The US Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) has released updated guidance to the automotive industry for improving vehicle cybersecurity for safety.

The document, Cybersecurity Best Practices for the Safety of Modern Vehicles, is an update to its 2016 edition.

“As vehicle technology and connectivity develop, cybersecurity needs to be a top priority for every automaker, developer, and operator,” said Dr Steven Cliff, NHTSA’s Administrator.

“NHTSA is committed to the safety of vehicles on our nation’s roads, and these updated best practices will provide the industry with important tools to protect Americans against cybersecurity risks.”

NHTSA routinely assesses cybersecurity risks as well as emerging best practices and has said it will consider future updates to these best practices as motor vehicles, motor vehicle equipment, and their cybersecurity evolve.
