(ISC)2 Certified in Cybersecurity Practice Exam

When does SPOF Analysis typically conclude?

1. When the system is upgraded

2. When the cost of addressing risks outweighs the benefit

3. At the end of each business quarter

4. After every major incident

The correct answer is: When the cost of addressing risks outweighs the benefit

Single Point of Failure (SPOF) Analysis is a critical component of risk management in cybersecurity and IT infrastructure. This analysis often concludes when the cost of addressing identified risks outweighs the benefits of doing so. In practice, organizations must assess and prioritize risks based on their potential impact versus the resources required to mitigate those risks. This includes evaluating finances, time, and technical capabilities. When the expense associated with implementing a solution exceeds the value or benefit the solution provides—such as enhanced system reliability or reduced downtime—organizations may decide to accept the risk rather than pursue further mitigation efforts. This decision reflects a pragmatic approach to resource allocation, balancing security needs with business realities. The other choices do not accurately capture the typical conclusion of SPOF analysis. While systems may be upgraded, or major incidents may prompt reviews of risks, these actions do not inherently signal the end of SPOF analysis. Similarly, concluding the analysis at the end of each business quarter may impose arbitrary timelines that do not align with actual risk assessment needs or business conditions. Thus, the conclusion is most aptly defined by the cost-benefit consideration of addressing risks.
