Last week, someone hacked into my wireless router.
No damage was done, since I was back to Phoenix for the weekend as part of my 100,000 mile commute (only 182 days to go – more on that later!).
Nevertheless, I was disturbed because I thought I had set everything up securely and according to the directions included.
Apparently, the default security mechanism for the router was WEP encryption, which uses a fixed encryption code, kind of like the old-style garage door openers. (Read more here)
And since someone had “cracked” the code on my old-style garage door opener to break into our garage and house(!) about 5 years ago, I was a bit more concerned that the neighborhood hacker in my Houston apartment complex might be tracking my every move online, capturing userid’s, passwords, etc to eventually steal my identity. Yikes!
So, like I did for my garage door opener, I upgraded the security mechanism on my wireless router to a rolling-code that regenerates automatically to keep the wannabe thieves out.
>> You might want to check the security mechanism on your home network router and if you’re not already using WPA (for rolling code protection), you should upgrade from WEP tonight.
Why tell the story about WEP and WPA in my blog?
I re-tell this story make a point – that for every good engineer following directions and implementing the automation technologies as suggested by the manufacturers, there is a hacker, a thief, a disgruntled employee, or well-intentioned “help” from non-experts or users with fat fingers (see a prior blog on that) which push the limits of our systems and bring about changes that are not desired or even intended.
And if we’re lucky, the change is noticed and corrected for.
If we’re not so lucky, the change lurks in the background – as a reset constraint value, alarm limit, controller mode or other.
Lurking around until the day when plant conditions require a certain reaction from that specific constraint, alarm or controller – a reaction that is no longer what it should be.
In the process industries, we rely on the automation systems to respond as planned. Plant performance depends on it. Reliability depends on it. As does safety, and our jobs and… our families.
But many of you still operate your plants without being sure of the integrity of their automation systems?
Sure, we followed the directions and configured everything just so when we set up our systems… oh so many years ago. And today we assume all is OK, even as we have made many small adjustments here and there – assuming all is still OK.
But how can we be sure?
By using Integrity – the software from PAS designed to be sure.

Don’t run your plant without it.
Like the comfort of being sure at home, your family depends you being sure at work too.
Remember that when you set your next budget.
