Abstract: A system for providing privileged access to an internal vehicle communication network is provided. The system includes a presentation network bus configured to provide listen-only access to a subset of in-vehicle networks, a security system configured to enable access to the presentation network bus by verifying access credentials, and a diagnostic service system configured to control access to the presentation network bus. The diagnostic service system is configured to receive a diagnostic service request after the access credentials have been verified to enable the presentation network busses for listen-only access to the subset of the in-vehicle networks. The presentation network busses may be enabled for the listen-only access after credential verification by the security system and in response to receipt of a diagnostic service request from the diagnostic service system requesting that the presentation network busses be enabled.

Abstract: A communication network implements a Universal Measurement and Calibration Protocol (XCP) policy. The communication network includes a plurality of nodes, each of the nodes being operably connected to a bus to send and to receive data communications to and from others of the plurality of nodes. Certain of the data communications include a Universal Measurement and Calibration Protocol (XCP) identifier indicating the presence of XCP protocol within the data frame. At least one of the nodes is configured to mitigate identified XCP protocol in accordance with the policy.
