Eric Byres has updated his recommendations for security of SCADA systems from the Stuxnet worm as a result of the Microsoft patch. His revised white paper “Siemens PCS7 WinCC Malware” is available for download by all Tofinosecurity.com members now. (If you are not a member, you can become one by signing up. There is no charge and Byres says he’s created a very complete program to ensure member privacy.)
