+# Security Policies and Procedures
+
+## Reporting a Bug
+
+The `forwarded` team and community take all security bugs seriously. Thank
+you for improving the security of the project. We appreciate your efforts and
+responsible disclosure and will make every effort to acknowledge your
+contributions.
+
+Report security bugs by emailing the current owner(s) of `forwarded`. This
+information can be found in the npm registry using the command
+`npm owner ls forwarded`.
+If unsure or unable to get the information from the above, open an issue
+in the [project issue tracker](https://github.com/jshttp/forwarded/issues)
+asking for the current contact information.
+
+To ensure the timely response to your report, please ensure that the entirety
+of the report is contained within the email body and not solely behind a web
+link or an attachment.
+
+At least one owner will acknowledge your email within 48 hours, and will send a
+more detailed response within 48 hours indicating the next steps in handling
+your report. After the initial reply to your report, the owners will
+endeavor to keep you informed of the progress towards a fix and full
+announcement, and may ask for additional information or guidance.
