Japan's Economic Security and Cybersecurity Strategy: Addressing Supply Chain and Critical Infrastructure Vulnerabilities

Executive Summary

Japan's approach to economic security is intricately linked to its cybersecurity strategy, focusing on safeguarding critical infrastructure and supply chains from cyber threats. The National Security Strategy (NSS) of Japan underscores the importance of economic security, particularly in the face of threats from authoritarian states like China. This report delves into the cybersecurity vulnerabilities Japan faces, the exploitation of these vulnerabilities, and the mitigation strategies being implemented to protect its economic interests.

Technical Information

Japan's National Security Strategy (NSS) identifies economic security as a pivotal aspect of national security, emphasizing the need to protect against threats from authoritarian states that disrupt the international order. The strategy highlights several key areas of concern, including supply chain vulnerabilities, threats to critical infrastructure, and the struggle for control over advanced technologies.

Supply chain vulnerabilities are a significant concern for Japan, as cyberattacks can exploit weaknesses embedded in the supply chain. This includes the potential for malicious software to be introduced during equipment installation or software updates. According to a report from Chambers Global Practice Guides, supply chain attacks rank as the second most concerning threat to enterprises in Japan. The Japanese government is acutely aware of these risks and is taking steps to mitigate them.

Critical infrastructure threats are another major focus of Japan's cybersecurity strategy. The government plans to establish a dedicated cybersecurity team to protect critical infrastructure, such as ports, railways, and airports, from cyberattacks by fiscal 2025, as reported by Nikkei Asia. Recent legal developments in Japan aim to fortify essential infrastructure services against cyber threats, with new systems set to become operational from May 2024 to mitigate risks like malware embedding.

In addition to these measures, Japan is investing in research and development to maintain strategic autonomy and prevent dependency on foreign technologies. This includes strengthening control over technology leaks and transfers, ensuring that Japan remains at the forefront of technological advancements.

Exploitation in the Wild

While specific instances of exploitation related to Japan's economic security strategy are not detailed in the sources, the general threat landscape includes state-sponsored cyberattacks targeting critical infrastructure and supply chains. Economic coercion through cyber means, such as disrupting supply chains or embedding malicious software in key systems, is a significant concern for Japan.

APT Groups using this vulnerability

The report does not specify particular Advanced Persistent Threat (APT) groups exploiting these vulnerabilities. However, it is well-documented that state-sponsored groups, particularly from authoritarian states, are actively targeting critical infrastructure and supply chains in various countries, including Japan.

Affected Product Versions

The report does not provide a detailed list of affected product versions. However, the focus is on critical infrastructure components and supply chain systems that are vulnerable to cyberattacks.

Workaround and Mitigation

Japan's approach to mitigating these cybersecurity threats includes strengthening supply chain resilience by collaborating with like-minded countries and promoting regional economic agreements. Enhancing the security of critical infrastructure through dedicated cybersecurity teams and legal frameworks is also a priority. Additionally, Japan is investing in advanced technology development to ensure strategic indispensability and control over technological advancements.
