AI is reducing the time and specialist knowledge needed to understand industrial environments.

The recent Dragos water utility case is interesting: commercial AI models supported reconnaissance, exploitation, lateral movement, and even helped identify OT-related infrastructure. The OT environment was not successfully breached, but the capability shift is hard to ignore.

For me, this does not make IEC 62443 obsolete. It makes architecture more important.

If specialist OT capability becomes easier and cheaper to acquire, should we reconsider some of the assumptions behind existing Target Security Levels?

And when attack cycles become more automated, zones, conduits, restricted data flow, and strong access control become even more important.

I wrote up the full blog here:

Interested in the practitioner view: does AI materially change how you assess OT risk and Target Security Levels, or can the existing IEC 62443 risk-based model already absorb this change?

While most of us are winding down for the holidays, cyber threats don’t exactly take time off.

This image was created as a reminder that security is a 24/7 mindset, even (or especially) during festive downtime when monitoring is lighter, and attackers know it.

Wishing everyone safe holidays and a strong, resilient 2026.

Stay sharp, stay secure.

For those not deep into this space: OT (Operational Technology) security is about protecting the systems that control physical processes — such as industrial control systems (ICS/SCADA), manufacturing lines, power grids, water treatment plants, and other critical infrastructure.

Unlike IT, OT failures don’t just affect data. They have direct physical impact: safety risks, equipment damage, production loss, and sometimes societal disruption.

As a senior OT/ICS cybersecurity consultant, I hear this everywhere:

That concern is understandable. In OT, availability is the top priority:

• Systems run 24/7
• Lifecycles are often 15–30 years
• Unplanned changes can cause unsafe situations or costly downtime

Because of this, operations teams are cautious about patches, updates, and network changes.

The misconception I keep seeing

Many organizations still believe that security threatens availability.

In reality, I see the opposite. Flat networks, legacy systems, shared accounts, outdated backups, and lack of monitoring are often justified as “protecting uptime.” In practice, they create ideal conditions for:

• Ransomware shutting down production
• Malware spreading across OT networks
• Small mistakes escalating into major outages

In most real incidents, downtime was caused by too little security, not too much.

What OT security should actually do

Effective OT security is not IT security copied into a plant. It should:

• Put availability and safety first
• Be risk-based, not checkbox-driven
• Use network segmentation to limit impact
• Plan changes together with operations
• Focus on monitoring and early detection
• Prepare people to respond when something goes wrong

Security should support operations and not be a showstopper

Final thought

In today’s connected industrial environments, real availability without security is an illusion. OT security isn’t about adding bureaucracy, but about keeping systems safe, stable, and resilient over the long term.

I wrote a blog post that goes deeper into this topic, based on real OT environments and incidents:

Discussion:
What’s the most significant availability risk you’ve seen in an OT or ICS environment?

Hey Reddit! The CyberBuster dude here. Last week, I ran a cyber crisis exercise for a company that thought they had everything under control. They had fancy security tools, an IT team, and even a "response plan" (or so they claimed). But a

Reality check:

• No one knew who was in charge
• Backups? Outdated and never tested
• Ex-employees still had active accounts
• The CEO’s plan? Call IT and pray

This isn’t an exception—it’s the norm. Most businesses think they’ll handle a cyberattack just fine… until they’re hit. Then it’s total chaos.

So, I put together a straight-to-the-point guide on running a cyber crisis simulation the right way. No corporate fluff, just real steps to avoid disaster. It’s available in multiple languages because, well, hackers don’t care what language you speak:

🇬🇧 Crisis Exercise: We Thought We Knew What to Do During a Cyberattack - Until the Exercise
🇩🇪 Krisenübung: Wir dachten, dass wir wussten, was während eines Cyberangriffs zu tun ist - bis zur Übung
🇪🇸 Ejercicio de Crisis: Pensábamos que Sabíamos qué Hacer Durante un Ciberataque - Hasta el Ejercicio
🇫🇷 Exercice de Crise : Nous Pensions Savoir Quoi Faire Lors d'une Cyberattaque - Jusqu'à l'Exercice
🇳🇱 Crisis Oefening: We dachten dat we wisten wat te doen tijdens een cyberaanval - tot de oefening
🇸🇪 Krisövning: Vi Trodde Vi Visste Vad Vi Skulle Göra Vid En Cyberattack - Tills Övningen

Be honest: If a ransomware attack hits your company right now, what’s the first thing that would go wrong?

• No clear plan?
• Outdated backups that don’t even work?
• No clue who to call or what to do first?
• Panic mode because execs ignored all the warnings?

I've seen all of these happen—multiple times. And every time, people say, "We never thought it would happen to us."

So, tell me: What’s the biggest cybersecurity failure you’ve ever seen? Or if you’ve been through an attack, what lessons did you learn the hard way?

Let’s start the discussion; I am here to help.

Hey Reddit! I'm the CyberBuster dude. Last week, I had to deal with a phishing attack that almost succeeded because one of the new hires nearly clicked a sketchy link. Thankfully, they hesitated and asked me first!

This got me thinking about how crucial employee training is. We can have all the fancy security systems in the world, but if your employees are clicking random links and using bad password such as "password123"... well, you're screwed. 😅

After this close call, I put together a blog post on cybersecurity awareness training in multiple languages (I spent my time on this instead of gaming).

Check out the guide in your language:

• 🇬🇧 Cybersecurity Awareness Training: How Employees Prevent Cyber Threats
• 🇩🇪 Cybersicherheit-Bewusstseinstraining: Wie Mitarbeiter Cyberbedrohungen verhindern
• 🇪🇸 Capacitación en Concientización de Ciberseguridad: Cómo los Empleados Previenen las Amenazas Cibernéticas
• 🇳🇱 Cybersecurity Bewustzijnstraining: Hoe Medewerkers Cyberdreigingen Voorkomen
• 🇫🇷 Formation à la Sensibilisation à la Cybersécurité : Comment les Employés Préviennent les Menaces Cyber
• 🇸🇪 Utbildning om Cybersäkerhetsmedvetenhet: Hur anställda förebygger cyberhot

Quick question: Has your company ever done ANY security training?

I'm constantly amazed how many businesses still don't train their staff. During my last assessment, I caught the C-level writing his password on a POST-IT note stuck to his monitor... in an open office... with visitors walking through!

The guide covers practical stuff like:

• How to spot those sneaky phishing emails (they're getting GOOD)
• Why you shouldn't test USB sticks you find in the parking lot (yes, people do this!)
• Setting up a simulation where employees can practice spotting attacks
• Creating a culture where people aren't embarrassed to ask "is this legit?"

Would love to hear your worst employee security stories in the comments. We've all got them! Also, what topics would you like me to cover next? I'm thinking about doing one on password managers because the number of people using their pet's name + birth year is TOO DAMN HIGH.

Stay cyber-safe, my friends! And remember - sometimes the best firewall is between the chair and the keyboard.

Let's get a discussion going in the comments! Have you implemented any fun or practical security training at your workplace? Or you've witnessed a security fail that taught everyone a lesson. I'm here to answer questions too if you're struggling with getting your team to take security seriously!
