Chapter: Security And Disaster Recovery
Disaster Recovery (DR) is the strategic process of preparing for, responding to, and recovering from disruptive events—whether natural disasters, cyberattacks, hardware failures, or human error. An effective DR plan ensures business continuity by minimizing downtime, preventing data loss, and preserving operations during and after a crisis.
Disaster recovery is a cornerstone of Business Continuity Planning (BCP) and is often mandated by compliance standards such as HIPAA, ISO 22301, PCI-DSS, and SOX.
1. Site Types in Disaster Recovery
Disaster Recovery (DR) sites are alternate locations or infrastructures designated to restore IT operations in the event of a major failure or catastrophe at the primary site. These sites are a crucial part of any Business Continuity Plan (BCP) and are selected based on Recovery Time Objective (RTO) and Recovery Point Objective (RPO) needs, budget, system criticality, and regulatory requirements.
