Security - Is there a way to protect access if the node is compromised?

Question

I would like anyone from executing commands through multichaind, multichain-util or mutlichain-cli on the blockchain if they maliciously get access to the unix box on which my node is running.

Answer 1

I'm afraid this will not be a fruitful avenue of security. It's better to think about how to set things up so that if a single unix box is compromised, only very limited damage is done. This is already part of the philosophy of how blockchains work, to be immune to the compromise of a single node. But you can add on top things like multisignature addresses, and also use the admin consensus mechanism.
