Definition
  • Natural Hazards earthquakes, tornados, etc
  • Human-caused accidental/intentional. accidental file deletion; vandalism, theft, fraud.
  • Technology-caused HW/SW malfunction; not obvious
Term
Business Impact Analysis (BIA)
Definition
  • BCP phase that IDs risks and impact to critical OPs if risks happen
  • vulnerability assessments/evals
  1. prioritization of crit. processes
  2. reduced effeciency
  3. estimated tolerable downtime
  4. financial loss impact
  5. resources needed to restore
Term
BIA Org. Goals (4)
Definition
  1. Ensure health/safety of staff
  2. Enable continual operations: property, infrastructure, facilities

  2. Data Collection
  3. App/Data criticality assessment
  4. Data Analysis to assess vulnerabilities, other factors
Term
Critical Business Process
Definition
  • activity, that if not recovered, will cause loss and biz failure
  • by Sr. Mgt on ACTUAL impact; not just internal policies
  • ID Key Personnel
Term
Vulnerability Assesment
Definition
  • BIA phase where financial and operational loss impact is ID'd
  • Vulnerability tables: strategic tools for completing assessment
Term
Max. Tolerable Downtime (MTD)
Definition
  • longest period of time outage may occur w/o causing serious biz failures
Term
Recovery Point Objectives (RPO)
Definition
  • point in time, where data recovery begins
  • last backup before disaster happens

 

Term
Recovery Time Objectives (RTO)
Definition
  • time it takes to restore to NORMAL business ops/activities after a disturbance
  • time to return to RPO point
  • must be achieved before MTD
Term
RPO/RTO Optimization
Definition
  • ideal 0 (immediate recovery)
  • near 0 is $$$$
  • need to determine RPO/RTO cost vs loss cost

  3. Assess Level of Impact
Term
Disaster Recovery Plan (DRP)
Definition

Term
Disaster Recovery Strategy (3 factors)
Definition
  • Risk People, Places, Things
    • People: safety of people
    • Places: relocation?
    • Things: equipment
