OWASP Practice is a virtual environment to help people who want to begin their journey into web appplication security. With lots of material including videos available on internet both for free and paid teach web application security in a good manner. But this project has been started for the sole purpose of helping people to understand the basics behind a vulnerability and gradullay moving forward. OWASP Practice contains a learning environment which helps to understand why and how a vulnerability triggers. This project or any other project alone cannot help anyone master everything. It just our contribuition to the community. We were a beginner in this field at some point of time and still we are in a continuous learning phase. We hope this project helps the community.
Coming back to "OWASP Practice". OWASP releases a list of top 10 vulnerabilities. "OWASP Top 10 Web Application Vulnerabilities" is one of the most popular projects by OWASP. The project starts with explaining every vulnerability in as easy words as possible along with vulnerable demo applications and videos demonstrating the vulnerability in action.
