A security analyst is reviewing business continuity and resilience planning metrics following a Business Impact Analysis (BIA) for a critical enterprise application. Match each business continuity metric on the left with its corresponding operational definition on the right.
- Maximum Tolerable Downtime (MTD)The overall maximum timeframe an enterprise business process can be offline before incurring irreversible harm.
- Recovery Time Objective (RTO)The target duration of time dedicated to technical restoration of system infrastructure and applications.
- Recovery Point Objective (RPO)The maximum acceptable amount of transactional data loss measured in duration prior to a disruption.
- Work Recovery Time (WRT)The operational phase after technical recovery dedicated to data validation, application testing, and process integration.
Cevap
Maximum Tolerable Downtime (MTD) matches the overall maximum timeframe an enterprise business process can be offline before incurring irreversible harm; Recovery Time Objective (RTO) matches the target duration of time dedicated to technical restoration of system infrastructure and applications; Recovery Point Objective (RPO) matches the maximum acceptable amount of transactional data loss measured in duration prior to a disruption; Work Recovery Time (WRT) matches the operational phase after technical recovery dedicated to data validation, application testing, and process integration.
Each business continuity metric measures a distinct component of risk and recovery: Maximum Tolerable Downtime defines the fatal operational threshold, Recovery Time Objective specifies technical system recovery speed, Recovery Point Objective establishes acceptable data loss windows, and Work Recovery Time accounts for business validation prior to resuming full operations.
