@TXOneNetworks You guys have better marketing collateral than any vendor I've ever seen. Clear. EAsy to read for an old grumpy man, and is to the point........Maybe I should take that lunch from your fella who keeps ringing me.
THIS. IS. ME. Barbara always encourages me as well.
@Secure_ICS_OT Right?! Although if they keep bringing me these damn delicious lunches, I may take on the headache
I told the SBOM vendor: You’ve successfully turned a functional system into a liability report. I don't need a list of 500 "vulnerabilities" in software I didn't write. I need the machine to run w/o hitting a safety trip because some scanner thinks a legacy library is "unsecured"

Barbara asked what I want for Father's Day. I said "a day where nobody sends me a LinkedIn message about IT/OT convergence." She said "be realistic." I said "fine. New channel locks." Everyone's happy. Marriage is about compromise.
I have three rules for the weekend: 1. The lawn gets mowed before 9 AM. 2. The Budweiser doesn't get opened before noon. 3. Nobody says the words "cloud," "AI," or "quick call" in my house.
✂️ Isolation saves time. Map clean “cut points” to separate OT from business/third‑party networks during a cyber event. The #CIFortify hub shows how to do it safely. Start here: cisa.gov/fortify
@CISAgov "must be able to isolate vital systems from harm"... I've only been saying this for 20 years. If we don't plug it in to the internet, how can it be hacked? How about some credit? TIA - Bobby
@angryolditpers1 Actually updated this one. Even though it worked perfectly.
IT kid tried to install "security agents" on the HMI for the #2 turbine. I told him if that SOB lags for even a millisecond bc of a background update, he’s coming out to the floor to explain to the plant manager (Buck) why we’re losin his yearly salary an hour. #OTSecurity
Freaking @Claroty. I love some of you guys, but you have to be the most bandwagon vendor out there. Heads up...@nozominetworks is nearly 10 years ahead of you with ai. And @nozominetworks don't think you're getting off unscathed...New day tomorrow.
Some rep tried to tell Jerry my refusal to update the PLCs was just "legacy thinking." Jerry said,"Bob is the only reason this plant hasn't had a safety trip since 93." Play me against the CISO & you’re gonna lose. Jerry’s got a fancy desk now, but he still respects the floor.
Monday morning: The blower is screamin, the coffee is bitter, and the IT guys are talking about "digital transformation." I’m just trying to make it to lunch without a hardware failure. 🛠️☕️ #MondayBlues #OTLife
A GREAT example of the potential severity differences between a breach on your email server or a control system. "Hate your emails stopped sending....BUT DID YOU DIE?" **Everyone was safe and this wasn't a hack that I know of....Point remains the same.
A terrifying roller coaster rescue is underway in Galveston, Texas Thursday. A car became stuck on a vertical track, leaving eight people dangling at the very top of the ride. Firefighters are using a long-ladder truck to reach the riders several stories above the ground. Crews
We naming software like it’s a new hire now? @Claroty Claire sounds like she should be organizing the tool crib, not running "mission-critical infrastructure." If I see an "AI agent" trying to optimize my legacy boilers, I’m pulling the main breaker. 🔌👊 #OTSecurity #PlantLife

@Claroty Side note...I knew a brunette named Claire before I met Barbara..... Let's just say, she was similar to a 7-11 or Waffle House. "ALWAYS OPEN" and "EASILY COMPROMISED"
@Claroty Claire? Unless Claire can pull a double shift in 105-degree heat and tell why the pump is rattling just by listening to it, I don't need her "agentic action." I’ve got Big Dan. He doesn't have an algorithm, but he has a 10lb sledgehammer. 🛠️ #AI #OTSec
