Reducing the amount of software running on a system reduces its attack surface. Therefore a basic security measure for IGEL OS 10 is to remove all unused features.
Instructions
By default IGEL OS comes with a wide variety of features enabled. To disable any of these, do the following:
In the IGEL Setup go to System > Firmware Customization > Features.
Uncheck all the features that you do not intend to use. If you do not use local printers on the endpoint device that you want to share with others, uncheck:
Printing (Internet Printing Protocol CUPS)
Printing (Line Printer LPD)
Printing (TCP/IP)
Printing (ThinPrint)
Do not remove the Custom Partition feature if you have a custom partition that contains software or data for which you have no backup copy. After disabling the feature and a reboot the contents of the custom partition will be lost.
