Securing a sample fraud graph with Neo4j 4.0

This week, we at Neo4j formally released our brightest and shiniest new version of the Neo4j Graphg Database to the world. It's been an amazing journey to this point, and others have reported on this magnificent piece of engineering in more depth. Take a look at Jim's blogpost, or if you are in a hurry, checkout the graphcast below:

Last week, I started playing around with it myself - by digging up my good old faithful beergraph, and illustrating some of the new features in childproofing exercise for beers. Take a look at that post as well for some giggles. Now in this post, I wanted to essentially do the same thing as I did on the beergraph, but using a Fraud dataset. 

Let's see how that would work.

Securing my Beergraph with Neo4j 4.0

Not sure if you have realised, but Neo4j has actually recently made the 4.0 version of the most fantastically awesome graph database on the planet available. You can get it ahead of the big launch event (on February 4th, 2020 - in case you were wondering!) from the Download Center and take it for a spin.

In this unbelievable release, there are so many new features, it's kind of hard to keep track of everything. But the ones that I can most easily get my head around are clearly

1. multi-database support - finally, Neo4j actually has this concept of running multiple databases on one database server. A multi-tenancy solution, that has been requested and anticipated by many of our users and customers. 
2. a VERY advanced schema-based security module, that allows people to extend the existing role-based security model of Neo4j even further - and make it crazy powerful. We'll spend a lot of time on that in this blogpost.

Readers of this blog probably know that I am a big fan of getting my feet down and dirty with our products, so this evening - with a couple of hours to spare, so to speak - I decided to try out the shiny new release. I spun up my Neo4j Desktop, and started reading some manual pages where stuff was explained. Specifically, I loved

• the manual pages on managing multiple databases
• the pages on authentication and authorisation
• a great video by Louise Söderström from Neo4j engineering:

Soon after flipping through this, I was on my way.
