Kimova AI ISO 27001 Auditing Series Technological Control A.8.14 Redundancy of Information Processing Facilities

In today’s Kimova AI ISO 27001 auditing series, we turn our focus to Technological Control A.8.14: Redundancy of Information Processing Facilities. This control emphasizes the importance of maintaining redundancy in critical information processing facilities, enabling organizations to ensure uninterrupted operations and data accessibility during infrastructure disruptions.

Control A.8.14: Redundancy of Information Processing Facilities

Redundancy in information processing facilities refers to the deployment of backup systems and alternative processing locations, ensuring that if a primary facility is compromised, essential services and data processing can continue without significant interruptions.

Key Aspects of Control A.8.14

1. Identifying Critical Information Processing Facilities
   • Explanation: Determine which facilities, systems, or infrastructure are essential to operational continuity, and develop redundancy plans for these components.
   • Example: A global bank identifies its core transaction-processing servers as critical and establishes secondary processing sites in geographically diverse locations to avoid disruptions.
2. Creating Redundant Infrastructure
   • Explanation: Implement duplicate or backup systems, servers, and network equipment, enabling seamless transition to secondary infrastructure if the primary system fails.
   • Example: An e-commerce platform mirrors its primary data center with a secondary one, ensuring that, in case of failure, the backup center can handle all customer transactions.
3. Automating Failover Systems
   • Explanation: Utilize automated failover mechanisms to switch operations seamlessly to backup systems, minimizing downtime and service impact during disruptions.
   • Example: A healthcare provider’s patient database has an automated failover to a redundant system, guaranteeing real-time access to patient records even if the main server experiences issues.
4. Testing Redundant Systems Regularly
   • Explanation: Schedule periodic tests of redundant infrastructure to ensure smooth operations in case of actual downtime or incidents.
   • Example: A government agency conducts bi-annual failover tests for its redundant data centers, validating that backup facilities can handle full operational loads.
5. Geographically Diverse Backup Locations
   • Explanation: Where feasible, locate redundant processing facilities in different geographical areas, reducing the risk of disruption due to localized disasters.
   • Example: An IT service provider sets up primary and backup data centers in different regions, ensuring continuity of operations even in the event of a regional power outage or natural disaster.
6. Monitoring and Maintaining Redundant Systems
   • Explanation: Continuously monitor redundant systems to ensure they remain operational and maintain regular updates for compatibility with the primary systems.
   • Example: A logistics company monitors both primary and secondary data processing facilities, verifying that backup systems stay updated with real-time data.

Conclusion

Implementing redundancy for information processing facilities is essential for organizations seeking to enhance resilience and maintain service continuity, even during disruptions. ISO 27001’s focus on redundancy underscores the value of proactive planning in safeguarding essential operations.
