The cost-effectiveness of the security function can be demonstrated through which approach?

• A. Auditing
• B. Cost-benefit analysis
• C. Risk assessment
• D. Benchmarking

Answer: (D)

Evaluating whether security investments deliver value comes down to putting costs and benefits into a common measure and comparing them. This is done through cost-benefit analysis, which assigns monetary values to both what you spend on security (staff, equipment, training, maintenance) and the benefits you gain (fewer incidents, reduced losses, shorter incident response times, avoidance of penalties, improved patient and staff safety). By calculating net benefit or return on investment, you can clearly see if the security program provides value beyond its cost.

Auditing checks compliance and performance against standards, but it doesn’t quantify whether the security program is worth the investment. Risk assessment identifies threats and prioritizes controls, yet it focuses on risk levels rather than translating outcomes into monetary terms. Benchmarking compares your performance to other organizations to gauge relative standing, not specifically the cost-effectiveness of the security function.
