Johan-p / sysmon-modular

A repository of sysmon configuration modules

sysmon-modular | Personal fork

See https://github.com/olafhartong/sysmon-modula for original version

This is a Microsoft Sysinternals Sysmon configuration repository, set up modular for easier maintenance and generation of specific configs.

The sysmonconfig.xml within the repo is automatically generated after a successful merge by the PowerShell script.

Customization

You will need to install and observe the results of the configuration in your own environment before deploying it widely. For example, you will need to exclude actions of your antivirus, which will otherwise likely fill up your logs with useless information.

Generating a config

PowerShell

$> git clone https://github.com/Johan-p/sysmon-modular.git
$> cd sysmon modular
$> . .\Merge-SysmonXml.ps1
$> Merge-AllSysmonXml -Path ( Get-ChildItem '[0-9]*\*.xml') -AsString | Out-File sysmonconfig.xml

Use

Install

Run with administrator rights

sysmon.exe -accepteula -i sysmonconfig.xml

Update existing configuration

Run with administrator rights

sysmon.exe -c sysmonconfig.xml

To understand added features in the latest version, have a look at my small blog post or watch my DerbyCon talk

Note: I do recommend using a minimal number of configurations within your environment for multiple obvious reasons, like; maintenance, output equality, manageability and so on.

More information

I started a series of blog posts covering this repo;

• Endpoint detection Superpowers on the cheap - part1 - MITRE ATT&CK, Sysmon and my modular configuration
• Endpoint detection Superpowers on the cheap — part 2 — Deploy and Maintain
• Endpoint detection Superpowers on the cheap — part 3 — Sysmon Tampering

Required actions

I highly recommend looking at the configs before implementing them in your production environment. This enables you to have as actionable logging as possible and as litte noise as possible.

Mitre ATT&CK

I strive to map all configurations to the ATT&CK framework whenever Sysmon is able to detect it. A current ATT&CK navigator export of all linked configurations is found here and can be viewed here

Final thanks to Mathias Jessen for his Merge script, without it, this project would not have worked as well.
