Original Post: How the OWASP Top 10 Vulnerabilities List Developed? | by Ajay Monga | Jul, 2024
The OWASP Top 10 is a crucial document for web application security, representing a consensus on the most critical security risks. First published in 2003, it gets updated regularly to reflect the evolving threat landscape. The initial list from 2003 included vulnerabilities like Unvalidated Input, Broken Access Control, and Cross-Site Scripting (XSS). The development of this list involves several steps:
- Data Collection and Community Input: Gathering data from security vendors, consulting firms, and other sources. For the 2021 update, data from over 50,000 applications was analyzed.
- Data Analysis and Expert Review: Security experts review and analyze the data to identify common and severe vulnerabilities.
- Feedback and Consensus Building: Drafts are shared with the OWASP community for feedback and validation.
- Prioritization: Vulnerabilities are ranked based on factors like exploitability, impact, and mitigation difficulty.
- Publication and Maintenance: The final list is published and periodically updated.
The most recent list from 2021 includes specific vulnerabilities such as Broken Access Control, Cryptographic Failures, and Server-Side Request Forgery (SSRF). The evolution of the OWASP Top 10 shows changes in web application security, highlighting new threats and practices.
