Explore a comprehensive overview of implementing microservices security patterns and protocols using Spring Security in this 46-minute conference talk from Spring I/O 2019 in Barcelona. Gain insights into industry-standard protocols such as JWT, JWA, JWS, JWE, JWK, OAuth2, OpenID Connect, and TLS, and learn how to combine them effectively for secure microservices development. Discover practical implementations of key security patterns, including Web SSO Login, OAuth2 resource servers, edge service gateways, token exchange and relay in microservice call chains, and integration with OpenID Connect / OAuth2 servers. Follow along with demo and code walkthroughs that demonstrate how to apply these patterns and standards using Spring Security 5. Delve into topics such as architecture, OpenID Authentication and Discovery, Resource Server Configuration, OAuth Client setup, Web Client implementation, and fine-grained authorization to enhance your microservices security knowledge and skills.
