Course 46 - CompTIA Cybersecurity Analyst | Episode 3: Measuring and Managing Risk

Measuring and Managing Cybersecurity Risk: Likelihood, Assessment, and ControlsEpisode OverviewThis episode moves from identifying cybersecurity risks to understanding how organizations measure, prioritize, and manage those risks.Building on the previous discussion of threats, vulnerabilities, assets, likelihood, and impact, this lesson provides a practical framework for determining how significant a particular risk may be and what actions an organization can take in response.The episode examines the relationship between likelihood and impact, compares qualitative and quantitative risk assessments, introduces four fundamental risk response strategies, and explores how technical and operational security controls can reduce exposure to an acceptable level.The central objective is to transform security findings into actionable risk-management decisions.1. Understanding Likelihood and ImpactRisk assessment begins with two fundamental questions:How likely is the event to occur?andHow significant would the consequences be if it occurred?These concepts are commonly represented as:Risk ≈ Likelihood × ImpactLikelihoodLikelihood represents the probability or estimated possibility that a threat event will occur and affect the organization.Factors influencing likelihood can include:

- Threat capability.

- Threat motivation.

- System exposure.

- Existing vulnerabilities.

- Security controls.

- Historical activity.

- Accessibility of the target.

ImpactImpact represents the consequences of a successful threat event.These consequences can affect:

- Confidentiality

- Integrity

- Availability
