How to Keep the System Up-To-Date

Rationale

Software updates fix newly discovered vulnerabilities in IGEL OS and applications. This means that keeping up with updates is one of the most important measures in securing IGEL OS systems.

To start and configure updates, you can use IGEL Setup and/or the Universal Firmware Update feature of the Universal Management Suite (UMS).

The instructions described on this page use the Universal Firmware Update feature of the UMS. For defining a scheduled job, see the section "As a Job" in Universal Management Suite > UMS Reference Manual > Devices > Managing Devices > Assigning Updates; for configuring the update on a device, see Firmware Update Settings for IGEL OS. 

Instructions

→ To get new ISNs and ISN updates delivered to your inbox, subscribe to the Security Announcements Mailing List. Go to http://igel.com  and find the "Subscribe for Updates" form at the bottom of the page. This will initially subscribe you to all mailings from IGEL, but by using the unsubscribe link at the bottom of a mail, you can select which communications you wish to receive and which not.

The upgrade procedure consists of the following steps:

• Getting the update from the IGEL download server

• Testing the update on one or a few devices

• Rolling out the update on all devices
