You can memorize the information in the rest of this book and be the most knowledgeable security expert, but the real value of that knowledge comes when it is applied to finding and securing the entry points in your application. The more you know about the entry points in your applications, the better you will be able to prioritize and target your security testing efforts. Otherwise, you might miss several vulnerabilities that a malicious attacker will not.
