CompTIA Security+ Certification SY0-601: The Total Course - Quantitative Risk Assessments

The video tutorial explains quantitative risk assessment, focusing on asset value, exposure factor, and how to calculate single loss expectancy (SLE) and annualized loss expectancy (ALE). It provides examples, particularly for an ecommerce website, to illustrate the calculations and their importance in determining the cost-effectiveness of security measures.

Why is it important to align security budgets with asset values?

• To increase the asset value

• To ensure maximum security spending

• To avoid overspending on low-value assets

• To reduce the asset's exposure factor

What does the exposure factor represent in risk assessment?

• The total value of an asset

• The percentage of an asset lost during an incident

• The annual rate of occurrence

• The cost of security controls

How is the single loss expectancy (SLE) calculated?

• By dividing asset value by exposure factor

• By subtracting exposure factor from asset value

• By multiplying asset value with exposure factor

• By adding asset value and exposure factor

In the ecommerce website example, what is the exposure factor if the site is down for 3 hours?

• 25%

• 50%

• 100%

• 12.5%

What is the purpose of calculating the annualized loss expectancy (ALE)?

• To find the single loss expectancy

• To compare with security spending

• To calculate the exposure factor

• To determine the total asset value

How is the annualized loss expectancy (ALE) determined?

• By multiplying SLE with annual rate of occurrence

• By subtracting annual rate of occurrence from SLE

• By dividing SLE by annual rate of occurrence

• By adding SLE and annual rate of occurrence

If the annual rate of occurrence is 2, and the SLE is $3000, what is the ALE?

• $6000

• $3000

• $12000

• $9000
