Industrial Cyber Risk: A Pragmatic Approach to OT Security

Protecting OT/SCADA environments starts with a solid foundation. The Purdue Model still remains a proven framework for securing OT/SCADA environments by segmenting industrial networks into logical layers of trust and control. Here are the key fundamentals: - Segment IT from OT: Create a clear boundary between your enterprise and industrial networks to prevent threats from crossing over. - Limit east-west traffic: Control communication within and between OT layers to minimize the lateral movement of threats. - Apply strict access controls: Enforce strong authentication and authorization policies at every layer to ensure only authorized users and devices can access critical systems. - Monitor continuously: Implement continuous monitoring to detect and respond to anomalies and potential threats in real time. The Purdue Model is a strong starting point, but it should be combined with modern OT security practices like Zero Trust, secure remote access, and continuous threat monitoring to stay effective against today’s threats. How is your organization applying these principles to protect your industrial networks? #OTsecurity #PurdueModel #SCADA #ICS #Cybersecurity #NERC-CIP

Ransomware incidents on critical infrastructure are on the rise. Factories, power grids, and water plants have become prime targets for cyberattacks. From legacy systems and supply chain vulnerabilities to IT/OT convergence, securing operational technology (OT) has never been more critical. Our latest blog highlights 7 best practices organizations can adopt to strengthen resilience. ✓ Building security into OT by design ✓ Enhancing collaboration between IT & OT teams ✓ Continuous threat monitoring and response Read the full insights here: https://bit.ly/4mvUaVa Azeem Aleem #CyberSecurity #OTSecurity #CriticalInfrastructure #Resilience #ThreatIntelligence #DigitalTrust #CPX

Ransomware attacks on critical infrastructure are no longer hypothetical—they are happening now, and their impact can be devastating. At CPX we see firsthand how the convergence of IT and OT has created new opportunities for innovation but also new vulnerabilities. Protecting factories, utilities, and essential services requires more than just traditional defenses. It calls for a mindset shift: building security into OT by design, bridging the gaps between IT and OT teams, and adopting a proactive, always-on approach to threat monitoring and response. I encourage industry leaders to read our latest blog, where we share 7 practical steps to strengthen #resilience and #safeguard critical operations: https://bit.ly/4mvUaVa

Three years in the Shadows! That’s how long an adversary silently lived inside a critical environment we investigated—carefully mapping systems, moving laterally in stealth, and assessing every pathway before preparing for a ransomware attack. This isn’t an anomaly. It’s a reminder of how patient and methodical threat actors can be when targeting critical infrastructure. They don’t just exploit vulnerabilities—they invest the time to deeply understand environments, ensuring that when they act, the impact is maximized. For defenders, the lesson is clear: resilience isn’t built in the moment of crisis. It’s built over time—through visibility, collaboration, and security woven into every layer of operational technology (OT). Ransomware attacks on factories, power grids, and water plants are rising. Legacy systems, supply chain risks, and IT/OT convergence only widen the attack surface. Protecting OT requires more than tools—it demands culture, design, and constant vigilance. Our (CPX) Latest blog outlines 7 best practices to strengthen OT security, from building security into design to continuous monitoring and IT/OT alignment. It’s not just guidance—it’s a blueprint for staying ahead of adversaries who have all the time in the world. Arnaud R.Juan Pablo Betancourt

🚨 Top 3 OT Security Threats in 2025 🚨 Operational Technology (OT) is the backbone of industries — from power grids to manufacturing plants. But with rising cyberattacks, OT security has become more critical than ever. Here are the biggest threats to watch in 2025: 1️⃣ Ransomware targeting critical infrastructure 2️⃣ IT & OT convergence risks 3️⃣ Insider threats & human error 🔒 Securing OT is no longer optional — it’s essential for keeping factories running, lights on, and cities safe. 💡 What do you think will be the biggest OT security challenge in the coming years? #OTSecurity #CyberSecurity #CriticalInfrastructure #IndustrialCyberSecurity #Industry40 #ITOT #Ransomware #ICS #SCADA

In today’s evolving threat landscape, quick containment and strategic isolation are crucial. A Defensible Cyber Position enables organizations to rapidly strengthen and isolate their digital ecosystems during #CyberIncidents, maintaining only essential operations to minimize damage and keep critical processes running. Originating in industrial control systems, this approach now spans all sectors—from finance and healthcare to manufacturing. Real-world examples like Maersk’s response to NotPetya and Colonial Pipeline’s proactive OT shutdown highlight how swift, pre-planned actions can drastically reduce impact. Whether it's disconnecting IT from OT or switching to manual control, preparation and security testing are significant. The path to robust #CyberResilience involves tailored controls, industry-specific strategies, and continuous testing, thereby ensuring your organization can “fight through” an attack without total shutdown.

💡 On the factory floor, the biggest risks extend beyond mechanical issues; they include digital threats as well. Cyber resilience involves more than just implementing firewalls and using strong passwords. It requires integrating adaptability, rapid response, and continuity into every process to keep production running smoothly. In today's interconnected world, downtime is not only expensive; it poses a significant threat to competitiveness. Read the article in Industry Today to discover how manufacturers can reinforce resilience in the most critical areas. https://lnkd.in/ggx4Rz-6

Simulate to Secure – Why OT Simulation is Critical for Cyber Resilience Simulation is a proactive part of the OT risk assessment process. By replicating control systems in a secure test environment, organizations can simulate cyberattacks, system failures, or human errors. This approach uncovers hidden vulnerabilities, helps design and validate recovery plans, and equips incident response teams to act swiftly under pressure. Instead of flying blind, simulation turns unknown risks into measurable insights, strengthening overall resilience. At Shieldworkz, we enable organizations to transform simulation into a strategic advantage, improving security posture and compliance.

🚨 When a cyber attack strikes… what happens next? That’s where Incident Response (IR) comes in. Every organization needs a solid IR plan — not having one is like fighting a fire without water. 🔑 Phases of Incident Response: 1️⃣ Preparation – Define policies, train teams, run simulations. 2️⃣ Detection & Analysis – Spot the incident, confirm it’s real. 3️⃣ Containment, Eradication, Recovery – Stop the spread, remove the threat, restore systems. 4️⃣ Lessons Learned – Review what failed, improve defenses. 👉 IR is not just about fixing damage, it’s about building resilience. ❓Do you think most companies actually test their IR plans or just keep them on paper? #CyberSecurity #IncidentResponse #InfoSec #BlueTeam #CyberResilience
