The government crafted a new cybersecurity strategy Wednesday as it steps up preparations for the Tokyo Olympic and Paralympic Games in 2020.
During a meeting at the prime minister’s office, it also decided to introduce a five-stage index to classify the severity of cyberattacks to help people understand the magnitude of threats and take necessary action.
The five stages are based on how long it will take to recover, the size of the area affected as well as whether people were injured or forced to evacuate. The lowest level of 0 indicates “no impact” while the highest level of 4 implies an “extremely grave impact.”
