IGEL Linux version 5.11.100 or newer and IGEL Linux version 10.01.100 or newer allow terminal access via UMS with transport encryption. In analogy to secure shadowing, network traffic is encrypted with TLS/SSL. Secure terminal connections can only be initiated from the UMS whose certficate is stored on the device.

For details about setting up a secure terminal connection, see UMS manual Secure Terminal (Secure Shell).   

Secure Terminal is the best way to create a remote access from the UMS (on Linux or Windows installed) to Linux devices, without installing an additional terminal software. Because the UMS includes the software.
