and the communication structure, identify one or more portions of the inter-chip communication data that require modification so that the inter-chip communication data can be replayed;
identify one or more security vulnerabilities based on the modification and the replaying; and
remediate the one or more security vulnerabilities in the IoT device.
7. A system comprising:
one or more processors; and
a memory coupled to the one or more processors, wherein the memory stores program instructions executable by the one or more processors to:
capture inter-chip communication data in an Internet of Things (IoT) device;
identify a communication direction, an address format, a flow control, a communication timing, and a communication structure associated with the inter-chip communication;
based on the communication direction, the address format, the flow control, the communication timing, and the communication structure, identify one or more portions of the inter-chip communication data that require modification so that the inter-chip communication data can be replayed;
identify one or more security vulnerabilities based on the modification and the replaying; and
remediate the one or more security vulnerabilities in the IoT device.
