Diagnostic Link Connector Security
Published June 2, 2018 by SAE International in United States
This document describes some of the actions that should be taken to help ensure safe vehicle operation in the case that any such connected device (external test equipment, connected data collection device) has been compromised by a source external to the vehicle. In particular, this document describes those actions specifically related to SAE J1979, ISO 15765, and ISO 14229 standardized diagnostic services.
Generally, the following forms of communication bus connection topologies are used in current vehicles:
Open access to communication buses
Communication buses isolated via a gateway
Hybrid combinations of a. and b.
This document contains a set of recommendations to address the issues raised by the 2016 request from the US House of Representatives to NHTSA and the subsequent request from NHTSA to SAE regarding the risk to the modern vehicle ecosystem posed by the SAE J1962 Connector. These recommendations are aimed at all future vehicle applications requiring standardized communication access through this connector.

* Redlines comparisons are available for those standards listed in the Revision History that contain a radio button. A redline comparison of the current version against a revision is accomplished by selecting the radio button next to the standard and then selecting 'compare'. At this time, Redline versions only exist for some AMS standards. SAE will continue to add redline versioning with ongoing updates to SAE MOBILUS.
