It's an issue on any network, especially if the machines are sharing
resources. The machines are protected from the Internet, but once one is
infected or compromised, the machine can reach out and attack other machines
on the LAN, or someone could remotely go after other machines on the LAN.
You could get a router and that way you could reduce the risk from the other
machine, because you had to do ICS with the other machine. The router allows
the other machine to access the Internet independently not needing the main
computer to provide the access to the Internet. And if you got a router that
had a print server, you could further reduce the risk, since you wouldn't
need to share the printer on the main computer.
If you had to do file sharing with the other machine, you limited it to one
directory on both machines and place files in like the *Transfer*
directories, which could reduce risk.
For me, I just put an IDS/firewall application on each machine knowing that
it will help protect the machines from each other and help stop an attack
from a compromised machine on the LAN, even if resources are being shared
between machines.
