Computer Security Applicationsintermediate
Compare qualitative and quantitative cybersecurity risk analysis, and explain when each can help decision-makers.
Answer
Qualitative analysis uses descriptive categories such as High, Medium, and Low to compare risks. Quantitative analysis uses numerical estimates, often informed by loss and occurrence data, to estimate costs or frequency. Qualitative analysis can support comparison when precise data are unavailable, while quantitative estimates can support financial planning when useful data exist. Neither method removes uncertainty.
Explanation
### What a good answer covers
- Defines qualitative analysis as descriptive ratings such as High, Medium, and Low.
- Defines quantitative analysis as numerical estimates based on data or costs.
- Explains that quantitative values can support financial comparisons and estimates.
- Notes that the choice depends on available evidence and the decision being made.
- Avoids treating either method as perfectly certain.
### Terms
- **Qualitative analysis**: Risk comparison using descriptive categories.
- **Quantitative analysis**: Risk analysis using numerical estimates.
### Remember
Use the method that fits the evidence and the decision.
