Introduction

The OWASP Developer Guide provides an introduction to security concepts and an initial reference for application and system developers.

This guide does not seek to replicate the many excellent sources on specific security topics; it rarely tries to go into detail on a subject and instead provides links for greater depth on these security topics.

The content of the Developer Guide aims to be accessible, introducing practical security concepts and providing enough detail to get developers started on various OWASP tools and documents.

The intended audience of the Developer Guide is application developers working in various domains such as web, desktop, mobile, API and cloud.

Collected here are the previous versions of the OWASP Developer Guide that can still be accessed. OWASP has a podcast on The History of the OWASP Developer Guide which discusses the history and future of the project.

In addition if you have documents for versions 0.1, 0.2 and 0.3 then it would be great to have these historical records. Please get in touch with the project leaders if you have any of these.
