Elasticsearch Securing a Search Engine While Maintaining Usability

Elasticsearch is running on tens of thousands of nodes world-wide, so despite all the functionality squeezed into new releases, we also have to think about security, all the time. This talk will cover different aspects of Elasticsearch, explain some features and (sometimes unpopular) decisions and the reasoning behind. The goal of this talk is not (only) to show off Elasticsearch features - you should start thinking about these non-functional requirements in your own applications as well!
