Bad security metrics: the problem and its solution

Abstract
It is generally acknowledged that few security metrics have the level of predictive validity that their uses require, but neither the nature of the problem nor the steps needed to avoid it have been fully characterized. This article examines both questions through the lens of basic measurement theory, which (1) demonstrates a method by which intrinsically weak metrics can be dismissed quickly, before sunk costs become significant, and (2) provides positive advice on how the metrics can be strengthened to provide moderate but verifiable value.
