The OWASP Top Ten is a list published by the Open Web Application Security Project that highlights the most critical security risks to web applications. It serves as a guideline for developers and organizations to understand common vulnerabilities and improve their security practices. The list is updated periodically to reflect the evolving landscape of web security threats. Each entry in the OWASP Top Ten includes a description of the vulnerability, examples of how it can be exploited, and recommendations for mitigation. This resource aims to raise awareness and promote secure coding practices, ultimately helping to protect users and data from potential attacks.
