Risk Reduction

Overview

Risk reduction is a broad treatment objective achieved through preventive, detective, corrective, recovery, or diversification measures. It can target the source of risk, interrupt the event path, protect affected assets, or improve resilience after impact.

Reduction should be measured against a baseline and may be partial. Controls can decay, cover only selected assets, depend on other systems, or transfer harm to customers, vendors, or different parts of the organization.

Plans should specify target exposure, control changes, evidence, cost, owner, implementation date, and residual risk. Validation must test real operation and stressed conditions, while monitoring identifies whether business growth or threat change has offset the expected benefit.

Risk Reduction is a measurable uncertainty or exposure that lowers exposure by decreasing the probability, consequence, duration, concentration, or uncertainty of a defined adverse scenario. Risk reduction requires measurable improvement in a defined scenario, supported by operating evidence and reassessment of residual and secondary exposure.

For Risk Reduction, the assessment should evaluate a measurable uncertainty or exposure that lowers exposure by decreasing the probability, consequence, duration, concentration, or uncertainty of a defined adverse scenario. The assessment record should separate observed evidence supporting a measurable uncertainty or exposure that lowers exposure by decreasing the probability, consequence, duration, concentration, or uncertainty of a defined adverse scenario from assumptions, state the time horizon and existing controls, and identify who owns any remaining exposure. Monitoring should test whether the conditions described in a measurable uncertainty or exposure that lowers exposure by decreasing the probability, consequence, duration, concentration, or uncertainty of a defined adverse scenario have changed enough to require a new rating, treatment, or approval.
