Hi,
Is it possible for my PC to get a virus thrugh the serial port?
I have an industrial computer directly connected to another PC through
a serial port. This industrial PC ONLY connects to this other PC
through the serial port, although the PC itself is connected to the
corporate network, and ultimately to the internet.

I have been advised that the industrial PC should have some antivirus
software installed due to this serial port connecton.

What do the list think about this? Is it possible to get a virus
through the serial port?
Both computers are running XP. The programs which communicate over
serial are custom applications developed by me.

It has already been suggested that the industrial PC has USB ports so
it is possible to get a virus onto the industrial PC through that, so
that initself would warrant installing antivirus software, but I was
more interested in the possibilities of how a virus would get through
the serial port.

Thanks for looking.

Regards

It all depends upon what protocols are used on the serial port.  If it uses
TCP/IP - yes.
A virus could spread over the serial port.

As best as I know it.

The way you get a virus is the transfer of data, if that data is infected
with a virus, the data/virus cares not whether it is transferred by USB,
DB9, DB25, modem or network interface it is simply transferred.
(and what protocols are open on those ports)

If your only communication between the PC's is the serial connection and the
other PC is connected to the Internet, then I would feel pretty secure if
the PC connected to the Internet had a good anti-virus program on it,  and
since that is the only point of entry then if your first PC is scanned to be
virus free then the second PC should be pretty safe.

I would be concerned about a firewall and all the security updates from
Microsoft, on both PC's.

If you still feel the need to put an anti-virus program on the industrial PC
think,  how will you update the virus definitions? USB drive etc, because if
your definitions are not up to date, the anti-virus program becomes outdated
and ineffective.
