Japan has announced an emergency cybersecurity package that will create specialist response teams and use artificial intelligence to help identify weaknesses after a wave of data breaches.

Prime Minister Sanae Takaichi presented the plan at a ministerial meeting Friday, saying the government and businesses needed to strengthen their ability to respond, The Associated Press reported. The package is valued at 10 billion yen, about $63 million, according to AP.

The announcement follows unauthorized access and customer-data leaks involving companies and government agencies. It sets out measures the government plans to take; it does not mean those defenses are all operating yet.

Specialists and a rescue team

The Ministry of Economy, Trade and Industry plans to establish an expert team by the end of November. AP reported that members will use AI to help detect security weaknesses and counter hackers, while working with technology companies and foreign partners.

A separate public-private cyber rescue team is intended to help companies respond when an attack occurs. Another group will help vulnerable businesses strengthen their defenses, AP reported. Japan’s Impress Watch also described the planned response teams.

AI can help find patterns and potential flaws, but announcing a tool or team does not establish that any particular breach has been solved or that future intrusions can be prevented.

The broader cyber strategy

The government also plans to increase its capability for what AP described as active cyber defense, including access to servers used by hackers. AP reported that Japan legalized the measure in October.

Takaichi cited the effect of unauthorized access and data leaks on daily life and business activity, according to AP. The reporting did not identify a single perpetrator behind all of the incidents cited as context for the package.

Details such as which companies will receive help and the results of the new teams’ work remain to be established as the measures are put into practice.
