Rarely does something from the world of machine building find its way into the mainstream press, but the Stuxnet Trojan has achieved that feat. Much has been written about the way it is a highly focussed and well-written piece of code that targets Microsoft Windows PCs with WinCC and PCS 7 - and if that includes equipment you or your customers have on site, here is a link to the relevant support page on the Siemens website. Bear in mind, however, that the general threat from malware on industrial control systems extends much wider.
No doubt there are, as you are reading this, people frantically rewriting functional requirements specifications for new machines, adding clauses relating to cyber security. Specifiers and buyers are starting to place as much emphasis on cyber security as they do on factors such as throughput, reliability, quality and safety. After all, the direct and indirect costs of a malware-induced incident could be just as substantial, whereas the cost of taking appropriate preventative action is comparatively small.
For more information on this subject, see the link above, the first item below and this article from Norman Data Defence Systems about SCADA system security.
