Implementing ISO 27001 Annex A 5.31 involves identifying and documenting all relevant legislative, regulatory, and contractual obligations. The primary implementation requirement is maintaining an up-to-date legal register that maps specific laws to internal security controls, ensuring the business benefit of reduced legal liability and demonstrable compliance with global data protection standards.
ISO 27001 Annex A Legal, statutory, regulatory and contractual requirements Implementation Checklist
Use this implementation checklist to achieve compliance with ISO 27001 Annex A 5.31. True compliance involves a forensic review of the specific legislative frameworks and contractual clauses that bind your organisation, rather than relying on a generic “Global Law” template provided by a GRC vendor.
1. Define Legislative Jurisdictions
Control Requirement: The organisation must identify the specific laws and regulations applicable to its information security operations.
Required Implementation Step: Consult with legal counsel to explicitly list every country and state where you process data or have physical assets. You must document the specific computer misuse, data protection, and electronic transaction acts applicable to those territories, rather than guessing based on your website traffic.
Minimum Requirement: A documented list of jurisdictions (e.g., “UK DPA 2018”, “EU GDPR”, “California CCPA”) verified by a qualified legal professional.
2. Construct a Detailed Legal Register
Control Requirement: All relevant legal, statutory, regulatory, and contractual requirements must be documented and kept up to date.
Required Implementation Step: Create a centralised spreadsheet or database known as the “Legal Register”. Map specific clauses of legislation (e.g., “GDPR Article 32”) directly to your internal policies and controls, ensuring you can prove exactly how you satisfy each requirement.
Minimum Requirement: A version-controlled Legal Register with columns for “Legislation”, “Specific Requirement”, “Internal Control Owner”, and “Compliance Status”.
3. Document Intellectual Property Rights (IPR) Compliance
Control Requirement: Procedures must be implemented to ensure compliance with legislative, regulatory, and contractual requirements on the use of material which may be subject to intellectual property rights.
Required Implementation Step: Run a software asset management audit to reconcile installed software against purchased licenses. You must physically verify that you possess valid licenses for every proprietary tool in use and remove any “cracked” or unauthorised shareware immediately.
Minimum Requirement: A license reconciliation report showing a surplus or exact match of licenses to installations.
