Jim Cahill notes a post on Digital Bond blog where Dale Peterson analyzes Emerson’s Ovation for security. Jim consults his experts (hence, Emerson Process Experts blog title) and provides a balanced look at security.
I had a brief exchange with Peterson a month or two ago where he was ripping magazines a little. In one response, he was critical of us in the media for not ripping suppliers–for instance, we should have been publicly chastising Siemens for permitting Stuxnet. I like Jim’s response in general about the need for defense in depth and the fact that threats change on a daily basis. Certainly in a perfect world suppliers would foresee all possible threats and provide a bulwark agains them. But, it’s not a perfect world. Due diligence is probably the best we can ask.
