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.

above, the first item below and this article from
Norman Data Defence Systems about SCADA
prevention/mitigation White Paper updated
Byres Security has produced a new edition of its White
Paper "Analysis of the Siemens WinCC / PCS7 'Stuxnet'
Malware for Industrial Control System Professionals."
