New Japanese cybersecurity regulations for vehicles

Japan is also getting ready for legal challenges of cybersecurity in vehicles

The Japanese Ministry of Land, Infrastructure, Transport and Tourism (MLIT) has issued a draft legislation for software updates for motor vehicles in use. The draft describes the conditions under which an original equipment manufacturer (OEM) or an importer can distribute software updates which affect a vehicle type.

To get a permit, before distribution, they should apply for the Conformity of Certificate of Cyber Security Management System (CSMS) and Software Update Management System (SUMS). Requirements for CSMS and SUMS are listed in the draft legislation. Among others, the OEM or importer should prove that their processes to manage cyber security, to identify risks, to test the security, to detect and monitor cyber-attacks, to identify target vehicles for a software update, to assess the impact of a software update, etc. are in place and are adequate.

The major provisions of the legislation are expected to enter into force after January 2022 (for new vehicle types).

The legislation is said to be in line with the new UNECE regulations for cybersecurity and software updates in vehicles. If you want to find out more about them, follow our future insights.
