Abstract :
Using exams to create labels for our workforce might sound like a way to get more trustworthy systems, but it´s not. If it walks like a duck, quacks like a duck, and looks like a duck, then there´s good reason to believe that it´s a duck. But you don´t get a duck just by calling something a duck, and you don´t get trustworthy systems simply by introducing a labeling scheme for system-builders. You can´t label-in security. To have the desired effect, a credential must bestow obligations and responsibilities on practitioners.
