Purpose of ISO 27001:2022 Annex A 8.14
An ‘information processing facility’ (IPF) is a general term used to refer to any information and communications technology (ICT) infrastructure that handles data processing, such as IT equipment, software, and physical facilities.
IPFs are essential to sustaining business continuity and guaranteeing the efficient operation of an organisation’s ICT network(s). To boost resilience, organisations must put into action strategies that enhance the redundancy of their IPFs – for example, fail-safe techniques and procedures that decrease the risk of failure, misuse, or intrusion to systems and data.
Ownership of Annex A 8.14
ISO 27001:2022 Annex A 8.14 is concerned with an organisation’s capacity to continue operations in the event of critical or minor failures that may affect resilience. Therefore, the Chief Operating Officer, or an equivalent, should be responsible for this control.

Guidance on ISO 27001:2022 Annex A 8.14 Compliance
The primary objective of Annex A 8.14 is to enhance the accessibility of business services and information systems, which can be interpreted as any part of a network that facilitates the company’s operations.
ISO 27001:2022 Annex A 8.14 recommends duplication as the main way of acquiring redundancy across its various IPFs, notably through keeping a stock of spares, duplicate components (hardware and software) and extra peripheral devices.
Organisations should ensure that any failed IPFs are quickly detected and remedial action is taken swiftly, either by failing over to backup hardware or fixing the malfunctioning IPF promptly.
Organisations should take into account the following when designing and installing redundancy measures:
- Entering into commercial relationships with two distinct service providers can help minimise the risk of a full outage in the event of a critical incident, such as an ISP or VoIP provider.
- Adhering to best practices of redundancy when designing data networks (such as secondary DCs and redundant BUDR systems).
- Leveraging geographically disparate locations when outsourcing data services, particularly for file storage and/or data centre amenities, is essential.
- Purchase power systems that deliver redundancy either entirely or partially as required.
- Utilising load balancing and automatic fail-over between duplicate, redundant software components or systems increases real-time performance and resilience after a critical event. This is especially pertinent when employing an operational model with both public cloud and on-premise services. Testing redundant systems regularly in production mode ensures fail-over systems are functioning as intended.
- Duplicate physical ICT components, both within servers and file storage locations (RAID arrays, CPUs) and any functioning as a network device (firewalls, redundant switches), to ensure the continuity of service. Firmware updates should be conducted on all linked and redundant devices.
Supplementary Guidance on Annex A 8.14
ISO 27001:2022 Annex A Control 8.14 recognises the connection between reliable, redundant systems and business continuity planning (see ISO 27001:2022 Annex A 5.30), encouraging organisations to view them as part of the answer to common difficulties.
It is essential to consider that, with regards to business applications, it is immensely difficult to address major mistakes within the application itself (especially when using managed applications).

Changes and Differences from ISO 27001:2013
ISO 27001:2022 Annex A 8.14 supersedes ISO 27001:2013 Annex A 17.2.1 (Availability of Information Processing Facilities).
27001:2022 Annex A 8.14 marks a major advancement compared to 27001:2013 Annex A 17.2.1, with the difference between the two controls making up the most significant shift of the entire ISO 27001:2022 revision.
27001:2013 Annex A 17.2.1 offers a brief outline of the need for redundancy, while 27001:2022 Annex A 8.14 provides extensive instructions on how to implement it across on-premise, cloud-based, logical and physical components.
