post-disaster recovery management

A structured approach within Business Continuity Management (BCM) to resume, recover, and restore operations to a pre-defined level after a disruption. Governed by ISO 22301, it focuses on achieving Recovery Time Objectives (RTOs) and Recovery Point Objectives (RPOs) identified through a Business Impact Analysis (BIA). Unlike immediate emergency response, recovery management is a planned process encompassing not just IT systems (as per ISO/IEC 27031), but also personnel, facilities, and supply chains. It is a critical reactive control that operationalizes an organization's resilience strategy, ensuring a timely and orderly return to business as usual.

Implementation involves three key steps. First, establish a recovery plan based on a Business Impact Analysis (BIA), defining roles, responsibilities, and procedures as required by ISO 22301 Clause 8.4. Second, prepare resources, such as backup sites and data, and conduct regular drills (e.g., tabletop, functional tests) to validate the plan's effectiveness, following guidance from NIST SP 800-84. Third, execute the plan during an incident and conduct a post-incident review for continuous improvement. A Taiwanese financial firm applied this, recovering its core systems in under 2 hours during a power outage, preventing millions in losses and achieving a 100% audit pass rate.

Taiwan enterprises face three main challenges. 1) Limited resources in SMEs for dedicated disaster recovery sites. Solution: Adopt cloud-based Disaster Recovery as a Service (DRaaS) to shift from CapEx to OpEx and cross-train existing staff. 2) Highly concentrated supply chains, especially in tech parks. Solution: Diversify suppliers and assess their BCM capabilities, guided by ISO 22318. 3) Lack of a robust testing culture, viewing recovery as solely an IT issue. Solution: Secure top management buy-in, integrate BCM drills into performance KPIs, and conduct mandatory annual exercises to foster a resilient culture.
