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

[rob.r374 at gmail.com]

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.
