Offline NNM Plugin Update in Tenable.sc

To perform an offline NNM plugin update:

  1. If not already in place, install a NNM scanner on the same host as Tenable.sc. It does not need to be started or otherwise configured.

  2. To prevent the NNM scanner from starting automatically upon restarting the system, run the following command:

    # /sbin/systemctl is-enabled nnm off

  3. Run the following command and save the challenge string that is displayed:

    # /opt/nnm/bin/nnm –challenge

  4. Do one of the following:
  5. Paste the challenge string from Step 3 and your Activation Code in the appropriate boxes on the web page.
  6. Click Submit.
  7. On the next page, copy the link that starts with https://plugins.nessus.org/v2/... and bookmark it in your browser. The other information on the page is not relevant for use with Tenable.sc.
  8. Click the bookmarked link.

    The page prompts you to download a file.

  9. Download the file, which is called sc-passive.tar.gz.
  10. Save the sc-passive.tar.gz on the system used to access your Tenable.sc GUI.

Note: Access the NNM feed setting and change the activation from offline to Tenable.sc.
