The OWASP Top 10 Web Application Security Risks for 2010 are:

A1: Injection

A3: Broken Authentication and Session Management

A5: Cross-Site Request Forgery (CSRF)
A6: Security Misconfiguration

Please help us make sure every developer in the ENTIRE WORLD knows about the OWASP Top 10 by helping to spread the world!!!

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.

If you are interested in doing a presentation on the OWASP Top 10, please feel free to use all or parts of this: OWASP Top 10 - 2010 Presentation

Introduction

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 were translated into English, French, Spanish, Japanese, Korean and Turkish and other languages. Translation efforts for the 2010 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.
