We find security vulnerabilities almost everywhere. Few developers build perfect systems, and dealing with security vulnerabilities is about managing risks. It’s becoming more important to deal with security in a structured way, as threats and attacks are on the rise. This session will introduce and discuss the "CWE/SANS Top 25 Most Dangerous Software Errors". You will learn how the Top 25 is structured, and how you can work with it in your development projects. You will see hack demos and examples of vulnerable products, and understand how such vulnerabilities can be avoided at an early stage in development.
