Fuzzing

In computer security parlance, fuzzing is the art of automatic bug finding. This is done by providing an application with semi-valid input. The input should in most cases be good enough so applications will assume it's valid input, but at the same time be broken enough so that parsing done on this input will fail. Fuzzing is mostly used to uncover security bugs.

It's a style of haircut that made wearing a police hat more comfortable and cooler to wear......still in vogue today and used by many police officers around the world.
