标榜“主动防御” 实为“先发制人”：警惕日本加速军事松绑的危险图谋

Core Viewpoint - Japan is shifting its cybersecurity strategy from a defensive posture to a proactive stance, allowing for preemptive actions against perceived cyber threats, which may escalate tensions in regional and global cybersecurity landscapes [1][2][4]. Group 1: Legislative and Strategic Changes - The Japanese government has passed a new cybersecurity strategy that authorizes police and the Self-Defense Forces to take offensive measures in response to cyberattacks [1][2]. - The "Proactive Defense" legislation allows the government to preemptively invade or destroy the networks of alleged attackers, marking a significant shift in Japan's approach to cybersecurity [2][3]. - This new strategy establishes a military principle of preemptive action in cyberspace, blurring the lines between peace and war, and effectively undermining constitutional restrictions on military engagement [2][3]. Group 2: Organizational and Command Structure - Japan is integrating its cybersecurity forces by establishing a "National Cyber Coordination Office" under the Cabinet to manage national cybersecurity resources and policies [3]. - The strategy aims to create a unified command mechanism that combines the capabilities of police, military, and intelligence agencies into a cohesive "integrated attack response force" [3]. - This restructuring indicates a shift in viewing cyberspace as a strategic domain where state power can be exercised directly, rather than merely a public or economic space [3]. Group 3: Geopolitical Implications - Japan's cybersecurity strategy emphasizes a confrontational stance against perceived threats from neighboring countries and positions itself as a key player in the Western cybersecurity framework in East Asia [4]. - The strategy includes building mechanisms for data sharing and intelligence exchange with allied nations, transforming Japan's role from defensive to offensive in regional cybersecurity operations [4]. - This proactive approach raises security concerns for neighboring countries, as Japan may define its own "potential threats" and conduct cross-border cyber operations under the guise of defense [4].
