I must respectfully disagree with those in the security metrics field who discount nonquantitative metrics out of hand. I find it ironic that the evidence presented against qualitative measurement is itself qualitative. It is ironic because the argument itself shows how people use empirical data: raw facts or numbers do us little good. Chapter 2: Designing Effective Security Metrics Instead, we engage evidence so that we can interpret it, and it is the interpretation of the data rather than the data itself that provides us value.

TCO can help you to understand how much a security product will cost over its lifetime, but that doesn’t tell you whether or not it will meet your security needs. Chapter 1: What Is a Security Metric? Security TCO cannot escape the data uncertainties of other common metrics. Since the security world can’t agree on how to track or measure the impact of security incidents, many costs remain hidden and unavailable for inclusion in the analysis. TCO, like ROI, has also been co-opted by security vendors that recognize it as a purchasing decision support metric.

Business decision-makers tend not to like the inputs to those decisions expressed so categorically; they want to see numbers, to know how much hotter or colder, better or worse, or higher or lower something is. Numbers add a sense of certainty and importance to observations, whether or not they actually provide those things. Luckily, when a risk analysis is conducted for someone who is expecting to base decisions on numbers, a simple solution is at hand: Just change all the levels to numbers! Now a high likelihood is a 3, a medium likelihood is a 2, and a low likelihood is a 1.
