Website security for developers made easy. This book covers the most common ways websites get hacked and how web developers can defend themselves.

The world has changed. Today, every time you make a site live, you’re opening it up to attack.

A first-time developer can easily be discouraged by the difficulties involved with properly securing a website. But have hope: an army of security researchers is out there discovering, documenting, and fixing security flaws. Thankfully, the tools you’ll need to secure your site are freely available and generally easy to use.

Web Security for Developers will teach you how your websites are vulnerable to attack and how to protect them. Each chapter breaks down a major security vulnerability and explores a real-world attack, coupled with plenty of code to show you both the vulnerability and the fix.

You’ll learn how to:
•  Protect against SQL injection attacks, malicious JavaScript, and cross-site request forgery
•  Add authentication and shape access control to protect accounts
•  Lock down user accounts to prevent attacks that rely on guessing passwords, stealing sessions,
•  or escalating privileges
•  Implement encryption
•  Manage vulnerabilities in legacy code
•  Prevent information leaks that disclose vulnerabilities
•  Mitigate advanced attacks like malvertising and denial-of-service

As you get stronger at identifying and fixing vulnerabilities, you’ll learn to deploy disciplined, secure code and become a better programmer along the way.
