Having access to the subsystem internals in general makes the subsystem easier to understand, but also easier tohack; for example, if a programmer can examine source code, weaknesses in an algorithm are much easier to discover.[citation needed] That makeswhite-box testing much more effective thanblack-box testing but considerably more difficult from the sophistication needed on the part of the tester to understand the subsystem.
The notion of a "Black Box in a Glass Box" was originally used as a metaphor for teaching complex topics to computing novices.[6]
