ISO 24762

ISO 24762 is an international standard specifically addressing the design and implementation of Disaster Recovery Centers (DRC) as part of Business Continuity Management (BCM). It provides technical requirements for recovery site selection, infrastructure configuration, data-centric recovery strategies, and personnel response procedures. This standard complements ISO 22301 by providing the technical specifications needed to achieve the RTO (Recovery Time Objective) and RPO (Recovery Point Objective)-based targets established during the Business Impact Analysis (BIA) phase. It is particularly relevant for industries with high-availability requirements, such as finance, telecommunications, and manufacturing, where information system downtime can lead to significant financial and reputational damage. Unlike general backup-focused standards, ISO 24762 emphasizes the operational capability of the recovery environment to be fully functional within the defined recovery window.

The application of ISO 24762 follows a structured three-phase approach. Phase 1: Requirement Analysis. Based on the BIA conducted under ISO 22301, enterprises identify critical business functions and their corresponding RTO/RPO targets. This phase determines the necessary-level of DRC, such as warm site, hot site, or cloud-based recovery solutions. Phase 2: Design and Implementation. This involves the technical specification of the DRC, including network topology,-redundant power supplies, data-replication-latency-adjusted-storage-solutions, and-communication-channels. Phase 3: Validation and Maintenance. Regular disaster-recovery-drills-and-testing-are-required to ensure the DRC meets the RTO/RPO-objectives. Real-world implementation in Taiwan's financial sector has shown that enterprises following these standards can reduce recovery-time-by-up-to-50% and improve-system-availability-to-99.9% within the first year of operation.

Taiwan enterprises face three primary challenges. First, the geographical risk of earthquakes and typhoons requires a multi-site DRC strategy, which increases infrastructure costs. This can be mitigated by adopting cloud-based DR solutions that offer geo-redundancy without the need for physical site-building. Second, the complexity of local regulations, including the Taiwan Personal Data Protection Act (個資法) and sectoral-specific regulations (e.g., 金管會), requires strict data-residency-and-access-controls within the DRC design. Third, the high-cost of technology-upgrades often leads to resistance from management. The solution is to implement a phased approach, starting with the most critical systems and scaling up as the ROI-justification-is-validated through reduced-downtime-costs. Professional guidance is essential to ensure compliance and optimize the investment-to-risk-reduction ratio.
