The Top 10 Web application security risks produced by OWASP is an evolving resource that helps organizations focus on the most prominent risks in web security today. Every few years we see a revision; the types of attacks we're witnessing change, the defenses change, and the risk and associated priority changes. OWASP adapts to this changing environment and recently made available the 2013 edition of the Top 10. This course is designed to help those who already have an awareness of the Top 10 understand what's new in the latest edition and how the landscape has changed in three short years. It also introduces the concept of “Risk Assessments” and provides further resources to help go beyond just the Top 10 risks.
