Welcome to the official repository for the Open Web 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's official website. The project details can be viewed on the OWASP main website without the cheat sheets.
🚩 Markdown files are the working sources and are not intended to be referenced in any external documentation, books or websites.
