How to safely connect to remote embedded systems (mostly behind Firewalls) ?

Hello,

I'm preparing buildroot based distribution for ARM Cortex M7 (noMMU,STM32F769 DISCO board).

I'd like to implement possibility to remotely connect from distant server, to check and supervise the system.

I think that >reverse shell< is what I'm looking for (so remote system on some trigger connects safely to some distant server, from which I can work in shell). I guess dropbear that is already present in my system could be used for this.

Is this solution safe and how can be implemented efficiently on these resource constrained devices ?

Thanks,

Regards,

Rob.
