OWASP Top 10 2017 Released
The [[Media:OWASP_Top_10-2017_(en).pdf.pdf| OWASP Top 10 - 2017]] is now available.

OWASP Top 10 Most Critical Web Application Security Risks
The OWASP Top 10 is a powerful awareness document for web application security. It represents a broad consensus about the most critical security risks to web applications. Project members include a variety of security experts from around the world who have shared their expertise to produce this list.

We urge all companies to adopt this awareness document within their organization and start the process of ensuring that their web applications minimize these risks. Adopting the OWASP Top 10 is perhaps the most effective first step towards changing the software development culture within your organization into one that produces secure code.

Translation Efforts
The OWASP Top 10 has been translated to many different languages by numerous volunteers. These translations are available as follows:


 * OWASP Top 10 - 2017 translations are currently underway

= OWASP Top 10 for 2013 =



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 Presentation - Presenting Each Item in the Top 10 (PPTX).

For 2013, the OWASP Top 10 Most Critical Web Application Security Risks are:


 * 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.

Introduction
The OWASP Top 10 is a powerful awareness document for web application security. It represents a broad consensus about the most critical security risks to web applications. 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. The 2013 version was translated into even more languages.

We urge all companies to adopt this awareness document within their organization and start the process of ensuring that their web applications minimize these risks. Adopting the OWASP Top 10 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)
 * A10 Unvalidated Redirects and Forwards

= Some Commercial & OWASP Uses of the Top 10 =



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.


 * Microsoft
 * as a way to measure the coverage of their SDL and improve security


 * PCI Council
 * as part of the Payment Card Industry Data Security Standard (PCI DSS)


 * Microsoft
 * to show how "T10 threats are handled by the security design and test procedures of Microsoft"


 * OWASP
 * OWASP Top 10 Mapped to the Web Hacking Incident Database
