Top 10 2013

= TEMPORARY PLACEHOLDER for 2013 T10 =

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.
