NOTE: THIS IS NOT THE LATEST VERSION. Please visit the OWASP Top 10 project page to find the latest edition.

Insecure software is already undermining our financial, healthcare, defense, energy, and other critical infrastructure. As our digital infrastructure gets increasingly complex and interconnected, the difficulty of achieving application security increases exponentially. We can no longer afford to tolerate relatively simple security problems like those presented in the OWASP Top 10.

The goal of the Top 10 project is to raise awareness about application security by identifying some of the most critical risks facing organizations. The Top 10 project is referenced by many standards, books, tools, and organizations, including MITRE, PCI DSS, DISA, FTC, and many more. This release of the OWASP Top 10 marks this project’s eighth year of raising awareness of the importance of application security risks. The OWASP Top 10 was first released in 2003, minor updates were made in 2004 and 2007, and this is the 2010 release.

We encourage you to use the Top 10 to get your organization started with application security. Developers can learn from the mistakes of other organizations. Executives should start thinking about how to manage the risk that software applications create in their enterprise.

But the Top 10 is not an application security program. Going forward, OWASP recommends that organizations establish a strong foundation of training, standards, and tools that makes secure coding possible. On top of that foundation, organizations should integrate security into their development, verification, and maintenance processes. Management can use the data generated by these activities to manage cost and risk associated with application security.

We hope that the OWASP Top 10 is useful to your application security efforts. Please don’t hesitate to contact OWASP with your questions, comments, and ideas, either publicly to [email protected] or privately to [email protected].

Welcome to the OWASP Top 10 2010! This significant update presents a more concise, risk focused list of the Top 10 Most Critical Web Application Security Risks. The OWASP Top 10 has always been about risk, but this update makes this much more clear than previous editions. It also provides additional information on how to assess these risks for your applications.

For each item in the top 10, this release discusses the general likelihood and consequence factors that are used to categorize the typical severity of the risk. It then presents guidance on how to verify whether you have problems in this area, how to avoid them, some example flaws, and pointers to links with more information.

The primary aim of the OWASP Top 10 is to educate developers, designers, architects, managers, and organizations about the consequences of the most important web application security weaknesses. The Top 10 provides basic techniques to protect against these high risk problem areas – and also provides guidance on where to go from here.

Don’t stop at 10. There are hundreds of issues that could affect the overall security of a web application as discussed in the OWASP Developer's Guide. This is essential reading for anyone developing web applications today. Guidance on how to effectively find vulnerabilities in web applications are provided in the OWASP Testing Guide and the OWASP Code Review Guide, which have both been significantly updated since the previous release of the OWASP Top 10.

Constant change. This Top 10 will continue to change. Even without changing a single line of your application’s code, you may already be vulnerable to something nobody ever thought of before. Please review the advice at the end of the Top 10 in “What’s Next For Developers, Verifiers, and Organizations” for more information.

Think positive. When you’re ready to stop chasing vulnerabilities and focus on establishing strong application security controls, OWASP has just produced the Application Security Verification Standard (ASVS) as a guide to organizations and application reviewers on what to verify. Use tools wisely. Security vulnerabilities can be quite complex and buried in mountains of code. In virtually all cases, the most cost-effective approach for finding and eliminating these weaknesses is human experts armed with good tools.

Push left. Secure web applications are only possible when a secure software development life-cycle is used. For guidance on how to implement a secure SDLC, we recently released the Open Software Assurance Maturity Model (SAMM), which is a major update to the OWASP CLASP Project.
