Connect your Arduino (or any serial device port) to a Raspberry Pi (a Zero cost very little if cost is an issue) and then you can SSH to the R-Pi and/or forward ports with SSH to minicom, picocom, web gateway interfaces, or whatever you want.

An R-Pi runs Linux (e.g. an operating system) which is the sort of place you find SSH. An Arduino is what some call bare metal, it has no operating system, and no SSH. Bare metal networking is risky business and SSH has not been ported (e.g. libssh was not part of any Arduino stuff).
