What is ISO 27001:2022 Annex A 8.14 Redundancy of information processing facilities in ISO 27001?
Annex A 8.14 requires information processing facilities to have sufficient redundancy. This documented process ensures systems meet availability requirements. You must integrate these procedures into existing tools like SharePoint. It involves planning for component failures without relying on external software platforms. This maintains operational continuity through management oversight.
Auditor’s Eye: The Shortcut Trap
Many organisations rely on automated SaaS platforms to track availability. These platforms show a green tick but lack internal testing evidence. Auditors reject these black box records. We want to see your native repositories. Show me Jira tickets for your last failover test. Confluence must host your architecture diagrams. Relying on SaaS decouples security from daily work. Authentic evidence resides in your document versions. This proves you own the resilience process.
| ISO 27001:2013 Control | ISO 27001:2022 Control | Nature of Change |
|---|---|---|
| A.17.2.1 Availability of info processing facilities | Annex A 8.14 Redundancy of info processing facilities | Shift from generic availability to specific redundancy requirements. Emphasises resilience of facilities. |
How to Implement ISO 27001:2022 Annex A 8.14 (Step-by-Step)
Redundancy is a documented state of system resilience. It is not a software installation. You must use existing organisational tools to build a audit trail. This ensures technical teams follow security protocols naturally. Follow these steps for implementation:
- Define availability targets in a SharePoint document.
- Link targets to your Business Impact Analysis.
- Draft technical redundancy diagrams in Confluence.
- Record system configurations for failover clusters.
- Create Jira tickets for quarterly failover tests.
- Document test outcomes in the Jira comments.
- Assign technical owners to maintain redundant hardware.
- Review resilience during monthly management meetings.
ISO 27001:2022 Annex A 8.14 Audit Evidence Checklist
Focus on manual records and internal document versions. These prove human oversight and intent. Maintain these in your primary organisational tools:
- Business Impact Analysis in SharePoint.
- Redundancy architecture diagrams in Confluence.
- Failover test logs in Jira.
- Management meeting minutes reviewing resilience.
- Service Level Agreements with hardware vendors.
- Historical uptime reports from internal monitoring.
Relational Mapping
Annex A 8.14 depends on several core ISO 27001 controls:
- Annex A 5.30: ICT readiness for business continuity.
- Annex A 8.13: Information backup requirements.
- Annex A 8.20: Network security and redundancy.
Auditor Interview
Auditor: How do you verify your redundancy works?
Manager: We perform quarterly failover tests. We track every test in Jira.
Auditor: Where is the design documentation for your cluster?
Manager: All architecture diagrams reside in Confluence. You can see the version history there.
Auditor: How do you define the required level of redundancy?
Manager: Our SharePoint BIA defines the availability targets for each service.
Common Non-Conformities
| Failure Mode | Description | Corrective Action |
|---|---|---|
| Automated Complacency | Relying on a SaaS platform tick without internal test logs. | Record manual failover tests in Jira. |
| Single Point of Failure | Systems lack redundancy for power or networking components. | Update Confluence diagrams to identify gaps. |
| Stale Documentation | Redundancy plans exist but do not match live hardware. | Implement monthly document reviews in SharePoint. |
Frequently Asked Questions
What is Annex A 8.14 in ISO 27001?
The Bottom Line: Annex A 8.14 requires information processing facilities to have sufficient redundancy to meet availability needs. You must document these processes within internal tools like SharePoint. This ensures resilience through management oversight. It avoids reliance on unverified external software platforms.
How do you prove redundancy to an auditor?
The Bottom Line: Present failover test logs stored in Jira tickets. Show architecture diagrams with version history in Confluence. Auditors prefer seeing internal records over SaaS dashboards. These documents prove your team manages the technical resilience personally.
What is the difference between backup and redundancy?
The Bottom Line: Redundancy provides immediate system failover to maintain active operations. Backups provide data recovery after a failure occurs. Annex A 8.14 specifically targets the availability of the processing facilities. You must manage both through documented internal procedures.
