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 by the government which bears a responsibility for protection of critical infrastructure and by critical infrastructure operators which independently carry out relevant protective measures, and the 4th edition was published in 2017.
This document identifies the 14 sectors as critical infrastructure and it expects stakeholders to undertake the five measures as below.

  1. Development and penetration of safety principles
  2. Enhancement of information sharing system
  3. Reinforcement of incident response capacity
  4. Risk management and preparation of incident readiness
  5. Buildingup of basis of critical infrastructure protection

Outreach Activity

ASEAN-Japan Cybersecurity Policy Meeting has been established since 2009 with the aim to promote and strengthen cybersecyruty cooperation and collaboration between ASEAN Member States and Japan. The area of collaboration includes cyber exercise, awareness raising, capacity building and so on. A part of the outcome of the activity is shown as below.

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.
