3 Implementing a security metrics program

 

This chapter covers

  • Designing a cybersecurity metrics program
  • Building effective metrics dashboards
  • Exploring open-source tools
  • Analyzing and reporting to drive actionable decisions
  • Common challenges and pitfalls and how to avoid them

Implementing an information security program is more than simply setting up defenses, checking boxes, and relaxing. Organizations must continuously evaluate the effectiveness of security measures. Having data-driven insights and the ability to measure and analyze that data is the best way to make better, more informed decisions. The metrics we have discussed throughout this book allow us to measure the performance of our information security program. We can identify weaknesses, optimize our defenses, and report to the C-level on our standing.

In this chapter, we will discuss the importance of a well-designed cybersecurity metrics program. I will provide you with a repeatable and proven process using the METRICS methodology. This methodology is a comprehensive guide for measuring and evaluating security performance to better align our efforts with business goals. This chapter will provide the framework for building a sustainable, scalable metrics program.
