As a software developer, you have a lot to worry about when writing and testing your code. But if you faithfully use secure coding guidelines from the Open Web Application Security Project (OWASP), test your code with security tools, and conduct peer code reviews, then your application will be secure, giving you worry-free sleep at night.
Wrong.
OK, sorry about that. I put that trap there for you, but I didn’t really expect you to step into it. I want to help you expand your thinking about application security.
