Introduction<\/b><\/h1>\n

With the rapid growth of web applications, cyber threats have become more sophisticated than ever. Organizations must secure their applications against vulnerabilities that attackers exploit to steal sensitive data, disrupt services, or gain unauthorized access. One of the most trusted resources for improving web application security is the OWASP Top 10, a globally recognized awareness document published by the Open Worldwide Application Security Project (OWASP).<\/span><\/p>\n

Definition<\/b><\/h1>\n

OWASP Top 10<\/b> is a standard awareness document developed by the <\/span>Open Worldwide Application Security Project (OWASP)<\/b> that identifies the <\/span>ten most critical security risks affecting web applications<\/b>. It is based on real-world vulnerability data collected from security organizations and experts worldwide.<\/span><\/p>\n
