One approach to detecting these vulnerabilities is fuzz testing. Software can also be used to simulate medical processes and protocols to measure cost effectiveness and resource utilization. In the absence of sufficient real-world data, creating suitably large data sets for testing can be a difficult task. However, typical fuzz testing makes no guarantees regarding the syntactic and semantic validity of the input,... For large, complex software systems, it is typically impossible in terms of time and cost to reliably test the application in all possible execution states and configurations before releasing it into production.
