About NISC

The Cybersecurity Strategic Headquarters was established under the Cabinet in November, 2014 for the purpose of effectively and comprehensively promoting cybersecurity policies. The Cybersecurity Strategic Headquarters is headed by the Chief Cabinet Secretary, with his deputy - the Minister in charge of Cybersecurity - and composed of the Chairman of the National Public Safety Commission, the other relevant Ministers and knowledgeable experts from academia and business sectors.

National center of Incident readiness and Strategy for Cybersecurity, “NISC” has been established since 2015 which was formerly called National Information Security Center since 2005, under the same abbreviation “NISC”, as a secretariat of the Cybersecurity Strategy Headquarters, working together with the public and private sectors on a variety of activities to create a "free, fair and secure cyberspace". NISC plays its leading role as a focal point in coordinating intra-government collaboration and promoting partnerships between industry, academia, and public and private sectors.

NISC coordinates cybersecurity policy by formulating

  • Cybersecurity Strategy
  • Cybersecurity Policy for Critical Infrastructure Protection
  • Common Standard on Information Security Measures of Government Entities
  • Cybersecurity Human Resource Development Plan
  • Cybersecurity Research and Development Strategy etc.

NISC takes a role of a governmental CERT, and NISC and JPCERT/CC, as a CERT covering private entities, work together as a national CERT.

NISC consists of the following seven groups. The main activities are as follows.


Cybersecurity Strategy

The current Cybersecurity Strategy issued in September 2021 is the third one under the Basic Act on Cybersecurity. The Cybersecurity Strategy shows a basic position on cybersecurity policy, its objectives and its implementation for 3 years domestically and internationally. Overview of the Cybersecurity Strategy is as below.

The Basic Act on Cybersecurity

The Basic Act on Cybersecurity has been implemented since 2015 to promote the cybersecurity policy by

  • setting basic principles of cybersecurity policy
  • clarifying the responsibilities of the government, private entities, and citizens
  • stipulating the framework for cybersecurity policy such as the cybersecurity strategy formulation and the establishment of the Cybersecurity Strategic Headquaters.

Government Network


NISC has set the Common Standards on Information Security Measures of Government Entities to raise the level of information security for all governmental agencies and related agencies, as the baseline standard. Based on the standard, NISC oversees the status of implementation of it across agencies by audits.


NISC operates real-time government-wide monitoring team called the Government Security Operation Coordination team (GSOC). GSOC not only monitors malicious communications incoming to or outgoing from government owned systems but also works as information sharing framework among governmental entities. GSOC provides alerts and advice for the governmental entities when they detect suspicious signals or malware.

Critical Infrastructure

Since 2005, the ‘Cybersecurity Policy for Critical Infrastructure Protection’ has been set as a common action plan shared between the government, which bears responsibility for promoting independent measures by CI operators relating to CI cybersecurity and implementing other necessary measures, and CI operators which independently carry out relevant protective measures, and the new edition was published in 2022.
This document identifies the 14 sectors as critical infrastructure and it expects stakeholders to undertake the five measures as below.

  1. Enhancement of Incident Response Capability
  2. Maintenance and Promotion of the Safety Principles
  3. Enhancement of Information Sharing System
  4. Utilization of Risk Management
  5. Enhancement of the Basis for CIP

International Cooperation

As mentioned in the Cybersecurity Strategy of Japanese government, Japan strengthens collaboration with its ally and like-minded countries as well as multi-layered frameworks that enable the Japanese government to engage in practical international collaboration with their counterparts.
A part of the outcome of the activities in NISC as the national cybersecurity center is shown as below.


For further cybersecurity cooperation and capacity building in the ASEAN-Japan region, the activity result was summarized in the E-booklet.


NISC co-sealed “Shifting the Balance of Cybersecurity Risk: Principles and Approaches for Secure by Design Software”.


Other Projects

Enhancement of Information Sharing

In order to enhance the information sharing among relevant stakeholders in public and private sector, with the amendment of the Basic Act on Cybersecurity, the Cybersecurity Council was newly established in April 2019, composed of national government bodies, critical infrastructure operators, security vendors, and other related organizations. The amended Act imposes the obligation of confidentiality on the members of the Council and so on to encourage the willingness of information sharing.

General Framework for Secure IoT Systems

NISC has set the ‘General Framework for Secure IoT Systems’ in 2016 which clarifies the fundamental and essential security requirements for secure IoT systems.
