Frequently Asked Questions about ISO 27001 Supplier Security
What does ISO 27001 require for supplier security?
ISO 27001:
2022 covers supplier security in Annex A controls 5.19 to 5.22: A.5.19 requires an information security policy for supplier relationships. A.5.20 mandates contractual security requirements. A.5.21 requires monitoring of suppliers' information security performance. A.5.22 governs managing changes in the supply chain. ICT suppliers must additionally be addressed under A.5.23.
What do ISO 27001 controls A.5.19 to A.5.22 cover?
Controls A.5.19-A.5.22 form the ISO 27001 supplier security block: A.5.19 requires a written policy for supplier relationships and their access to company information. A.5.20 mandates binding security clauses in supplier contracts. A.5.21 requires regular supplier reviews. A.5.22 governs supplier changes and significant modifications to the supply chain.
How does ISO 27001 supplier management relate to DORA third-party requirements?
ISO 27001 and DORA complement each other in supplier management: ISO 27001 A.5.19‑5.22 provides the foundational framework for supplier assessment and monitoring. DORA extends this for financial entities with specific requirements for ICT third-party service providers: written contracts with defined service levels, exit strategies, audit rights, and reporting obligations for critical third-party providers. ISO 27001-compliant supplier management forms the operational foundation for DORA compliance.
How do you assess suppliers under ISO 27001?
ISO 27001-compliant supplier assessment covers multiple levels: initial assessment before contract (security questionnaire, certifications such as ISO 27001 or SOC 2), contractual security requirements, regular performance reviews (annually or upon significant changes), right to audit or access audit reports, and a defined process for handling supplier incidents. All results must be documented.
What does ISO 27001 require in supplier agreements?
ISO 27001 A.5.20 requires supplier contracts to establish security requirements: confidentiality clauses, access control and data security requirements, incident reporting obligations, compliance requirements (GDPR, sector-specific regulation), audit and review rights, secure data deletion provisions at contract end, and subcontractor rules. For ICT suppliers, additional requirements from A.5.23 apply.
How do ISO 27001 and TISAX differ for supply chain security?
ISO 27001 and TISAX address supply chain security from different perspectives: ISO 27001 is industry-agnostic and governs supplier security in controls A.5.19-A.5.22 with a focus on information security governance. TISAX (Trusted Information Security Assessment Exchange) is the automotive industry standard with more specific requirements for suppliers in vehicle development. Many automotive suppliers need both ISO 27001 compliance and TISAX assessment. Our consulting covers both standards.
