Madhuri’s web application converts numbers that are input into fields by specifically typing them and then applies strict exception handling. It also sets a minimum and maximum length for the inputs that it allows and uses predefined arrays of allowed values for inputs like months or dates. What term describes the actions that Madhuri’s application is performing?

The application includes input validation techniques that are used to ensure that unexpected or malicious input does not cause problems with the application. Input validation techniques will strip out control characters, validate data, and perform a variety of other actions to clean input before it is processed by the application or stored for future use. This validation may help prevent buffer overflows, but other techniques described here are not used for buffer overflow prevention. String injection is actually something this helps to prevent, and schema validation looks at data to ensure that requests match a schema, but again this is a narrower description than the broad range of input validation occurring in the description.
