What is the primary objective of **CSL (Cyber Security Law of China)**?

**The primary objective of CSL is to establish a nationwide statutory framework for securing information systems, enforcing network security, data localization, and cybersecurity governance for all entities processing data in China.** Enacted on **June 1, 2017**, with 69 articles, it mandates technical safeguards like firewalls and SOC monitoring (**network security**), storage of **Critical Information Infrastructure (CII)** and **important data** in Mainland China with security assessments for cross-border transfers (**data localization & PIP**), and executive accountability with incident reporting (**cybersecurity governance**).

Who is legally or professionally required to comply with **CSL (Cyber Security Law of China)**?

**All network operators, CII operators, data processors of important data, and foreign enterprises serving Chinese users must comply with CSL.** This includes entities owning networks for public services (e.g., **Tencent Cloud**, **Alibaba Cloud**), operating systems vital to national security or public welfare (e.g., power grids, banking cores), handling large-scale personal or **important data** (e.g., e-commerce platforms like JD.com), and foreign services like **Microsoft 365** or **Zoom** with Chinese users.

Does **CSL (Cyber Security Law of China)** require an external audit or third-party certification?

**CSL requires government-approved security evaluations and certifications for CII operators, including third-party testing but no universal external audit mandate.** **Article 20** demands penetration testing and vulnerability scanning on CII assets, while CII operators must submit **Security Protection Capability Test (SPCT)** reports to **MIIT** via certified agencies; **China Information Security Certification (CISC)** applies where specified.

How often should an assessment for **CSL (Cyber Security Law of China)** be performed?

**CSL mandates periodic security testing and real-time monitoring, with full re-assessments triggered within 60 days of regulatory amendments.** Ongoing requirements include real-time log ingestion via **SIEM**, quarterly compliance workshops, annual CSL reports, and **Article 20** testing for CII assets, plus re-assessment post-incidents or State Council updates to **important data** lists.

What are the consequences of non-compliance with **CSL (Cyber Security Law of China)**?

**Non-compliance with CSL incurs fines up to 5% of annual revenue, business suspensions, license revocations, operational shutdowns, and legal exposure.** The 2022 amendment escalated penalties; examples include a CNY 150 million fine for data non-localization and service blocks for cloud providers, plus reputational damage and PIPL-linked lawsuits.

An **CSL (Cyber Security Law of China)** be mapped to other international frameworks?

**Yes, CSL can be mapped to international frameworks like ISO 27001 and NIST for aligned implementation.** Its policy suite, controls (e.g., **Article 21** network security), and Annex A mappings support audit readiness; organizations use these for **China Innovation Centers** and hybrid architectures meeting global standards.

What is the first step to begin implementing **CSL (Cyber Security Law of China)**?

**The first step is Phase 0 pre-engagement: secure executive sponsorship and conduct regulatory baseline mapping.** Establish a C-suite charter, cross-functional steering committee, and catalog of applicable CSL articles cross-referenced to PIPL/DSL, preventing scope creep and aligning resources.

What is the primary objective of **ISO 28000**?

**ISO 28000 specifies requirements for establishing, implementing, maintaining, and continually improving a security management system (SMS) for supply chain security.** It provides a risk-based framework using the PDCA cycle to identify threats, vulnerabilities, and interdependencies across supply chains, select proportionate controls, and ensure continual improvement through leadership commitment, performance evaluation, and corrective actions.

Who is legally or professionally required to comply with **ISO 28000**?

**No organizations are legally required to comply with ISO 28000, as it is a voluntary international standard.** Professionally, it applies to any organization—regardless of size or sector—involved in supply chains, including logistics, manufacturing, retail, pharmaceuticals, ports, and 3PL providers, where contractual obligations, customs programs, tenders, or insurance demands necessitate demonstrable security management.

Does **ISO 28000** require an external audit or third-party certification?

**ISO 28000 does not require external audit or third-party certification, but supports them for conformity verification.** Certification follows ISO 28003 guidelines via accredited bodies (e.g., ANAB), involving Stage 1 (documentation review) and Stage 2 (implementation audit), with annual surveillance audits for three-year validity; internal audits suffice for self-assurance.

How often should an assessment for **ISO 28000** be performed?

**Risk assessments under ISO 28000 must be maintained continuously, with formal reviews at planned intervals or upon changes.** Internal audits occur via a risk-based program (e.g., annually for high-risk areas), management reviews at least yearly, and risk reassessments triggered by incidents, supply chain changes, or external factors like geopolitical shifts.

What are the consequences of non-compliance with **ISO 28000**?

**Non-compliance with ISO 28000 incurs no direct legal penalties, as it is voluntary.** Indirect consequences include supply chain disruptions from theft/sabotage, lost contracts, higher insurance premiums, regulatory scrutiny in trade programs, reputational damage, and financial losses from incidents, underscoring its role in risk mitigation.

An **ISO 28000** be mapped to other international frameworks?

**Yes, ISO 28000:2022 aligns with the High Level Structure (HLS), enabling mapping to compatible management systems.** Its PDCA cycle, risk-based approach (aligned with ISO 31000), and clauses 4-10 facilitate integration with standards sharing HLS, supporting unified audits, shared risk registers, and governance.

What is the first step to begin implementing **ISO 28000**?

**The first step is securing executive sponsorship and conducting a diagnostic gap analysis.** Appoint a Senior Responsible Owner, map supply chain context (internal/external issues, interested parties, scope), review existing processes against clauses 4-10, and produce a prioritized risk register to inform the implementation roadmap.
