Domain 08 – BCP & DRP

Business Continuity and Disaster Recovery Planning addresses the preservation of business operations in the face of major disruptions. Many candidates overlook this domain, yet results often show it is poorly understood due to lack of practical experience. This session breaks down both Business Continuity Planning (BCP) and Disaster Recovery Planning (DRP) in detail. BCP ensures an organisation can sustain critical operations through internal or external disruptions. It combines preparation, testing, and maintenance of plans to minimise the impact of systems or network failures. DRP focuses on restoring mission-critical functions after partial or total loss of IT infrastructure, ensuring return to normal operations within a defined time. Candidates must understand BCP project planning, business impact analysis (BIA), risk assessments, recovery strategies, and implementation. DRP includes emergency procedures, backup operations, and post-disaster recovery. Life safety is prioritised above all else in planning. Plans must address natural and human-caused events. Project scope planning follows industry guidelines such as BS 25999, ISO 22399, ISO 24762, and NIST SP 800-34. These define best practices in continuity management and ICT contingency planning. Organisations should also refer to frameworks from the Business Continuity Institute and the Disaster Recovery Institute International. BCM includes BCP, DRP, and incident management. BCP includes BIA, risk analysis, alternative processes, and response protocols. DRP covers disaster declaration, alternate site migration, and recovery objectives. Incident management includes containment, resolution, and root cause analysis. BCP lifecycle includes management commitment, strategy selection, plan development, testing, and updates. Management buy-in is challenging, as it often feels like selling insurance. Champions and specialists guide DRP project plans. Policies ensure continuity is enforced as corporate standard and audited accordingly. Interdependencies must be mapped to avoid domino effects. A steering committee governs scope and authorisation. Asset identification, including external dependencies and legacy systems, is vital. Virtualisation improves DR capabilities. Budget and legal requirements influence ROI. Personnel and alternate staffing are planned with contingency for absence or leave. Tools help manage large implementations. Vendor readiness is assessed. BIAs differentiate critical and non-critical functions. Recovery Point Objective (RPO) defines acceptable data loss. Recovery Time Objective (RTO) defines acceptable downtime. Critical systems are prioritised based on operational, financial, or reputational impact. Threat modelling includes sabotage, IT failures, natural disasters, supply chain disruptions, utility failure, and personnel loss. Emergency assessments define affected areas, triage needs, notification protocols, and safety procedures. All actions are documented for legal accountability. Critical functions are measured by time sensitivity, data integrity, and classification. Dependencies must be identified—upstream, downstream, and circular. Service-level agreements and compliance requirements are key for third-party impact. Recovery strategies include mirrored sites, mobile sites, hot, warm, cold sites, reciprocal agreements, and external service providers. Tiered recovery levels range from no backup to fully automated real-time systems. Backup technologies include replication, remote journaling, and electronic vaulting. Offsite storage distance is not universally defined but should avoid shared risks. Site, IT, and organisational resilience should be planned. Past events like 9/11 illustrate the importance of diversified recovery. Plans should include emergency response, event reporting, and escalation. Notification and activation procedures must be defined and include succession planning and public relations handling. Testing methods include checklists, walkthroughs, simulations, parallel testing, and full interruption tests. Post-test reviews identify deficiencies and update documentation. Change control should include DRP and backup review. Testing should occur at least annually, or when changes impact recovery capability. Recovery procedures include local and alternate site recovery, prioritisation, and data synchronisation. Certification, audit, and restoration processes follow. Decisions may designate a new primary site after loss. Procurement and asset disposal are coordinated, and insurance claims supported by cost tracking. Restoration includes system reactivation, business process recovery, and transaction reconciliation. Plan feedback loops involve gap analysis, metrics review, and training. Final steps include plan distribution, stakeholder communication, and post-mortem reviews for lessons learned and prevention.
