What is the primary objective of ISO 27018?

ISO 27018 provides a code of practice for protecting PII in public clouds where the provider acts as a PII processor. It extends ISO 27001 and ISO 27002 with ~25–30 privacy-specific controls addressing cloud risks like multi-tenancy, subprocessor transparency, consent, purpose limitation, data minimization, breach notification, and restrictions on secondary PII use (e.g., no marketing without consent). The 2019 edition aligns with ISO 27002:2013, emphasizing processor obligations across the PII lifecycle.

Who is legally or professionally required to comply with ISO 27018?

No organization is legally required to comply with ISO 27018, as it is a voluntary code of practice. It applies professionally to public cloud service providers (CSPs) acting as PII processors, including hyperscalers like Microsoft Azure. Controllers use it for vendor due diligence; adoption is driven by procurement demands, regulatory alignment (e.g., GDPR Article 28), and market differentiation.

Does ISO 27018 require an external audit or third-party certification?

*ISO 27018 does not support standalone certification; controls are assessed within ISO 27001 audits by accredited bodies under ISO/IEC 17021 and ISO/IEC 27006. CSPs include ISO 27018 controls in their Statement of Applicability (SoA)*; auditors validate during Stage 1/2 audits, with certificates referencing both standards.

How often should an assessment for ISO 27018 be performed?

Assessments for ISO 27018 occur via annual surveillance audits and full recertification every three years as part of ISO 27001 certification. Ongoing internal reviews align with ISMS continual improvement, addressing changes in cloud services, subprocessors, or risks.

What are the consequences of non-compliance with ISO 27018?

*ISO 27018 non-compliance carries no direct penalties, as it is not legally binding.* Indirect consequences include lost procurement opportunities, heightened regulatory scrutiny (e.g., GDPR fines for inadequate processor controls), elevated cyber insurance premiums, reputational damage, and prolonged customer security questionnaires.

Can ISO 27018 be mapped to other international frameworks?

Yes, ISO 27018 maps closely to frameworks like ISO 27017 (cloud security), ISO 27701 (PIMS), and regulations such as GDPR Article 28. Controls align with privacy principles (consent, transparency, data minimization) and processor obligations, enabling integrated ISMS implementations without standalone certification.

What is the first step to begin implementing ISO 27018?

Conduct a gap analysis against ISO 27018 controls within your existing or planned ISO 27001 ISMS. Review policies, SoA, contracts, subprocessors, PII lifecycle processes, and technical safeguards (e.g., encryption, logging) to identify deficiencies and develop a prioritized remediation roadmap.

What is the primary objective of ISO 22301?

ISO 22301 specifies requirements for establishing, implementing, maintaining, and continually improving a Business Continuity Management System (BCMS). It enables organizations to protect against, reduce the likelihood of, and recover from disruptive incidents while ensuring continuity of critical products and services, structured around a PDCA (Plan-Do-Check-Act) cycle across 10 clauses.

Who is legally or professionally required to comply with ISO 22301?

ISO 22301 applies to organizations of all sizes and sectors seeking resilience, with no universal legal mandate. Professional requirements arise in regulated sectors like utilities, transport, health, finance, and IT services, where it supports compliance with directives such as the EU NIS2 Directive for essential services providers.

Does ISO 22301 require an external audit or third-party certification?

ISO 22301 certification requires a two-stage external audit by an accredited third-party body. Stage 1 assesses readiness, Stage 2 verifies effectiveness (typically 6-8 weeks total), followed by 3-year validity with annual surveillance audits and internal audits.

How often should an assessment for ISO 22301 be performed?

ISO 22301 mandates internal audits at planned intervals, typically annually, plus management reviews. Performance evaluation under Clause 9 includes monitoring, measurement, and testing of BCMS, with the standard undergoing systematic review every 5 years and certification surveillance annually.

What are the consequences of non-compliance with ISO 22301?

Non-compliance with ISO 22301 exposes organizations to unmitigated disruptions, financial losses, reputational damage, and regulatory penalties. Certified organizations avoid these via resilience; uncertified ones risk sector-specific fines under frameworks like NIS2, plus 20% annual disruption probability leading to downtime costs.

Can ISO 22301 be mapped to other international frameworks?

Yes, ISO 22301 seamlessly maps to other frameworks via its Annex SL high-level structure. It aligns with standards like ISO 27001 for integrated management systems, sharing elements such as audits, reviews, and risk processes, enabling efficient IMS deployment.

What is the first step to begin implementing ISO 22301?

The first step is conducting a gap analysis of current practices against Clauses 4-10, starting with Clause 4 (Context of the Organization). This identifies internal/external issues, interested parties, and BCMS scope, followed by leadership commitment (Clause 5) and BIA under Clause 6.
