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 comprehensive national regulation comprising 69 articles. It establishes a statutory framework for securing information systems by network operators and data processors within Chinese jurisdiction. Its primary purpose is to protect critical information infrastructure (CII), personal data, and national security through a risk-based approach emphasizing prevention, monitoring, and governance.
Key Components
- Three core pillars: Network Security (safeguards, testing), Data Localization & Personal Information Protection (local storage, cross-border assessments), and Cybersecurity Governance (executive duties, incident reporting).
- Applies to all network operators, CII entities, and those handling important data.
- Built on principles of real-time monitoring, multi-factor authentication, and state-approved cryptography (e.g., SM algorithms).
- Compliance via mandatory assessments and government evaluations for CII operators.
Why Organizations Use It
CSL ensures legal compliance, avoiding fines up to 5% of annual revenue, operational shutdowns, and reputational harm. It mitigates risks from data breaches while enabling strategic advantages like consumer trust, operational efficiency via edge computing, and innovation through local R&D. Essential for market access in China.
Implementation Overview
Phased approach: gap analysis, architectural redesign (local data centers, SIEM), governance setup, and continuous testing. Targets network operators, CII firms, and foreign entities with Chinese users across industries. Requires executive sponsorship, training, and MIIT-approved evaluations for sustained compliance.
WCAG Details
What It Is
Web Content Accessibility Guidelines (WCAG) is the W3C's international standard for web accessibility. It provides technology-agnostic, testable success criteria to make web content perceivable, operable, understandable, and robust for people with disabilities. Structured as a layered model with principles, guidelines, and criteria at levels A, AA, AAA.
Key Components
- Four POUR principles: Perceivable, Operable, Understandable, Robust.
- 13 guidelines and ~80 success criteria (WCAG 2.2).
- Informative techniques, understanding docs, and Quick Reference.
- Conformance claims require full pages, complete processes, accessibility-supported tech, non-interference.
Why Organizations Use It
- Meets legal mandates (ADA, Section 508, EN 301 549, EAA).
- Reduces litigation risk, improves UX/SEO, expands market reach.
- Enhances reputation, procurement eligibility, business outcomes like higher conversions.
Implementation Overview
- Phased: assessment, policy, training, tooling (axe, WAVE), audits, monitoring.
- Applies to all org sizes/industries; AA common target.
- No formal certification; self-assess via VPAT/ACR, audits.
