China's MIIT Unveils Color-Coded System for Data Security Incidents

China's MIIT Unveils Color-Coded System for Data Security Incidents

China's Ministry of Industry and Information Technology (MIIT) has recently introduced an approach to handling data security incidents: a color-coded action plan. This system is aimed at improving the nation's response to data security events, ensuring prompt and effective action to mitigate and eliminate potential hazards and losses. This blog post delves into the intricacies of this new framework, providing insights into its potential impact and efficacy.

The Color-Coded System Explained

The new system categorizes data security incidents into four hierarchical levels based on their scope and severity:

  1. Red (Level I - Especially Significant): This level applies to events causing widespread shutdowns, major economic losses (over 1 billion yuan), or affecting the personal information of over 100 million individuals. It targets incidents resulting in serious anomalies lasting more than 24 hours.
  2. Orange (Level II - Significant): Targeting situations like shutdowns and operational interruptions exceeding 12 hours, this level is activated for economic losses between 100 million and 1 billion yuan, or when over 10 million individuals' personal information is compromised.
  3. Yellow (Level III - Large): This level focuses on events causing operational interruptions over eight hours, with economic losses ranging from 50 million to 100 million yuan. It's applicable when personal data of more than 1 million individuals is affected.
  4. Blue (Level IV - General): Aimed at minor events causing less significant operational interruptions and economic losses under 50 million yuan, this level is for incidents affecting less than 1 million individuals' personal data​​.

Implementation and Compliance

To ensure the effective application of this system, companies affected by data security incidents are required to assess the severity and report serious cases immediately to local industry supervision departments. This process involves not omitting, concealing, or falsifying any facts related to the incident. The draft rules of this system emphasize the importance of transparency and prompt reporting in managing data security threats​​.

Reporting Structure

The reporting structure under this new system mandates that incidents assessed as particularly major or significant must be reported within specific time frames: within 10 minutes by phone and 30 minutes in writing. Depending on the activated response level (Red or Orange), the local industry regulatory department must then report the matter to the MIIT. This structured approach is expected to ensure a more coordinated and efficient response to data security incidents​​.


China's MIIT's color-coded action plan represents a step in strengthening the nation's data security posture. By categorizing incidents based on severity and establishing clear reporting guidelines, this system promises to enhance the ability to respond effectively to various data security challenges. The success of this initiative, however, will depend on its implementation and the cooperation of all stakeholders in adhering to the prescribed guidelines. As the rules are open for public comments until January 15, 2024, it will be interesting to see how this system evolves and impacts data security management in China.
