Exploring the detection repository

A detection pipeline should support the rapid creation, testing, maintenance, and deployment of new detections in your environment. While the pipeline should be customized to your own usage, forking an existing pipeline is a good way to start. Multiple organizations have open-sourced their detections and associated pipelines for the broader community. Some examples of this are included in this book’s Appendix. As a starting point, you may wish to see if your chosen product vendor(s) has open-sourced their detections and pipeline, providing a natural starting point. If this does not exist, the Sigma repository and engine is an open source library of detections and a compiler to convert the rules to run in multiple detection environments.

Your detections should be organized to support easy creation and maintenance as your repository continues to evolve. The project layout outlined in Figure 8.1 aims to provide common software development conventions...
