Synthetic Adversarial Log Objects (SALO) is a framework for the generation of log events without the need for infrastructure or actions to initiate the event that causes a log event. The purpose of this framework is to allow security practitioners, data scientists, and researchers the ability to create log events in a simple, repeatable, and randomized way without the overhead of traditional required resources.

In the past, in order to generate simple network security logs, such as DNS queries for a malicious domain, it would be required to build one or more servers, as well as a network monitoring solution to capture events. Additionally, the DNS queries would have to be sent to a resolver with no simple way to construct custom requests or responses. This process can be time consuming, present technical and financial hurdles, and be extremely cumbersome or difficult to accomplish. This is especially so for more complex scenarios that may require highly technical deployments of software, services, and/or cloud native technology.

SALO seeks to simplify the task of creating and collecting log events from any source that generates them by constructing models for such events and a simple method for defining attributes and their values.

Create a new venv for SALO:

$ python3 -m venv ~/.venv/salo

Activate the new venv environment:

$ source ~/.venv/salo/bin/activate

Clone the respository:

$ git clone https://github.com/splunk/salo

Change directories to the newly cloned one:

$ cd salo

Then, install SALO and neccessary requirements:

$ pip3 install -e .

Once installed, you can simply run salo. Multiple example recipes can be found in the examples/recipes/ folder:

$ salo recipe examples/recipes/beacon.yaml

For more advanced use cases of SALO, take a look at some example recipes as well as the project documentation.
