Abstract
A connected vehicle has several electronic control units (ECUs). Entities running in different ECUs are constrained in corresponding security boundaries. Messages across security boundaries are transmitted over a connection that is not directly available to entities constrained in security boundaries. Messages across security boundaries between entities are inspected. A message from an entity in one security boundary to another entity in another security boundary is inspected by normalizing a content of the message, and comparing the normalized content to a baseline. A corrective action is performed against the message in response to determining that a difference between the normalized content and the baseline indicates a change that is prohibited by a security policy.
