+================
+Security process
+================
+
+What is a vulnerability?
+------------------------
+All vulnerabilities are bugs, but not every bug is a vulnerability.
+Vulnerabilities compromise one or more of:
+
+* Confidentiality (personal or corporate confidential data).
+* Integrity (trustworthiness and correctness).
+* Availability (uptime and service).
+
+If in doubt, please use the process for `reporting a vulnerability`_, and we
+will assess whether your report is in fact a security vulnerability, or if it
+should be `reported as a bug`_ using the normal bug process.
+
+Reporting a vulnerability
+-------------------------
+To report a security issue, please email `[email protected]`_ with a
+description of the issue, the steps you took to create the issue, affected
+versions, and, if known, mitigations for the issue.
+
+The `Ubuntu Security disclosure and embargo policy`_ contains more information
+about what you can expect when you contact us and what we expect from you.
+
+Product lifetime
+----------------
+The main components of MicroOVN, Open vSwitch (OVS) and Open Virtual Network
+(OVN), comes from the Ubuntu distribution.  Releases of MicroOVN in stable
+:ref:`snap channels` that align with Ubuntu Long Term Support (LTS) releases,
+receive the same level of support throughout the lifetime of the corresponding
+Ubuntu LTS release.  Please refer to the `Ubuntu lifecycle and release
+cadence`_ documentation for more information.
+
+Tracking vulnerabilities
+------------------------
+Vulnerabilities, their status, and the state of the analysis or response will
+all be tracked through the `Ubuntu CVE tracker`_.
+
+Responding to vulnerabilities
+-----------------------------
+Vulnerabilities are classified by `priority`_, and the MicroOVN project
+guarantees response to all High and Critical severity vulnerabilities, as well
+as any `Known Exploited Vulnerability`_.
+
+Security updates will be made available to consumers of stable :ref:`snap
+channels` that align with supported Ubuntu Long Term Support (LTS) releases.
+
+The MicroOVN snap is automatically rebuilt by Launchpad whenever there is an
+update to the underlying packages in the Ubuntu distribution.
+
+Updated versions of the snap will be put through the MicroOVN functional test
+suites before being promoted to stable :ref:`snap channels`.
+
+Information about new builds are made available through the `Snap store`_.
+
+Responsible disclosure
+----------------------
+We follow the `Ubuntu Security disclosure and embargo policy`_.  Please refer
+to the section on `reporting a vulnerability`_.
