Hmm, one would ask why it is connected to the Internet or allowed to surf.
That's the 'SC' and 'DA' parts of SCADA. Traditionally, controllers would use uart to send data (often via a modem). The trend in scada gear is to use commodity IP-speaking hardware (even using embedded windows clients for the controllers). Until recently, the chlorination for the water I drink daily was admin'd on a win95 machine, which needed frequent rebooting because of viruses. That's because the historic threat to the city's water supply was chiefly the odd stray horse that would drown in one of the reservoirs. The new threat, of course, includes news outlets, with their devastating ability to distort budget priorities. -- David Dagon /"\ "When cryptography dagon () cc gatech edu \ / ASCII RIBBON CAMPAIGN is outlawed, bayl Ph.D. Student X AGAINST HTML MAIL bhgynjf jvyy unir Georgia Inst. of Tech. / \ cevinpl." _______________________________________________ Fun and Misc security discussion for OT posts. https://linuxbox.org/cgi-bin/mailman/listinfo/funsec Note: funsec is a public and open mailing list.
