Security is crucial for any application, but implementation can be difficult and it is often neglected, poorly implemented, and intrusive in the code. But lately, security servers such as Auth0 have appeared that outsource and delegate all authentication and authorization aspects. One of the most promising solutions is KeyCloak, an open source, flexible solution that is easy to deploy and adapt in its own infrastructure. In this session, I2019ll use live coding to show how to deploy KeyCloak progressively and demonstrate all aspects of KeyCloak, including securing a Java Enterprise Edition (Java EE) app, a Node.js microservice, an AngularJS web app, or even a mobile app. I2019ll show how to integrate social logins, enable Single Sign On (SSO), and how to bridge to existing identity providers, such as Lightweight Directory Access Protocol (LDAP) and Microsoft Active Directory.
