Abstract. Security issues regarding microservice are well researched, however the different security issues and solutions have not been brought together as yet. This study searched through academic databases to find out what security issues and proposed solutions or mitigation methods can be found in existing literature. It found several security issues and methods in literature. Most security issues are raised regarding microservice that externally facing or in open environment. Majority of sources addressed security monitoring and authentication and authorization issues, fewer studies on implementation and bug-related issues such as container implementation and -bugs and some on networking related issues. This study found also that there is some amount of disconnect in literature when it comes to addressing security issues and their solutions and mitigation methods. The study offers a more detailed account of existing microservice security issues and solutions
