Abstract—Since 2014, Microservice Architecture (MSA) has been widely applied and deployed by big companies such as Google, Netflix and Twitter. This is a way of architecting software systems in which the services of a single application are decomposed then deployed and executed separately. This research examines the possibility of applying Spring Security Framework and OAuth2 to secure microservice APIs which are built on top of Spring Framework. By developing a Proof of Concept (POC) of an Inventory Management System using MSA on top of Spring Framework, Spring Security Framework and OAuth2. we have conducted security tests over the POC using unit testing and manual testing techniques to examine if there are any vulnerabilities and we were able to show and confirm the effectiveness of the Spring Security Framework and OAuth2 in securing Spring-based APIs.

Index Terms—Software architecture, microservice architecture (MSA), oauth2, spring framework, and POC.
