Zorluk: ZorRisk Identification, Assessment, and Response Strategies

An enterprise risk manager is evaluating proposed risk responses for a legacy payment processing database with an Asset Value (AVAV) of $500,000\$500,000. A quantitative risk assessment established an Exposure Factor (EFEF) of 0.600.60 and an Annual Rate of Occurrence (AROARO) of 0.200.20. To address the identified vulnerabilities, the leadership team executes two initiatives:

1. Decommissioning the legacy database completely and migrating its functionality to a managed SaaS platform to remove internal system exposure.
2. Executing a contract with an external service vendor that includes explicit financial indemnification clauses in the event of data breaches during transit.

Which TWO of the following statements accurately characterize these risk management responses and associated metrics?

  1. Decommissioning the legacy database represents Risk Avoidance by completely removing internal exposure to the legacy system vulnerabilities.Cevap
  2. Establishing contractual financial indemnification clauses with the external vendor represents Risk Transference.Cevap
  3. C
    The pre-initiative Annual Loss Expectancy (ALEALE) for the legacy payment processing database was $100,000\$100,000.
  4. D
    Decommissioning the legacy database functions as a deterrent security control by discouraging threat actors from targeting the organization.

Cevap

Decommissioning the database represents Risk Avoidance, and establishing financial indemnification clauses with the provider represents Risk Transference.
Risk Avoidance entails completely discontinuing an activity or retiring an asset to eliminate exposure to a threat. Risk Transference involves sharing or shifting financial risk liabilities to a third party through insurance, SLAs, or indemnification contracts. Calculating quantitative risk yields SLE=$500,000×0.60=$300,000SLE = \$500,000 \times 0.60 = \$300,000 and ALE=$300,000×0.20=$60,000ALE = \$300,000 \times 0.20 = \$60,000.

Adım Adım Çözüm

1
Calculate the Single Loss Expectancy (SLE)
SLE = AV * EF = 500,000∗0.60=500,000 * 0.60 = 300,000
Single Loss Expectancy determines the monetary loss expected every time a risk event occurs.
2
Calculate the pre-initiative Annual Loss Expectancy (ALE)
ALE = SLE * ARO = 300,000∗0.20=300,000 * 0.20 = 60,000
Annual Loss Expectancy incorporates the occurrence frequency to determine annual loss.
3
Analyze the risk response strategy for system decommissioning
Risk Avoidance
Completely eliminating the activity, process, or asset removes the vulnerability and associated risk surface.
4
Analyze the risk response strategy for vendor indemnification clauses
Risk Transference
Passing legal or financial liability to a third party transfers risk impact.
