What It Is
The Cybersecurity Law of the People's Republic of China (CSL), enacted June 1, 2017, is a nationwide statutory regulation governing network operators, data processors, and critical infrastructure within China. It secures information systems through three pillars: network security, data localization, and cybersecurity governance, using mandatory technical, operational, and reporting requirements.
Key Components
- **Three pillarsNetwork security (safeguards, monitoring); Data localization for CII and important data; Governance with executive accountability.
- 69 articles covering testing, incident reporting, and cooperation.
- Built on risk classification of assets and data.
- Compliance via self-assessments, government evaluations, and audits like SPCT.
Why Organizations Use It
- Mandatory for China-touching entities to avoid 5% revenue fines, shutdowns.
- Builds trust with privacy-aware consumers and partners.
- Drives efficiency via zero-trust, automation; enables innovation in local R&D.
- Mitigates risks, enhances reputation in competitive market.
Implementation Overview
- Phased: Gap analysis, redesign (local clouds, SIEM, IAM), governance, testing.
- Targets network operators, CII, foreign firms with Chinese users.
- Requires training, reporting, continuous monitoring; CII needs MIIT certification.
MAS TRM Details
What It Is
MAS Technology Risk Management (TRM) Guidelines (January 2021) are supervisory guidance issued by Singapore's Monetary Authority of Singapore (MAS) for financial institutions. They provide a principles-based framework for managing technology and cyber risks, emphasizing proportional implementation based on risk profile, complexity, and criticality to ensure confidentiality, integrity, and availability (CIA).
Key Components
- 15 sections covering governance, risk frameworks, secure development, IT operations, resilience, access controls, cryptography, cyber defense, assessments, and audit.
- Synthesized 12 core principles like board accountability, asset inventory, third-party oversight, and defense-in-depth.
- No fixed controls; focuses on outcomes with continuous improvement.
- Compliance via supervisory review, not formal certification.
Why Organizations Use It
- Meets MAS supervisory expectations to avoid fines/enforcement.
- Enhances resilience against cyber threats and digital risks.
- Builds trust with regulators, customers, and stakeholders.
- Enables secure innovation in digital finance.
Implementation Overview
- Risk-based rollout: asset inventory, governance setup, control mapping.
- Applies to all MAS-supervised FIs; scalable by size.
- Involves policies, training, testing; audited internally.
