Update Tenable Core Offline
Tenable recommends applying all offline updates to your Tenable Core machine in chronological order. Do not skip offline updates. There are two methods available to perform an offline update. For information about the contents of individual offline update files, see the Tenable Core Release Notes.
Tip: For more information about updating Tenable Core, see the FAQ.
Note: Service pack (SP) updates to OT Security may not be available for an online update in Tenable's repositories. Complete an offline update by downloading the latest installation ISO and performing the offline update procedure if you wish to update your version.
- Tenable Core Tenable.ot Self-Contained Installation ISO - provides latest Tenable.OT ICP/Sensor and system updates (for example, Tenable-Core-Tenable.ot-offline-20231019.iso and Tenable-Core-Tenable.ot.Sensor-offline-20231019.iso)
- Offline Update ISO Image - provides quarterly cadence for ICP/Sensor and system updates (for example, Tenable-Core-Offline-Update-2023-Q3.iso).
To upload a Tenable Core offline update .iso file:
- Navigate to the Tenable Core Offline Update ISO section of the Tenable Downloads page.
-
Click and download the offline update .iso file.
-
Upload the file via scp. For example:
scp local-iso-file.iso user@host:/srv/tenablecore/offlineiso/local-iso-file.isoNote: The target line may vary; however, the destination must be the following path:
/srv/tenablecore/offlineiso/tenable-offline-updates.iso - Rename the offline update .iso file as tenable-offline-updates.iso.
To update Tenable Core via external media:
- Navigate to the Tenable Core Offline Update ISO section of the Tenable Downloads page.
-
Click and download the offline update .iso file.
- Burn the ISO to media (for example, DVD-DL, BD, or thumb drive).
-
Attach the media to a system and have it mount automatically.
Note: By default, the hardening on OL8 operating systems prevents USB media from mounting. In order to use USB drives with a Tenable Core OL8 operating system, the /etc/modprobe.d/usb-storage.conf file needs to be removed from that directory.
