SCADA Security Weak Links

There is an interesting discussion over at Process Automation Usability Project on ControlGlobal.com about a variety of observed weak links in security for electronic control systems. One of the commenters (kkchan) makes the point that the proposed security measure of disabling unused ports and portable media drives “causes unnecessary headaches for day to day (maintenance) activities”. He then invites other SCADA users to provide their comments. Stop on by #pautoup site and join in the discussion. Needless to say I’ve added my two cents to the discussion.
