Essential knowledge for every web developer, discover important principles of modern web security, and learn about current security best practices. Web applications are inherently insecure, as aptly illustrated by a pile of recent events. Insecurity is however not fundamental to the web platform. As a matter of fact, the modern web offers a variety of powerful security features that help stop a hacker. Unfortunately, not many developers have the knowledge and skills to leverage these security features to their full potential.
