How to Patch in OT without Risk: Digital Twins and Test Environments

Industrial cybersecurity isn’t just about tech! The real challenge? IT, OT, integrators, and suppliers often don’t speak the same language. Different priorities, different terms… lots of room for confusion.   That’s why ISA/IEC 62443 starts with Part 1-1. No controls, no tools—just concepts and a common vocabulary so everyone’s on the same page.   💡 Why it matters 📍 Even the best strategy fails if people can’t understand each other. Shared language = fewer misunderstandings = stronger security.   If you’re new to 62443, start with Part 1-1. It won’t give you a checklist of controls, but something even more powerful: clarity.   #IEC62443 #OTSecurity #IndustrialCybersecurity #ITOTAlignment #CyberResilience

IEC 62443-1-1 lays the foundation for industrial cybersecurity. It defines common language, zones & conduits, and a risk-based approach essential for any OT security strategy. #CyberSecurity #OTSecurity #IndustrialCybersecurity #IEC62443 #RiskManagement

A critical security advisory from CISA highlights vulnerabilities in the Rockwell Automation Micro800 controller. The alert (CVSS v4 9.3) details risks stemming from vulnerable third-party components and improper input validation—potentially allowing for remote exploitation. 🚨 This impacts industrial control systems, so patching and mitigation are key for operations relying on this technology. It’s a good reminder of how supply chain security is paramount in OT environments; vulnerabilities aren't always within your own code. ICS teams should review the advisory details and assess their exposure. Prioritizing vulnerability management across all system layers—including dependencies—is crucial for robust security.

Production lines create unique ransomware challenges most security assessments miss. OT/IT convergence means your manufacturing systems are increasingly connected to business networks. But industrial control systems weren't designed with cybersecurity in mind. The scary reality: Many HMI systems run outdated Windows versions Production networks often lack basic security monitoring Operational staff may not recognize cybersecurity threats Downtime costs can exceed $100,000 per hour A ransomware attack doesn't just encrypt files – it can halt entire production operations. Manufacturing ransomware readiness requires specialized assessment of both business systems and production environments. #ManufacturingCybersecurity #IndustrialSecurity #ProductionSecurity #OceanSolutions Protect your production: https://hubs.la/Q03DVtfF0

DoD organizations face a choice in meeting DISA STIG requirements: rely on manual scripts and checklists or adopt automated compliance solutions. Legacy methods are slow, error-prone, and hard to scale, while automation reduces manual effort, delivers results in hours or days, and ensures continuous audit readiness. Knowing the difference is key to strengthening security while saving time and resources. #STIGeasy #STIGwithSteelCloud #YourSTIGWingman #Automation #DoD #Compliance #Cybersecurity

Legacy vs. Modern STIG Compliance, the difference is clear: Legacy = manual effort, delayed remediation, reactive audits Modern = automation, continuous monitoring, always audit-ready SteelCloud’s ConfigOS MPO is designed to take STIG compliance from a burden to a force multiplier by streamlining updates, accelerating remediation, and scaling across even the most complex environments.

Most OT attacks exploit misconfigurations, weak authentication, or long-known vulnerabilities that were never patched. Attackers know that operators often assume "if it isn’t broken, don’t touch it"—and that mindset leaves doors wide open. The truth: securing PLCs isn’t just about chasing the next zero-day. It’s about tightening the basics—access controls, network segmentation, monitoring, and timely response. #100DaysOfOTCybersecurity #OTSecurity #PLC #CyberRisk #ICS

Secure by Demand... Priority considerations for OT asset owners and operators Here is a document listing Priority considerations for OT owners and operators when selecting digital products CISA and partners warn that cyber threat actors, when compromising OT components, target specific OT products rather than specific organizations. Many OT products are nt designed and developed with Secure by Design principles and commonly have weaknesses such as weak authentication, known software vulnerabilities, limited logging, insecure default settings and passwords, and insecure legacy protocols. When security is not prioritized, nor incorporated directly onto OT products, it is difficult and costly for owners and operators to defend their OT assets against the compromise.  This secure by demand guide authored by CISA with contribution from many partners describe how OT owners and operators should integrate security into their procurement process when purchasing industrial automation and control systems as well as other OT products.  #cybersecurity #otsecurity #icssecurity #securebydesign #risk

Don't Let IT Manage Your OT Assets Alone! Treating your OT assets like IT is a major risk. While IT focuses on data, OT's top priorities are safety and uptime. IT teams, unfamiliar with industrial systems, may not understand the critical risks of applying a patch that could shut down a factory or create a safety hazard. OT environments use specialised hardware and legacy software that require a different approach to maintenance and security. For true resilience, IT and OT teams must collaborate. Combining IT's security expertise with OT's operational knowledge is the only way to protect your physical infrastructure and ensure continuous, safe operations. Your factory floor is not a server room - don't manage it like one. #OTSecurity #Obsolescence #CyberSecurity #ICS #SCADA
