Detection of third-party devices on a vehicle bus

A monitoring device comprising:

• a processor;
• and
• a memory coupled with and readable by the processor and storing therein a set of instructions which, when executed by the processor, causes the processor to:
• listen to electronic messages exchanged on the communications bus, wherein the electronic messages comprise requests for data and responses to the requests for data;
• detect a third-party device communicating on the communications bus based on the electronic messages exchanged on the communication bus;
• monitor the requests for data sent from the third-party device on the communications bus and the responses to the requests sent to the third-party device on the communications bus;
• and
• modify electronic messages sent by the monitoring device on the communications bus based on the monitoring of the requests for data sent from the third-party device on the communications bus and the responses to the requests sent to the third-party device on the communications bus.

A non-transitory, computer-readable medium comprising a set of instructions stored therein which, when executed by a processor, causes the processor to:

• listen to electronic messages exchanged on the communications bus, wherein the electronic messages comprise requests for data and responses to the requests for data;
• detect, a third-party device communicating on the communications bus based on the electronic messages exchanged on the communication bus;
• monitor the requests for data sent from the third-party device on the communications bus and the responses to the requests sent to the third-party device on the communications bus;
• and
• modify electronic messages sent by the monitoring device on the communications bus based on the monitoring of the requests for data sent from the third-party device on the communications bus and the responses to the requests sent to the third-party device on the communications bus.
