#Databricks v.s. Zeppelin This article is about data exploration and two of the main tools that are currently available on the market, Databricks community and Apache Zeppelin Both Zeppelin and Databricks provide a similar interface to explore your data.

This is the third article in the series of hardening this webserver. If you have not read them, please read: Protecting my Webserver and SSL Cypher hardening. In this article, I show the usage of the Content-Security-Policy header. This header helps you reduce XSS risks on modern browsers by declaring what dynamic resources are allowed to load via an HTTP Header.

Just recently I finished an article for the Dutch Java magazine about securing your website by means of https connections. In the article, we (Ivo Woltring and I) describe details on how to get a certificate for your Webserver from the LetsEncrypt CA.
The end result of those steps is a site that only allows for https connections. This solved the problem of others listening in on your visitors. Hacking your site is definitely more difficult, but not all possibilities are resolved.
