+# Security Policy
+
+This security policy applies to all projects under the [open-telemetry organization][gh-organization] on GitHub. Security reports involving specific projects should still be reported following the instructions on this document: the report will be shared by the technical committee to the project leads, who might not all have access to the private key required to decrypt your message.
+
+## Supported Versions
+
+The OpenTelemetry project provides community support only for the last minor version: bug fixes are released either as part of the next minor version or as an on-demand patch version. Independent of which version is next, all patch versions are cumulative, meaning that they represent the state of our `master` branch at the moment of the release. For instance, if the latest version is 0.10.0, bug fixes are released either as part of 0.11.0 or 0.10.1.
+
+Security fixes are given priority and might be enough to cause a new version to be released.
+
+## Reporting a Vulnerability
+
+If you find something suspicious and want to report it, we'd really appreciate!
+
+### Ways to report
+
+* It is preferable to always encrypt your message, no matter the channel you choose to report the issue
+* Send a message to [[email protected]][mailing-list]
+* If you can't send an email, either open an issue on GitHub with the description or open a pull request on GitHub with a reproducer and/or fix. We really prefer if you'd talk to us per email, though, as our repositories are public and we would like to give a heads up to our users before disclosing it publicly.
+
+### Our PGP key
+
+No matter what channel you choose to communicate with us, we would prefer you to encrypt your message using our [published key][published-key], which is available on all major key servers and should match the one shown below. If you are new to PGP, you can run the following command to encrypt a file called "message.txt":
+
+1. Receive our keys from the key server:
+
+    `gpg --keyserver pool.sks-keyservers.net --recv-keys 936EAAD588D07C19`
+
+2. Encrypt a "message.txt" file into "message.txt.asc":
+
+    `gpg -ea -r 936EAAD588D07C19 message.txt`
+
+3. Send us the resulting "message.txt.asc"
+
+**Our published key should match this one:**
