sigma-cli 0.4.0

Sigma Command Line Interface (conversion, check etc.) based on pySigma

Sigma Command Line Interface

This is the Sigma command line interface using the pySigma library to manage, list and convert Sigma rules into query languages.

Getting Started

Installation

The easiest way to install the Sigma CLI is via pipx or pip. For this purpose run one of the following:

python -m pipx install sigma-cli
python -m pip install sigma-cli

Another way is to run this from source in a virtual environment managed by Poetry:

git clone https://github.com/SigmaHQ/sigma-cli.git
cd sigma-cli
poetry install
poetry shell

Usage

The CLI is available as sigma command. A typical invocation is:

sigma convert -t <backend> -p <processing pipeline 1> -p <processing pipeline 2> [...] <directory or file>

E.g. to convert process creation Sigma rules from a directory into Splunk queries for Sysmon logs run:

sigma convert -t splunk -p sysmon sigma/rules/windows/process_creation

Available conversion backends and processing pipelines can be listed with sigma list.

Backends can support different output formats, e.g. plain queries and a file that can be imported into the target system. These formats can be listed with sigma list formats <backend> and specified for conversion with the -f option.

In addition, an output file can be specified with -o.

Example for output formats and files:

sigma convert -t splunk -f savedsearches -p sysmon -o savedsearches.conf sigma/rules/windows/process_creation

Outputs a Splunk savedsearches.conf containing the converted searches.
