Welcome to the OWASP Top Ten Project - if you're looking for the OWASP Top 10 Mobile Click Here
On June 12, 2013 the OWASP Top 10 for 2013 was officially released. This version was updated based on numerous comments received during the comment period after the release candidate was released in Feb. 2013.
- OWASP Top 10 2013 document (PDF).
- OWASP Top 10 2013 - Wiki.
- OWASP Top 10 2013 - French (PDF).
- OWASP Top 10 2013 - Chinese (PDF).
The OWASP Top 10 - 2013 is as follows:
- A1 Injection
- A2 Broken Authentication and Session Management
- A3 Cross-Site Scripting (XSS)
- A4 Insecure Direct Object References
- A5 Security Misconfiguration
- A6 Sensitive Data Exposure
- A7 Missing Function Level Access Control
- A8 Cross-Site Request Forgery (CSRF)
- A9 Using Components with Known Vulnerabilities
- A10 Unvalidated Redirects and Forwards
If you are interested, the methodology for how the Top 10 is produced is now documented here: OWASP Top 10 Development Methodology
Please help us make sure every developer in the ENTIRE WORLD knows about the OWASP Top 10 by helping to spread the word!!!
As you help us spread the word, please emphasize:
- OWASP is reaching out to developers, not just the application security community
- The Top 10 is about managing risk, not just avoiding vulnerabilities
- To manage these risks, organizations need an application risk management program, not just awareness training, app testing, and remediation
We need to encourage organizations to get off the penetrate and patch mentality. As Jeff Williams said in his 2009 OWASP AppSec DC Keynote: “we’ll never hack our way secure – it’s going to take a culture change” for organizations to properly address application security.
The OWASP Top Ten provides a powerful awareness document for web application security. The OWASP Top Ten represents a broad consensus about what the most critical web application security flaws are. Project members include a variety of security experts from around the world who have shared their expertise to produce this list. Versions of the 2007 and 2010 version were translated into English, French, Spanish, Japanese, Korean and Turkish and other languages. Translation efforts for the 2013 version are underway and they will be posted as they become available.
We urge all companies to adopt this awareness document within their organization and start the process of ensuring that their web applications do not contain these flaws. Adopting the OWASP Top Ten is perhaps the most effective first step towards changing the software development culture within your organization into one that produces secure code.
Changes between 2010 and 2013 Editions
The OWASP Top 10 - 2013 includes the following changes as compared to the 2010 edition:
- A1 Injection
- A2 Broken Authentication and Session Management (was formerly 2010-A3)
- A3 Cross-Site Scripting (XSS) (was formerly 2010-A2)
- A4 Insecure Direct Object References
- A5 Security Misconfiguration (was formerly 2010-A6)
- A6 Sensitive Data Exposure (2010-A7 Insecure Cryptographic Storage and 2010-A9 Insufficient Transport Layer Protection were merged to form 2013-A6)
- A7 Missing Function Level Access Control (renamed/broadened from 2010-A8 Failure to Restrict URL Access)
- A8 Cross-Site Request Forgery (CSRF) (was formerly 2010-A5)
- A9 Using Components with Known Vulnerabilities (new but was part of 2010-A6 – Security Misconfiguration)

Warning: these articles have not been rated for accuracy by OWASP. Product companies should be extremely careful about claiming to "cover" or "ensure compliance" with the OWASP Top 10. The current state-of-the-art for automated detection (scanners and static analysis) and prevention (waf) is nowhere near sufficient to claim adequate coverage of the issues in the Top 10. Nevertheless, using the Top 10 as a simple way to communicate security to end users is effective.
- as a way to measure the coverage of their SDL and improve security
- in their developer guidance on web application security
- PCI Council
- as part of the Payment Card Industry Data Security Standard (PCI DSS)
- in a guide showing how to configure their NetScalar product
- to show how "T10 threats are handled by the security design and test procedures of Microsoft"
- to demonstrate the security of this Python web framework
- for developer awareness
- to show how their product is secure for web use
- as a way to explain the coverage of their service
- to show the coverage of the SecureSphere tool
- to enable "focused scans for compliance testing with the updated PCI standard"
Users and Adopters
The U.S. Federal Trade Commission strongly recommends that all companies use the OWASP Top Ten and ensure that their partners do the same. In addition, the U.S. Defense Information Systems Agency (DISA) has listed the OWASP Top Ten as key best practices that should be used as part of the DoD Information Assurance Certification and Accreditation Process (DIACAP).
In the commercial market, the Payment Card Industry (PCI) standard has adopted the OWASP Top Ten, and requires (among other things) that all merchants get a security code review for all their custom code. In addition, a broad range of companies and agencies around the globe are also using the OWASP Top Ten, including:
- A.G. Edwards
- Bank of Newport
- Best Software
- British Telecom
