Spring Security With OAuth2
Spring Security provides comprehensive security services for J2EE-based enterprise software applications. It is powerful, flexible, and pluggable. It is not like a Proxy server, firewall, OS level Security, Intrusion Detection System, or JVM Security.
OAuth is an open-authorization protocol that allows accessing resources of the resource owner by enabling the client applications on HTTP services, such as Gmail, GitHub, etc.
