Changes to OWASP Top 10 for 2021 – Web Application Security Training updated

The Open Web Application Security Project (OWASP) has made changes to the OWASP Top 10 for 2021. OWASP is an open community dedicated to enabling organizations to develop, purchase, and maintain applications and APIs that can be trusted.

Since 2003, the OWASP Top 10 has become a world-renowned reference document that details the most critical security risks to web applications. These help organizations and developers to develop secure applications. The Top 10 is a baseline for compliance, education, and vendor tools.

Changes to the OWASP Top 10 for 2021

The Top 10 includes three new categories. Of these, four have seen changes to their names or scope. Furthermore, others have been consolidated to focus on the root cause over the symptom.
