+## Reporting a Vulnerability
+
+The current process for reporting vulnerabilities is outlined here: https://www.apache.org/security/. When reporting a
+vulnerability to security@apache.org, you can copy your email to [private@pulsar.apache.org](mailto:private@pulsar.apache.org)
+to send your report to the Apache Pulsar Project Management Committee. This is a private mailing list.
+
+## Using Pulsar's Security Features
+
+You can find documentation on Pulsar's available security features and how to use them here:
+https://pulsar.apache.org/docs/en/security-overview/.
+
+## Security Vulnerability Announcements
+
+The Pulsar community will announce security vulnerabilities and how to mitigate them on the [users@pulsar.apache.org](mailto:users@pulsar.apache.org).
+For instructions on how to subscribe, please see https://pulsar.apache.org/contact/.
+
+## Versioning Policy
+
+The Pulsar project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html). Existing releases can expect
+patches for bugs and security vulnerabilities. New features will target minor releases.
+
+When upgrading an existing cluster, it is important to upgrade components linearly through each minor version. For
+example, when upgrading from 2.8.x to 2.10.x, it is important to upgrade to 2.9.x before going to 2.10.x.
+
+## Supported Versions
+
+Feature release branches will be maintained with security fix and bug fix releases for a period of at least 12 months
+after initial release. For example, branch 2.5.x is no longer considered maintained as of January 2021, 12 months after
+the release of 2.5.0 in January 2020. No more 2.5.x releases should be expected at this point, even to fix security
+vulnerabilities.
+
+Note that a minor version can be maintained past it's 12 month initial support period. For example, version 2.7 is still
+actively maintained.
+
+Security fixes will be given priority when it comes to back porting fixes to older versions that are within the
+supported time window. It is challenging to decide which bug fixes to back port to old versions. As such, the latest
+versions will have the most bug fixes.
+
+When 3.0.0 is released, the community will decide how to continue supporting 2.x. It is possible that the last minor
+release within 2.x will be maintained for longer as an “LTS” release, but it has not been officially decided.
+
+The following table shows version support timelines and will be updated with each release.
+
+| Version | Supported          | Initial Release | At Least Until |
+|:-------:|:------------------:|:---------------:|:--------------:|
+| 2.9.x   | :white_check_mark: | November 2021   | November 2022  |
+| 2.8.x   | :white_check_mark: | June 2021       | June 2022      |
+| 2.7.x   | :white_check_mark: | November 2020   | November 2021  |
+| 2.6.x   | :x:                | June 2020       | June 2021      |
+| 2.5.x   | :x:                | January 2020    | January 2021   |
+| 2.4.x   | :x:                | July 2019       | July 2020      |
+| < 2.3.x | :x:                | -               | -              |
+
+If there is ambiguity about which versions of Pulsar are actively supported, please ask on the [users@pulsar.apache.org](mailto:users@pulsar.apache.org)
+mailing list.
