Next up is to set the service to start which can be done with sudo service splunk start and you're away. Init script is configured to run at boot. Init script installed at /etc/init.d/splunk. Moving '/opt/splunk/share/splunk/search_mrsparkle/modules.new' to '/opt/splunk/share/splunk/search_mrsparkle/modules'. Generating RSA private key, 2048 bit long modulus Please enter an administrator username: splunk-lab-adminĬopying '/opt/splunk/etc/openldap/' to '/opt/splunk/etc/openldap/nf'.

Otherwise, you cannot log in.Ĭreate credentials for the administrator account.Ĭharacters do not appear on the screen when you type in credentials.

Splunk software must create an administrator account during startup. This appears to be your first time running this version of Splunk. This will generate the following output and prompt you to setup credentials for the web dashboard, make sure you note these down as they're going to be used later on to access the web login.

DPKG will install Splunk, next up is enabling it on boot by using the command: cd /opt/splunk/bin/ Once downloaded it is installed by running:ĭpkg -i splunk-8.1.ģ. The version installed was 8.1 at the time of writing however if you are reading in the future(which you probably are) it may have been updated! Hopefully the process should be the same though.Ģ.

As Splunk free is limited to 500mb/day I'll only be using one host for this post so as to not rip through the quota.įirst thing is first once you've got a few machines setup within a lab, setting up the dashboard where all the logs and forwarders are going to send traffic is key.

This lab will be used for all of the parts of this blue team series but not all hosts will be used in every single post. Splunk Indexer/Server(Ubuntu 19.10 ).The setup I am going to be using will be within the test lab similar to that used in the Paving the way to DA series. The server setup can be on windows or Linux however in this post the server is going to be Ubuntu and the UFs are going to be installed on Windows endpoints within an Active Directory environment. Search Indexer: This is the server that receives input from various UFs setup.

Universal Forwarders: These are the clients, and installed on various systems within a network or estate.Ģ. It works in a client server model, which is split up into:ġ. It takes various inputs of logs and data and it makes them readable by humans, it enables users to search, analyse and visualise data from sources such as servers, end user devices, websites, sensors, devices and everything in-between. It has multiple usages and is not just for security. It is a lot of things, but at a core level it is a digestor and visualizer of data. Quick overview of what Splunk is before diving into the super technical deployment fun.

There are lots of guides out there but via my searching I struggled to find it all in one place, plus I wanted to document the process to make my life easier and hopefully yours too! WTF is Splunk it sounds 💦dirty. So this post is going to be a walk through of deploying it on both server and ingesting logs. I come across Splunk all too often on engagements and have written queries for the dashboard before but I have not deployed it inside my lab from scratch before. I'll be the first to say I'm not a defender at all by trade, but more and more recently I have found myself with a deeper interest in how different tooling slots together from both an offensive and defensive perspective.
