CISSP-ISSAP: Information Systems Security Architecture Professional

A Business Impact Analysis (BIA) is the process used to identify and document the relationships and dependencies between mission-critical business applications, processes, and operations and all of the supporting resources (IT systems, data, personnel, facilities, and third parties) that they rely on, along with the impact of their disruption; this mapping is what subsequently drives recovery time/point objectives and continuity and disaster recovery planning priorities.
