Japan's cyber defense is said to be vulnerable, so the government is exploring the introduction of an active cyber defense framework, according to sources.
ACD constantly patrols and monitors cyberspace to identify and respond quickly to suspicious communications and behaviors that could pose security threats. The United States and the United Kingdom are among the nations that have adopted the framework as part of their approach to cyber defense.
The framework is a bid to strengthen the nation's defense against cyber-attacks on critical infrastructure such as telecommunications and the power grid, the government sources said.
