Advanced OAuth for security-sensitive applications

Dr. Torsten Lodderstedt
Thursday March 12, 14:00 - 15:30
Short description

OAuth has become the standard for API authorization because of its simplicity and versatility. This talk will present battle-proven patterns and OAuth extensions that should be used when building security-sensitive applications.


OAuth is an excellent framework for building both secure and user/developer-friendly APIs. The main reason is that OAuth decouples the interactive user authentication process from the actual API invocations. But is this pattern suited for security-sensitive applications such as payments? How does one ensure it's the legit client requesting the payment with the authorized amount? What about token leakage and other potential attacks? This talk presents design patterns and suitable OAuth extensions that can be used to address these and other challenges arising when building security-sensitive applications.
