The Hardened Application: Testing Principles from OWASP

Presented at ConFoo 2015

Secure development has become a necessary part of any development process, there’s no way around that. Protecting the various parts of your application (and users) is also becoming more complex. Writing the code is only half the battle - it still needs to be tested. What tests do you need to worry about, though? Join me as I walk you through the most recent version of the OWASP Testing Guide and guide you with a few recommendations of my own.

1. The Hardened Application Testing Principles from OWASP Chris Cornutt, ConFoo 2015 - @enygma
2. OWASP: Open Web Application Security Project http://owasp.org
3. “This guide must make its way into the hands of developers and software testers. There are not nearly enough application security experts in the world to make any significant dent in the overall problem. The initial responsibility for application security must fall on the shoulders of the developers, they write the code. It shouldn’t be a surprise that developers aren’t producing secure code if they’re not testing for it or consider the types of bugs which introduce vulnerability.” - Eoin Keary, OWASP Global Board
