Lawmakers in the ruling camp are preparing to submit a bill to the Diet next fall aimed at strengthening the government's cybersecurity to more quickly counter an increasing number of attacks, a member of the ruling bloc involved in the issue said Tuesday.

According to a tentative outline of the basic cybersecurity bill, the National Information Security Center, or NISC, would be given a legal foundation and its specific role would be fleshed out.

The bill would also seek to enhance cooperation among the country's 13 critical infrastructure operators in finance, electricity, petroleum, transportation and other industries.
