In the IGEL Universal Management Suite (UMS), you can enable a secure terminal session and a secure VNC connection globally.

Menu path: UMS Console > UMS Administration > Global Configuration > Remote Access

Secure terminal

Enable secure terminal globally

Access via the secure terminal is enabled for all registered devices.

Access via the secure terminal cannot be enabled for all registered devices. However, it can be enabled for individual devices. (Default)


Log user for secure terminal: Specifies whether the user name of the UMS user who established the connection to the device is logged. The log is shown under System > Logging > Log secure access.

The user name is contained in the log.

The user name is not contained in the log. (Default)

Secure VNC

Enable secure VNC globally

Access via secure VNC is enabled for all registered devices.

Access via secure VNC is not enabled for all registered devices. However, it can be enabled for individual devices. (Default)

Secure Shadowing and IGEL OS 12

There is no need to enable secure shadowing since shadowing of IGEL OS 12 devices is always via Unified Protocol, i.e. communication is always encrypted. However, you can activate secure shadowing if you want that the devices could be shadowed via the UMS only (internal VNC or external VNC viewer). Shadowing of the devices by another computer is then not possible.


Log user for secure VNC: Specifies whether the user name of the UMS user who established the connection to the device is logged. The log is shown under System > Logging > Remote Access.

The user name is contained in the log.

The user name is not contained in the log. (Default)
