CSL (Cyber Security Law of China) Details
What It Is
The Cybersecurity Law of the People’s Republic of China (CSL), enacted on June 1, 2017, is a nationwide statutory regulation comprising 69 articles. It governs network operators, Critical Information Infrastructure (CII) operators, and data processors handling personal or important data in China. CSL adopts a pillar-based approach focused on securing information systems, localizing data, and enforcing governance.
Key Components
- Three pillarsNetwork Security** (safeguards, monitoring), Data Localization & PIP (local storage, cross-border assessments), Cybersecurity Governance (executive accountability, incident reporting).
- Classifies assets as CII or important data.
- Built on mandatory technical controls and cooperation with authorities.
- Compliance model includes self-assessments, government evaluations, and audits like SPCT.
Why Organizations Use It
CSL is legally binding, with risks like 5% revenue fines, service shutdowns, and lawsuits. It drives trust among Chinese consumers and partners, boosts efficiency via microservices and SOAR, and enables innovation through local R&D and sandboxes. Enhances reputation and market leadership.
Implementation Overview
Follows phased framework: stakeholder alignment, gap analysis, technical redesign (e.g., ZTA, SIEM, SM cryptography), governance (training, DPOs), and testing/certification. Applies to all with Chinese users, especially MNCs and CII operators. Demands local data centers and continuous monitoring.
WELL Details
