Fuzz testing is a technique where malformed inputs are sent to an application in hopes of triggering anomalous behavior. Anomalous behavior is usually a sign of an underlying vulnerability -- typically a zero-day. Fuzzing is a proven technique that maximizes defect detection with the least amount of time and resources. As a result, it not only buys organizations time and money, it also frees scarce technical resources from manual, mundane tasks and allows them to focus on strategic initiatives that require true expertise.
This framework is a model for framing the way you evaluate the economic return of investing in fuzz testing or other comparable solutions. Organizations can also use this framework to help predict which fuzz testing solutions will offer the most value based on organizational needs.
