Ensure swarm services are bound to a specific host interface.

Linux: List the network listener on port 2377/TCP (the default for docker swarm) and confirm that it is only listening on specific interfaces. For example, using ubuntu this could be done with the following command:

netstat -lt | grep -i 2377

If the swarm service is not bound to a specific host interface address, this is a finding.
