WGU Digital Forensics in Cybersecurity - C840 Business Continuity Plan (BCP) - ANSWER A plan for maintaining minimal operations until the business can return to full normal operations.Disaster Recovery Plan (DRP) - ANSWER A plan for returning the business to full normal operations.International Organization for Standardization (ISO) 27001 standard - ANSWER It is a code of practice for implementing an information security management system, against which organizations can be certified.National Institute of Standards and Technology (NIST) 800-34 standard - ANSWER It is entitled Contingency Planning Guide for Information Technology Systems—thus it is clearly related to business continuity and disaster recovery. 1 / 4
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. 2 / 4
Recovery Time Objective (RTO) - ANSWER The time that the system is expected to be back up. This must be less than MTD.Single Loss Expectancy (SLE) - ANSWER The expected monetary loss every time a risk occurs.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) Annual Rate of Occurrence (ARO) - ANSWER The number of times an incident is expected to occur in a year Damage Potential, Reproducibility, Exploitability, Affected Users, and Discoverability (DREAD) - ANSWER It is a 3 / 4
mnemonic for risk rating using five categories and an effective model for evaluating the impact of an attack.Remote Network MONitoring (RMON) - ANSWER Developed by the Internet Engineering Task Force (IETF) in order to support network monitoring and protocol analysis.Mean squared deviation (MSD) formula - ANSWER It is relatively simple and provides insight into how any system deviates from expectations. This is sometimes referred to as the mean squared error.Mean percentage error (MPE) formula - ANSWER It is the arithmetic mean of errors from modeling. This metric compares expected values to actual values and calculates mean error.Ishikawa diagrams - ANSWER Commonly used engineering tool in failure mode and effects analysis (FMEA) in engineering and are sometimes called "fish diagrams" full backup - ANSWER Backup that copies all data from a system.
