MozDef uses the Meteor framework for the web interface and bottle.py for the REST API. For authentication, MozDef supports local account creation. Meteor (the underlying UI framework) supports many authentication options including google, github, twitter, facebook, oath, native accounts, etc.
Since the backend of MozDef is Elastic Search, you get all the goodness of Kibana with little configuration. The MozDef UI is focused on incident handling and adding security-specific visualizations of SIEM data to help you weed through the noise.
