 As was stated previously, running the ``Generate Vulnerabilities`` Job will not modify (or delete) any existing Vulnerability objects - **even if the associations that existed previously no longer exist**. You do have the ability to delete one or more Vulnerability objects via the GUI or API. In addition to manually removing a Vulnerability, if any CVE, Software, Device or Inventory Item objects are removed, any Vulnerability objects that reference the deleted items will also be removed automatically.

+## Automated CVE Discovery via NIST API 2.0
+The NTC Nautobot Device Lifecycle Management app now supports automated CVE discovery via the NIST NVD API 2.0.  This feature is optional and can be enabled by obtaining an API key, updating the necessary Secret, and running the ``NIST - Software CVE Search`` Job. Continue reading for more information.
+
+### External Integration
+An External Integration must be created and configured in order to use the NIST NVD API for automatic software CVE discovery. On this note, the following is installed for you:
+
+- A new External Integration object named ``NAUTOBOT DLM NIST EXTERNAL INTEGRATION`` that allows you to control the following behaviors of the integration:
+    - ``api_call_delay``: A delay between API calls in seconds (default: 6).  NIST Recommends a minimum value of 6 to prevent overloading resources.
+    - ``retries``: Even with using a delay, the NIST API may return a 500 error.  The settings in this dictionary allows you to control the number of retries and backoff.
+        - ``max_attempts``: The maximum number of retry attempts (default: 3).
+        - ``backoff``: The backoff factor for the retry attempts (default: 2).  This is the multiplier for the delay between retries.
+- A new Secrets Group object named ``NAUTOBOT DLM NIST SECRETS GROUP`` used for access to the NIST API Key from the External Integration.
+- A new Secret object named ``NAUTOBOT DLM NIST API KEY``.  This object is created for you during setup with minimum defaults.  The Secret name must be exactly as above, but you will need to configure the Secret to properly access the NIST API Key.
+    - To obtain your NIST API Key go [here]('https://nvd.nist.gov/developers/request-an-api-key').
+
+NOTE: You may change the name of the External Integration or create your own using other configuration settings, but the SecretsGroup and Secret objects must be named as above.  The External Integration is selected when starting the Job run.
+
+
+### Run Job
+Automated discovery is used by running the ``NIST - Software CVE Search`` Job.
+
+To run this job, use the "Jobs" menu dropdown and navigate to the **CVE Tracking** section. The jobs will appear here and all you will need to do is click the play button in order to use the default External Integration[^1].  If you have configured additional Integrations, you may select the External Integration that you want to use.  **As stated previously, the name of the External Integration does not matter, but the External Integration must contain a SecretsGroup and Secret named as above**.

+
+![](../images/lcm_cve_nist_job_run.png)
+
+The job output should indicate the softwares checked and the amount of CVEs received for that software, as well as the amount of CVEs created.  These will not always be the same.  New CVE will be created for software with existing CVE, also software will share CVEs.
+
+![](../images/lcm_cve_nist_job_log.png)
+
+[^1] Warning: If play button is grayed out. You will need to enable the job by clicking on edit button in the row and navigate to "Job" portion and click on "Enable"
+
+
+### Additional Notes:
+Due to the way vendor platform entries vary in NIST, some platforms may work without issue, others may not work so well (false positives/negatives).  Juniper JunOS is a great example and has a custom parser in netutils to handle this.
+
+If the platform you are attempting to gather information from does not work, a custom parser will likely be needed to build a proper NIST search URL.
