Learn how to implement JSON Web Tokens (JWTs) for enhanced security in web applications and microservices architectures. Explore two practical code examples: replacing standard Spring Security CSRF token mitigation with a JWT version, and establishing trust between microservices using JWTs. Gain insights into CSRF tokens, signatures, antipatterns, secure microservices, microservice architecture, and establishing trust in distributed systems. Discover additional topics such as Kafka and OAuth, and access source code and resources for further learning.
