ANSWER-It is entitled Contingency Planning Guide for Information Technology
Systems—thus it is clearly related to business continuity and disaster recovery.

Business Impact Analysis (BIA) - ANSWER-An analysis of how specific incidents
might impact the business operations.

U.S. National Fire Protection Association (NFPA) 1600 Standard - ANSWER-This
is formally titled Standard on Disaster/Emergency Management and Business
Continuity Programs focused on responding to fire-related incidents.

Maximum Tolerable Downtime (MTD) - ANSWER-The length of time a system
can be down before the business cannot recover.

Mean Time to Repair (MTTR) - ANSWER-The average time needed to repair a
given piece of equipment.

Mean time to failure (MTTF) - ANSWER-How long, on average, before a given
piece of equipment will fail through normal use.

,Recovery Point Objective (RPO) - ANSWER-The amount of work that might need
to be redone, or data lost.

Recovery Time Objective (RTO) - ANSWER-The time that the system is

Single Loss Expectancy (SLE) formula - ANSWER-Asset Value (AV) x Exposure
Factor (EF)

Annualized Loss Expectancy (ALE) - ANSWER-Expected monetary loss for an
asset due to a risk over a one-year period calculated by multiplying single loss
expectancy by annualized rate of occurrence.

Annualized Loss Expectancy (ALE) formula - ANSWER-Single Loss Expectancy
(SLE) * Annual Rate of Occurrence (ARO)

and effects analysis (FMEA) in engineering and are sometimes called "fish

full backup - ANSWER-Backup that copies all data from a system.

differential backup - ANSWER-All changes since the last full backup

incremental backup - ANSWER-Backup that copies only the changed data since

Detection step - ANSWER-1st step in incident response

Containment step - ANSWER-2nd step in incident response

Eradication step - ANSWER-3rd step in incident response

Recovery step - ANSWER-4th step in incident response
