We have been speaking about it for almost two years. We have been making it for more than twelve months. And the day (or rather the month in this case) has almost come for TheHive 4, our latest and greatest version, to be unleashed.
While the first release candidate should be published by the end of this month, we would like to cover some of the most important changes we introduced in a platform which we rewrote almost from the ground up (40,000 lines of Scala code and counting), while keeping the familiar look&feel our longtime users came to expect.In a previous blog post, we covered TheHiveFS, a nifty feature of TheHive4 that allows you to quickly access all files stored in TheHive directly from your investigation machine. It’s time now to get a look under the hood of THeHive 4.
My Time is Precious. TL;DR Please
A picture is worth a thousand words, right? Here you go then!
I am Puzzled, can you Elaborate a Bit?
So, you are not in a hurry anymore? Fine. Here, grab a seat, a glass of Gevrey-Chambertin and tasty Burgundy snails. All set? Let’s start then!
TheHive 4 will be the first version to use a graph database instead of Elasticsearch. Yes, you read that correctly. TheHive 4 won’t support Elasticsearch anymore but fear not fearless cyberdefender. Your friendly bees will not leave you hanging. If you are already using TheHive 3.4.x, we will provide a migration tool that will move your existing data to the new storage system (with no losses or bit flips hopefully).
We haven’t decided to ditch Elasticsearch on a whim or because Thomas (Franco, not Chopitea nor the General) dropped his leftist hipster attitude for a tight, tailor-made dictator uniform straight out of Spain. For all its greatness, ES has some annoying limitations which prevented us from adding, in an elegant, haiku-like way important features such as multi-tenancy, RBAC and large file management, while laying the ground for the future (stop being curious, the future has not been invented yet and when we do invent it, we’ll let you know).
Using JanusGraph, TheHive 4 structures information in graphs and stores them in an Apache Cassandra database. All the files that you attach to task logs or add as observables are stored in a Hadoop Distributed File System (HDFS).
Thanks to this brand new architecture, TheHive 4 is horizontally scalable. You can add as many TheHive, Cassandra and HDFS nodes to your Security Incident Response Platform cluster and sustain whatever load you might be facing without a sweat. Who said FOSS can’t be ‘enterprise grade’ (whatever that means in marketing lingo)?
A Tour d’Horizon of the Main Features
TheHive 4, boosted by all the passion and skills of Zen Master Franco and MC Adouani, will support, in addition to TheHiveFS:
- Web configuration
- API versioning
We will cover some of these features in greater detail in future instalments. In the meantime, let’s take a ride in a helicopter and view the wonderful landscape laying before us from above. After you Messieurs-Dames, we are French gentlemen and gallantry is of the essence (except when we use the public transportation in Paris, then savages we become).
As in Cortex, you will be able to create multiple organisations within a single instance of TheHive 4. In addition, an organisation can decide to share a case or parts of it (say a task, some observables, etc.) with other organisations. That way, a peer organisation or a constituent can contribute to the investigation at hand, provide essential information, etc.
TheHive 4 supports a large set of user permissions. Some pertain to administrators, others to users and there are also permissions that apply to connectors. For example, users can manage tasks but not observables. They can have the power to share a case or part of it with sister organisations and execute Cortex analyzers but not responders.
You will be able to create roles for users, and, at the organisational level, what we call shares. RBAC deserves its own blog post and we’ll get to it pretty soon.
Do you really want us to describe this one? Before you answer yes, we’d like to remind you that you are in a helicopter. Just sayin’.
Tired of using vi, Emacs or your favourite CLI editor for making configuration changes to TheHive’s
application.conf? Tired of restarting the service to take into account those modifications? Then you will certainly go dance kizomba with Nabil all night long when we tell you that you don’t need to use
service (or whatever the kids are using these days) anymore!
Thanks to the new architecture, all the configuration will be stored in the underlying database and you will be able to edit it using the WebUI. TheHive will automatically take the changes into account and you won’t need to restart it.
We can feel your love here. Merci !
TheHive 4 adds API versioning and it will maintain backward compatibility with TheHive 3.4.x without preventing us from adding new features. TheHive4py will not be updated right away for TheHive 4 but thanks to the backward API compatibility, all existing feeders and programs that use the current version of TheHive4py will still work out of the box.
That’s all folks! Stay tuned for further news and, in the meantime, don’t be blue cuz’ the bees gonna take care of you.
