This disclosure describes systems, methods, and devices related to vehicle security enhancement. For example, a vehicle may receive a plurality of data values from an onboard diagnostic system (OBD) of a vehicle, wherein a first data value is received from a first sensor of the vehicle and a second data value is received from a second sensor of the vehicle. The vehicle may determine a third data value received from a controller area network (CAN) bus of the vehicle. The vehicle may determine the third data value is associated with a false message originating from a device external to the vehicle based on performing a correlation analysis between the first value, the second value and the third value. The vehicle may discard the third data value based on the correlation analysis.
