I did a preliminary search and was unable to find an exact / similar question.
I'm configuring a server in our network, in order to give SSH access to a normal user from a third party.
I'm trying to isolate the server from the network using
IPTables on the server. My idea is to block outgoing
SSH access to other parts of the network.
I'm asking whether this is enough, or should I block anything else, or what precautions should I take on the
IPTables side only.
The third party won't have
root or elevated access. They'll be able to SSH to server from a single static IP only.
