Welcome to the OWASP Cheat Sheet Series

Welcome to the official repository for the Open Worldwide Application Security Project® (OWASP) Cheat Sheet Series project. The project focuses on providing good security practices for builders in order to secure their applications.

In order to read the cheat sheets and reference them, use the project official website. The project details can be viewed on the OWASP main website without the cheat sheets.
