Amended Date: 2026.01.07 
Article 1 These Regulations are prescribed pursuant to Paragraph 3, Article 7 of the Cyber Security Management Act (hereinafter referred to as the “Act”). Info
Article 2 The cyber security responsibility levels of government agencies and specific non-government agencies (hereinafter referred to as “agencies”) shall, from highest to lowest, be classified as Level A, Level B, Level C, Level D, and Level E.
Article 3 The Executive Yuan shall, every three years, approve its own cyber security responsibility level and sub-mit it to the competent authority for recordation. Agencies directly under the Executive Yuan shall, every three years, submit the cyber security responsibility levels of their own, their subordinate or supervised government agencies, and the specific non-government agencies under their jurisdiction to the competent authority for approval.
Special municipality and county(city) governments shall, every three years, submit the cyber security responsibility levels of their own, their subordinate or supervised government agencies, and the following entities under their jurisdiction: township (town, city) offices, district offices of indigenous districts in special municipalities, township (town, city) representative councils, and representative councils of in-digenous districts in special municipalities, as well as the subordinate or supervised government agencies of the foregoing offices and councils, and shall report them to the competent authority for approval. Spe-cial municipality and county(city) councils shall, every three years, submit their own cyber security re-sponsibility levels to the competent authority for approval.
The Office of the President, the National Security Council, the Legislative Yuan, the Judicial Yuan, the Examination Yuan, and the Control Yuan shall, every three years, approve the cyber security responsibility levels of their own, their subordinate or supervised government agencies, and the specific non-govern-ment agencies under their jurisdiction, and submit them to the competent authority for recordation.
Where an agency is required to change its original cyber security responsibility level due to organizational or operational adjustments, it shall immediately handle the level change in accordance with the procedures set out in the preceding three paragraphs; the same shall apply where a new agency is established.
Where the government agencies under Paragraphs 1 through 3 handle the submission or approval of cyber security responsibility levels and deem it necessary to assign to a unit within a government agency or a specific non-government agency a level different from that of the agency itself, they may determine such level in accordance with Articles 4 through 10, taking into account the nature of the unit's business.

Article 11 Agencies shall handle the matters set out in Appendices 1 through 8 in accordance with their cyber secu-rity responsibility levels.
Information and communication systems developed by agencies themselves or through outsourcing shall be classified in accordance with Principles for Classifying Protection Requirement Levels for Information and Communication Systems set out in Appendix 9, and the control measures set out in Appendix 10, Security Baselines for Information and Communication Systems, shall be implemented accordingly. Where the central competent authority in charge of the relevant sector of a specific non-government agency deems it necessary to prescribe separate defense standards for specific types of information and communication systems, it may draft such defense standards and submit them to the competent authority for approval, after which those standards shall apply.
With the consent of their superior or supervisory agency, government agencies may apply mutatis mutan-dis the relevant provisions on defense standards prescribed by the central competent authority in charge of the relevant sector under the preceding paragraph; the same shall apply to other specific non-govern-ment agencies with the consent of their respective central competent authority in charge of the relevant sector.
Where an agency, in handling the matters set out in Appendices 1 through 8 or implementing the control measures set out in Appendix 10, encounters manifest difficulty in handling or implementing a specific matter or control measure due to technical limitations or factors such as the design, structure, or nature of an individual information and communication system, it may, with the consent of the agency that submits its level under the latter part of Paragraph 1 and Paragraph 2 of Article 3, or of the agency that approves its level under the former part of Paragraph 1 and Paragraph 3 of the same Article, and after reporting to the competent authority for recordation, be exempted from handling or implementing that matter or con-trol measure. Where the agency that submits the level falls under the foregoing circumstances, it may be exempted with the consent of the competent authority; where the agency that approves the level falls under such circumstances, it may be exempted after reporting to the competent authority for recordation.
Government agencies shall, in the manner designated by the competent authority, submit the implemen-tation status of the matters set out in Paragraphs 1 and 2.
The central competent authority in charge of the relevant sector may require the specific non-government agencies under its jurisdiction to submit the implementation status of the matters set out in Paragraphs 1 and 2 in the manner it designates.
Where agencies are required, as a result of amendments to Appendices 1 through 10, to add or modify items within a specified period, that period shall be calculated from the effective date of the amendments.
