Elastic Security has open sourced all our detection rules to work alongside the security community to stop threats at scale and arm every analyst. As part of our belief in the power of open source, Elastic includes prebuilt rules within the Security App to detect threats automatically. In this video, you’ll learn how you can contribute by creating a new rule, adding your new rule to the detection rules repo, and getting credit for it in the Elastic contributor program.
