15. A protective system is evaluated on the cost effectiveness of its individual measures in countering threats, reducing vulnerabilities, and:
Answer: B
Reducing risk exposure is a key factor in evaluating a protective system.
Cost effectiveness in a protective system involves assessing how well individual measures minimize potential risks and vulnerabilities. Reducing risk exposure is essential as it directly correlates with enhancing the overall security posture of the organization.
A) return on investment.
While return on investment (ROI) is an important financial metric, it does not specifically address the core objective of a protective system, which is to mitigate risks and vulnerabilities. ROI focuses more on financial gains rather than the effectiveness of measures in countering threats and reducing exposure.
B) decreasing risk exposure.
This option is correct as it directly relates to the primary goal of a protective system, which is to lower the likelihood or impact of potential threats. Evaluating measures based on their ability to decrease risk exposure ensures that resources are allocated toward the most effective strategies for enhancing security.
C) denying access.
Denying access is a tactic that can be employed within a protective system but does not encompass the broader evaluation of cost effectiveness. This option focuses solely on access control rather than the overall reduction of risk exposure, which is a more comprehensive measure of effectiveness.
D) increasing employee awareness.
Increasing employee awareness is an important aspect of security training, but it is not directly related to the cost effectiveness of protective measures in countering threats and reducing vulnerabilities. This option addresses a supportive element of security rather than the core evaluation of protective system measures.
Conclusion
Reducing risk exposure is the most relevant measure in assessing the cost effectiveness of a protective system, as it encompasses the primary objective of mitigating threats and vulnerabilities. Other options, while important, do not directly address the essential evaluation criteria needed to ensure security effectiveness. Thus, option B stands out as the most appropriate choice in this context.
