All models are wrong, but some models are useful. Problems can arise when you measure your progress against the abstract perfection that’s inherent in the model you are using.This book uses a generic approach to gaining or improving employment within the information security industry. It will work in some environments, but will fail (sometimes spectacularly) in others. In general, though, working from a solid model will help you to identify and overcome barriers you may experience in the working world. Deal with barriers to the job you want by pushing through them or by subverting them within the system. Different barriers require different approaches.
