ISO 27001:2022 8.14: Redundancy of information processing facilities
ISO 27001:2022 8.14 covers Redundancy of information processing facilities. The held text names 5 evidence records for it, the first being Statement of Applicability entry for control A.8.14, showing inclusion or justified exclusion, implementation status and the risks it.... The common gap an assessor flags is Redundant components exist but failover has never been tested.
Information processing facilities are to be built with enough redundancy to satisfy availability requirements. Purpose (stated in ISO/IEC 27002:2022): keeps information processing facilities running without interruption. As an Annex A reference control, it is compared with the controls determined in risk treatment (6.1.3 c) and recorded in the Statement of Applicability as included or excluded, with the justification and implementation status (6.1.3 d); implementation guidance is ISO/IEC 27002:2022 8.14.
What evidence supports 8.14?
- Annex A technological controlStatement of Applicability entry for control A.8.14, showing inclusion or justified exclusion, implementation status and the risks it treats
- Annex A technological controlDocumented availability requirements for business services and systems
- Annex A technological controlArchitecture diagrams showing redundancy such as dual providers, redundant networks, separate data centres, redundant power and load-balanced instances
- Annex A technological controlProcedures for activating redundant components, stating whether activation is automatic or manual
- Annex A technological controlFailover test records, preferably from production, showing failover worked as intended
Where this requirement comes from
This is our own statement of ISO 27001:2022 8.14, read from the copy we hold (licensed complete copy) and stated in our words, not the standard verbatim. The framework as we hold it.
Common gaps an assessor flags
- Redundant components exist but failover has never been tested
- Both internet links run through the same physical route or provider
- The secondary site has weaker security controls than the primary
- Single points of failure remain in supporting components such as DNS or identity services
How it maps to SOC 2
- CC9.1 high Redundancy of processing facilities mitigates disruption risk directly.
A link is a topical overlap with a confidence and a reason. It does not establish that meeting one requirement satisfies the other, and it is not certification.
