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 79 articles, it mandates technical safeguards like firewalls and real-time monitoring, requires Critical Information Infrastructure (CII) and important data storage in Mainland China, and imposes senior executive accountability under its three pillars.

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

CSL applies to all network operators, CII operators, data processors of important data, and foreign enterprises serving Chinese users. This includes network operators like cloud platforms (e.g., Alibaba Cloud), CII operators in power grids or banking, processors of large-scale personal data (e.g., e-commerce like JD.com), and foreign services (e.g., Microsoft 365) with Chinese digital footprints.

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

Yes, CSL requires government-approved security evaluations and certifications, such as the Multi-Level Protection Scheme (MLPS) certification for network operators, and China Information Security Certification (CISC) where applicable. Article 34 mandates annual security risk assessments; CII entities must use certified testing agencies for attestation.

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

CSL assessments must be conducted periodically, with security testing required ongoing and full re-assessments triggered by major system changes or security incidents. Real-time monitoring via SIEM is mandatory, alongside annual compliance reports, quarterly training, and incident-response drills to meet Article 25 immediate reporting requirements.

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

Non-compliance with CSL and related data laws incurs fines up to 5% of annual revenue, business license suspension, service shutdowns, and operational disruptions. Examples include the multi-billion CNY fine against Didi in 2022 for severe cybersecurity and data violations and API blocks for cloud providers; reputational damage and PIPL lawsuits add further exposure.

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

Yes, CSL can be mapped to international frameworks by aligning its controls, such as Annex A of ISO 27001, to CSL articles like network security (Article 21). Implementation frameworks recommend such mappings for audit readiness, integrating data localization with global standards while embedding CSL-specific requirements like SM cryptography.

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

The first step for CSL implementation is Phase 0: securing executive sponsorship and conducting regulatory baseline mapping. Establish a C-suite charter, cross-functional steering committee, and catalog of applicable CSL articles cross-referenced to related laws, preventing scope creep and aligning resources.

What is the primary objective of APRA CPS 234?

APRA CPS 234 requires regulated entities to maintain an information security capability commensurate with vulnerabilities and threats to information assets. This minimises the likelihood and impact of incidents on confidentiality, integrity, or availability (CIA) of information assets, including those managed by related parties or third parties (paragraphs 1, 15-16). Effective from 1 July 2019, it ensures continued sound operation of the entity.

Who is legally or professionally required to comply with APRA CPS 234?

APRA CPS 234 applies to all APRA-regulated entities, including authorised deposit-taking institutions (ADIs), general insurers, life companies, private health insurers, and RSE licensees. It covers Heads of groups on a group-wide basis, extending to non-regulated group entities (paragraphs 2-4). Foreign ADIs, Category C insurers, and eligible foreign life insurance companies comply only for Australian branch operations (paragraph 3).

Does APRA CPS 234 require an external audit or third-party certification?

APRA CPS 234 does not mandate external audit or third-party certification. It requires internal audit to review design and operating effectiveness of information security controls, including those of related parties and third parties, using appropriately skilled personnel (paragraphs 32-34). Entities may rely on third-party assurance if internal audit assesses its sufficiency for material-impact assets (paragraph 34).

How often should an assessment for APRA CPS 234 be performed?

APRA CPS 234 requires the testing program to be reviewed at least annually or upon material change to information assets or the business environment. Systematic testing of control effectiveness must occur with frequency commensurate with vulnerability/threat change rates, asset criticality/sensitivity, incident consequences, and exposure to untrusted environments (paragraphs 27, 31). Internal audit provides ongoing assurance (paragraph 32).

What are the consequences of non-compliance with APRA CPS 234?

Non-compliance with APRA CPS 234 exposes entities to APRA's prudential enforcement powers under relevant Acts. These include directions for remediation, heightened supervision, or other actions (paragraph 11). Entities must notify APRA within 72 hours of material incidents or 10 business days of unremediable material control weaknesses (paragraphs 35-36), triggering potential regulatory intervention.

Can APRA CPS 234 be mapped to other international frameworks?

Yes, APRA CPS 234's outcomes-based requirements can be mapped to frameworks like ISO 27001 and NIST Cybersecurity Framework. Its focus on governance, commensurate controls, systematic testing, and third-party oversight aligns with ISO 27001's ISMS and NIST's Identify-Protect-Detect-Respond-Recover functions, enabling operationalisation while meeting Board accountability and notification timelines (paragraphs 13, 27-36).

What is the first step to begin implementing APRA CPS 234?

The first step is for the Board to assume ultimate responsibility and approve an information security governance framework (paragraph 13). This includes defining roles/responsibilities (paragraph 14), identifying/classifying information assets by criticality and sensitivity (paragraph 20), and establishing a policy framework commensurate with threats (paragraphs 18-19).
