In this presentation, Michel Chamberland will leverage the Trustwave SpiderLabs team’s experience conducting a large volume of web application security assessments and share information on trends on web application vulnerabilities. SpiderLabs is an elite team of over 150 information security professionals distributed across the globe who conduct web application security assessments on an ongoing basis across all vertical markets. The team performs many thousands of web application security assessments every year. During this presentation, trends and statistics in web application vulnerabilities as observed by the SpiderLabs team will be reviewed. The most commonly found vulnerabilities will then be discussed at a high level as to what they are, why they are important and how they are often mitigated.
