If a user has a PC at home that's permanently connected to the 'net
via ADSL, DSL or a cable modem, and uses his old serial port modem to
dial up a terminal (PPP) server inside our firewall protected network,
then our network security depends on the inability of his home PC to
route packets (or to be subverted so that it routes packets).
Are there any products out there that run on users home PCs (Windows
95/98, Macintosh, Linux, ???) that will disable the network interface
card while the serial port modem is in use?
Does anyone have any suggestions on how I can address this seeming
vulnerability? Deep sixing the terminal server is a good idea, but
probably won't fly.
Thanks,
Walt
