[Integration with Business Continuity](#section-4) 6. [Audit Considerations](#section-5) 7. [Continuous Improvement](#section-6) 8. [Conclusion](#section-7) [ISO 27001](/solutions/oss/compliance/iso-27001) has become the de facto international standard for information security management. Achieving and maintaining certification demonstrates to customers, regulators, and partners that an organisation takes security seriously. Offline storage supports several key controls within the ISO 27001 framework. ## Understanding ISO 27001 ISO 27001 establishes requirements for an Information Security Management System. Rather than prescribing specific technologies, the standard requires organisations to: - Identify information security risks - Select appropriate controls to address those risks - Implement and operate the controls effectively - Monitor and continuously improve security posture The standard's Annex A contains 93 controls across four categories: organisational, people, physical, and technological. Offline storage is relevant to multiple controls across these categories. ## Relevant Controls Several Annex A controls are directly supported by offline storage: - **A.8.10 Information deletion**: Offline storage with physical access controls enables secure deletion with full audit trails - **A.8.13 Information backup**: Air-gapped backups address requirements for backup protection and recovery capability - **A.8.24 Use of cryptography**: Offline vaults combine encryption with physical isolation for defence in depth - **A.7.10 Storage media**: Physical controls over storage media are inherent in offline vault design - **A.5.33 Protection of records**: Long-term record protection benefits from offline storage isolation ## Risk Assessment and Treatment ISO 27001 requires risk-based decision-making. For the highest-risk information assets, the risk assessment process often identifies that network exposure represents an unacceptable residual risk regardless of other controls applied. In these cases, offline storage represents a risk treatment option that addresses the root cause: removing the data from the attack surface entirely. This is not about layering more controls on connected systems. It is about eliminating the exposure. ## Supporting the Statement of Applicability The Statement of Applicability documents which controls an organisation has selected and why. Offline storage provides clear justification for control selections related to: - Backup and recovery capabilities - Protection of high-sensitivity information - Physical and environmental security - Cryptographic controls Auditors appreciate controls that are easily verified and clearly effective. Physical disconnection is both. ## Integration with Business Continuity ISO 27001 requires integration with [business continuity](/solutions/oss) planning. Offline storage supports continuity objectives by ensuring that recovery is possible regardless of the scope or sophistication of a cyber attack. For organisations also certified to ISO 22301 for business continuity, offline storage provides the guaranteed recovery point that continuity plans require. When the worst happens, having known-good backups that cannot have been compromised is invaluable. ## Audit Considerations During ISO 27001 audits, organisations must demonstrate that controls are operating effectively. Firevault's comprehensive audit logging provides evidence of: - Access control effectiveness - Backup procedures being followed - Encryption implementation - Physical security measures This documentation supports efficient audits and clear compliance demonstration. ## Continuous Improvement ISO 27001 requires continuous improvement of the ISMS. As threats evolve, control effectiveness must be reassessed. The addition of offline storage to an existing security architecture represents a measurable improvement in protection for critical information assets. ## Conclusion ISO 27001 certification requires demonstrating appropriate controls for identified risks. For organisations handling high-sensitivity information, offline storage addresses multiple control requirements while providing protection that auditors and assessors recognise as effective. As part of a comprehensive ISMS, Firevault supports both initial certification and ongoing compliance.
