 This repo uses semantic versions. Please keep this in mind when choosing version numbers.
 
+1. **Verify all dependencies are up-to-date**
+
+   Before you start a release, make sure all dependencies are up-to-date, or are documented why not.
+   Pay special attention to the [security workflow](.github/workflows/security.yml), which should
+   run clean.

 1. **Alert others you are releasing**
 
    There should be no commits made to master while the release is in progress (about 10 minutes). Before you start

+# OpenZipkin Security Process
+
+This document outlines the process for handling security concerns in OpenZipkin projects.
+
+Any vulnerability or misconfiguration detected in our [security workflow](.github/workflows/security.yml)
+should be addressed as a normal pull request.
+
+OpenZipkin is a volunteer community and does not have a dedicated security team. There may be
+periods where no volunteer is able to address a security concern. There is no SLA or warranty
+offered by volunteers. If you are a security researcher, please consider this before escalating.
+
+For security concerns that are sensitive or otherwise outside the scope of public issues, please
+contact zipkin-admin@googlegroups.com.
