METI Releases Guidelines for Cyber-Physical Security Measures for Building Systems (β Version)

September 3, 2018

The Ministry of Economy, Trade and Industry (METI) launched a Sub-working Group for Buildings under Working Group 1 (Systems, Technologies and Standardization) of the Study Group for Industrial Cybersecurity. In response, since its first meeting held on February 28, 2018, the sub-working group has been holding discussions on cybersecurity measures for building systems. METI hereby announces that the sub-working group formulated the “Guidelines for Cyber-Physical Security Measures for Building Systems (β Version).

1. Background

As part of the efforts for securing cybersecurity by industry, METI launched a Sub-working Group for Buildings, bringing together stakeholders in the field of buildings with a number of control devices, e.g., elevators and air conditioners, and since its first meeting held in February 2018, the sub-working group has been holding discussions on the development of guidelines for cybersecurity measures for building systems.

METI hereby announces that the sub-working group formulated the “Guidelines for Cyber-Physical Security Measures for Building Systems (β Version)” as its interim outcome.

2. Outline of the guidelines

The Guidelines for Cyber-Physical Security Measures for Building Systems (β Version) released here provide a compilation of threats, risks factors, and policy measures, which are expected to be important for building systems. Although the guidelines are a beta version, METI believes that the guidelines will help companies to assess the current security levels of buildings, and it expects many companies to utilize the guidelines broadly. Meanwhile, METI also considers it necessary to formulate new guidelines or directions for specific measures for conducting and implementing security, aiming to encourage companies to advance the implementation of security measures in their systems. The sub-working group will continue to discuss these new guidelines, including approaches to organizing them.
