API Security Workshop with Dr. Philippe De Ryck (100% Online, Interactive)

Building secure APIs and microservices is hard, really hard. Not only do you have to make the right architectural security decisions, you also have to be aware of various implementation vulnerabilities to ensure the security of your applications. This workshop provides API developers with the necessary knowledge to assess and improve the security of their APIs.


With a mix of lectures, demos, quizzes, and hands-on labs, participants discover best practices for building secure APIs. We investigate various techniques to implement authentication and authorization, along with their trade-offs and pitfalls. We dive deep into handling JSON Web Tokens, but also discuss the relevance of browser security features such as Cross-Origin Resource Sharing. Additionally, we discuss current best practices for securing an API with OAuth 2.0.


This workshop offers practical and immediately applicable security advice for API developers. Throughout the workshop, Philippe is available to answer any questions, including concrete scenarios applying to your own applications.

Didactic Approach


This workshop is not just any workshop. It is packed with in-depth and up-to-date content. We do not merely brush over a threat and defense but focus on the underlying cause and consequences. Why do we have this problem? Which mitigations are often used? Why are some ineffective? Which one is the current best practice? These are the questions that will be answered throughout the workshop.


The workshop consists of a mixture of lectures, demos, interactive quizzes, and hands-on labs. The lectures provide in-depth knowledge of attacks and defenses. The hands-on labs are conducted in a custom-built competitive training environment, allowing participants to gain hands-on experience with offensive and defensive technologies.


Code examples and demos often use NodeJS and Spring Boot, but are easy to translate to other languages and frameworks.
