Question 243 - CISM discussion

The fundamental purpose of establishing security metrics is to provide feedback on the effectiveness of the information security controls and processes. Security metrics are quantitative or qualitative measures that indicate how well the organization is achieving its security objectives and goals. Security metrics can help the information security manager to monitor, evaluate, and improve the performance of the information security program, as well as to identify gaps, weaknesses, and areas for improvement. Security metrics can also help the organization to demonstrate compliance with internal and external standards, regulations, and best practices.Increasing return on investment (ROI), adopting security best practices, and establishing security benchmarks are possible outcomes or benefits of using security metrics, but they are not the fundamental purpose of establishing them.Reference= CISM Review Manual, 16th Edition, pages 46-471; CISM Review Questions, Answers & Explanations Manual, 10th Edition, page 642
