OWASP Top 10 Application Security Risks 2021
Explore the most critical web security risks in OWASP Top 10 2021. Learn about new categories, data-driven insights, and the impact on web applications.
The OWASP Top 10 2021 is a comprehensive list of the most critical web application security risks. This year's edition features three new categories, four renamed categories, and some consolidation of the previous Top 10. The rankings are based on contributed data from organizations and a community survey. The categories are structured to focus on root causes rather than symptoms, providing better guidance for identification and remediation. The data collection and analysis process involved collecting data from various sources and mapping CWEs to risk categories. The incidence rate was used instead of frequency to merge different types of data and provide a clearer view of vulnerabilities across multiple testing types. The resulting Top 10 list is more data-driven than ever before, providing valuable insights into the most prevalent and impactful security risks. Special thanks to the data contributors and sponsors who made this edition possible.

Significance and Impact of 2021's Top 10 Risks
The OWASP Top 10 2021 identifies the most significant and impactful security risks for web applications. Each category represents a specific vulnerability that, if exploited, can lead to severe consequences such as data breaches, unauthorized access, and system compromise. The rankings are based on incidence rates, testing coverage, and weighted exploit and impact scores. By understanding the significance and impact of these risks, developers and security professionals can prioritize their efforts to mitigate vulnerabilities and protect their applications from potential attacks. It is crucial for organizations to stay updated with the latest Top 10 risks to ensure the security and integrity of their web applications.
Regulatory Changes and Compliance
The OWASP Top 10 2021 not only helps organizations identify and address security risks but also plays a significant role in regulatory compliance. Many industry regulations and frameworks, such as PCI DSS and HIPAA, require organizations to implement measures to address common web application vulnerabilities. By aligning their security practices with the OWASP Top 10, organizations can demonstrate compliance with these regulations and ensure the protection of sensitive data. Additionally, staying compliant with the latest security standards enhances an organization's reputation, instills customer trust, and mitigates the risk of legal and financial consequences.
Future Outlook
The field of web application security is constantly evolving, and new vulnerabilities and risks continue to emerge. As technology advances, so do the threats targeting web applications. It is essential for developers, security professionals, and organizations to stay vigilant and adapt their security measures accordingly. The future outlook of web application security involves embracing emerging technologies like artificial intelligence and machine learning to enhance threat detection and response. Additionally, continued collaboration between security researchers, industry professionals, and organizations is crucial for staying one step ahead of cybercriminals and protecting web applications from evolving threats.
