Sure--depends on how you've configured your LAN, though.  If you're
using the Linux box as a firewall, you put a second NIC in it and either
connect her to that, or (more useful) put a switch on it so you have
more than one connection.

If you're NOT using the Linux box as a firewall, then you absolutely
should get a firewall appliance between the cable modem and your LAN.
All of these have at least four, usually five LAN ports.

Thanks, Dave. I have still no LAN (as far as I am aware of it); I only
have a single computer and a modem to connect to the Internet. What do
you mean by NIC? How can I know whether I have already got NICs in my
computer?
