About the Book
Do you ever wonder how vulnerable you are to being hacked? Do you feel confident about storing your users sensitive information? Imagine feeling confident in the integrity of your software when you store your user's sensitive data. No more fighting fires with lost data, no more late nights, your application is secure. In this short book I'll give you clear, actionable details on how to secure various parts of your web application. You will also find scenarios to handle and improve existing legacy issues.
Several years ago I was writing a web application for a client in the CodeIgniter PHP framework, *shudder*, but CodeIgniter didn't include any type of authentication system built in. I of course did what any good/lazy developer would do and went on the hunt for a well made library to supply authentication capabilities. To my chagrin I discovered that there weren't any clean, concise libraries that fit my needs for authentication in CodeIgniter. Thus began my journey of creating Ion Auth, a simple authentication library for CodeIgniter, and a career long crusade for securing web applications as well as helping other developers do the same.
Here we are years later, a lot of us have moved on to other frameworks or languages, but I still repeatedly see basic security being overlooked. So let's fix that. I want to make sure that you'll never have to live the horror of leaking user passwords, or have someone inject malicious SQL into your database, or the suite of other "hacks" that could have been easily avoided. Let's make sure we all get home on time and sleep well at night.
