What is the primary objective of MLPS 2.0 (Multi-Level Protection Scheme)?

MLPS 2.0 (Multi-Level Protection Scheme) establishes a graded cybersecurity protection system for all network operators in China, ensuring security controls match the potential impact of system compromise on national security, social order, and public interests. Defined under Article 21 of the 2017 Cybersecurity Law and standards like GB/T 22239-2019, it classifies systems into five levels (1-5) based on harm severity to individuals, organizations, or the state. Objectives include preventing attacks, data breaches, and disruptions through technical, management, physical, and personnel controls, with extensions for cloud, IoT, big data, and industrial systems.

Who is legally or professionally required to comply with MLPS 2.0 (Multi-Level Protection Scheme)?

All network operators in mainland China must comply with MLPS 2.0 (Multi-Level Protection Scheme), including domestic enterprises, foreign-invested firms, and multinationals with local systems. This encompasses operators of IT networks, cloud platforms, mobile apps, IoT, big data, and industrial controls. Critical sectors like finance, energy, telecom, and healthcare face heightened scrutiny, often at Level 3+. Enforcement by Public Security Bureaus (PSBs) applies universally, with no employee or revenue thresholds—classification drives obligations.

Does MLPS 2.0 (Multi-Level Protection Scheme) require an external audit or third-party certification?

Yes, MLPS 2.0 (Multi-Level Protection Scheme) mandates external security reviews by licensed Chinese firms for Level 2+ systems, targeting a minimum score of 75/100. Operators submit documentation (architecture, policies, risk assessments) to PSBs for approval. Level 3+ requires annual evaluations; Level 2 biennial. No formal "certification" exists, but PSB filing and passing audits are required for operation.

How often should an assessment for MLPS 2.0 (Multi-Level Protection Scheme) be performed?

MLPS 2.0 (Multi-Level Protection Scheme) requires periodic re-evaluations scaling by level: biennial for Level 2, annual for Level 3, semi-annual for Level 4, and as mandated for Level 5. Self-assessments occur continuously, with third-party audits for Level 2+ per schedule. Reassess upon major changes like architecture shifts or cloud migrations to maintain PSB approval.

What are the consequences of non-compliance with MLPS 2.0 (Multi-Level Protection Scheme)?

Non-compliance with MLPS 2.0 (Multi-Level Protection Scheme) triggers fines up to 100,000 yuan, operational suspensions, system shutdowns, and intensified PSB inspections. Enforcement links to license renewals; severe cases involve blacklisting or criminal liability. Examples include RMB 50,000 fines post-hacks and RMB 223 million for banks failing data controls.

An MLPS 2.0 (Multi-Level Protection Scheme) be mapped to other international frameworks?

Yes, MLPS 2.0 (Multi-Level Protection Scheme) control domains map closely to international frameworks like ISO 27001 and NIST CSF. Organizational, people, physical, and technological controls align with ISO Annex A; risk treatment plans support MLPS grading. However, MLPS adds prescriptive grading, PSB oversight, and data localization absent in voluntary standards.

What is the first step to begin implementing MLPS 2.0 (Multi-Level Protection Scheme)?

The first step for MLPS 2.0 (Multi-Level Protection Scheme) implementation is conducting a provisional self-assessment to classify systems into Levels 1-5 based on impact. Inventory networks, assess harm to national security/social order per GB/T 22239-2020, document rationale, and prepare for Level 2+ PSB filing within 30 days.

What is the primary objective of ISO 27701?

ISO 27701 specifies requirements and guidance for establishing, implementing, maintaining, and continually improving a Privacy Information Management System (PIMS). It extends ISO 27001 by adding privacy controls in Annex A (PII controllers) and Annex B (PII processors), focusing on PII lifecycle management, risk assessment, data subject rights, and demonstrable accountability through records like RoPA and SoA.

Who is legally or professionally required to comply with ISO 27701?

No organization is legally required to comply with ISO 27701, as it is a voluntary international standard. It applies professionally to any entity acting as a PII controller or PII processor handling personally identifiable information, particularly those seeking certification to demonstrate privacy governance or align with laws like GDPR via Annex D mappings.

Does ISO 27701 require an external audit or third-party certification?

ISO 27701 certification is achieved through external audits by accredited third-party certification bodies. The process involves Stage 1 (documentation review) and Stage 2 (implementation verification), often integrated with ISO 27001 audits; the 2025 edition enables standalone certification over a three-year cycle with annual surveillance audits.

How often should an assessment for ISO 27701 be performed?

ISO 27701 requires continual assessment through internal audits, management reviews, and performance evaluation per Clause 9. Certification maintenance demands annual surveillance audits, with full recertification every three years, alongside ongoing risk assessments and PDCA-driven improvements.

What are the consequences of non-compliance with ISO 27701?

Non-compliance with ISO 27701 results in loss of certification, failed surveillance audits, or audit nonconformities requiring corrective actions. As a voluntary standard, it carries no direct legal penalties, but exposes organizations to privacy law fines (e.g., GDPR up to 4% global turnover) due to inadequate PIMS evidence.

Can ISO 27701 be mapped to other international frameworks?

Yes, ISO 27701 includes annexes for mapping to frameworks like GDPR (Annex D), ISO/IEC 29100 (Annex C), and ISO/IEC 27018/29151 (Annex E). Annex F details its relationship to ISO 27001/27002, enabling integrated control selection and evidence reuse.

What is the first step to begin implementing ISO 27701?

The first step is defining PIMS context and scope per Clause 4, identifying PII processing activities and controller/processor roles. Conduct a gap analysis against Clauses 4–10 and Annex A/B controls, producing a scope statement, RoPA, and initial risk assessment.
