The disclosure is of a device and a method of securing machinery supporting controller area network protocol from diagnostics based attacks, by enforcing a diagnostic policy mapping diagnostics requests and their sub-function to associated vehicle states, for example by using a table of diagnostic function identifiers and associated valid vehicle states. When a diagnostic request and Sub-Function are marked valid for the vehicle state, the diagnostic operation is valid. When a diagnostic request and Sub-Function are marked not valid for the vehicle state, the diagnostic operation is not valid, and aborted.
