Automation can't replace human oversight: A cybersecurity story

Patching in production without testing is asking for trouble. But many OT environments still lack even basic test environments. We help clients mirror key configurations or build digital twins—so they can patch with confidence, not crossed fingers.

Manual Patching vs. Automated Patch Management – What’s Safer? In cybersecurity, patching is your first line of defense like fixing a leak before it sinks the boat. The real question: Manual or Automated? 🔹 Manual Patching Full control over updates Thorough, environment-specific testing Lower risk of software conflicts 🔹 Automated Patch Management Rapid deployment closes gaps faster Consistent, repeatable process Frees IT teams for strategic work 💡 Best Choice? Often, a hybrid model automates routine updates, manually tests critical ones, and uses monitoring with rollback plans. The biggest risk isn’t the method it’s delaying patches. #CyberSecurity #PatchManagement #ITSecurity #Automation #Cybosecure

Day 27: Patch Management: Automation vs. Control One of the biggest challenges in enterprise security is keeping systems patched without disrupting operations. Manual patching gives IT full control, but it is slow, inconsistent, and costly. Full automation drives efficiency, yet creates fear of breaking critical systems. The sweet spot is controlled automation: Automate critical and high-severity patches daily. Schedule medium and low-severity patches within standard cycles. Use “test before deployment” on a small set of devices before rolling out patches organization-wide. Keep rollback-ready versions available to reduce risk if something goes wrong. This approach reduces vulnerability exposure, maintains uptime, and gives both security and IT teams confidence in their processes. Cybersecurity isn’t about choosing between speed and safety. It’s about designing processes where both coexist. #CyberSecurity #PatchManagement #VulnerabilityManagement #InfoSec #RiskReduction #Automation #CISO #SecOps

🚨 Reactive security is risky. Proactive security is powerful. In today’s world, waiting for a cyber threat to strike just isn’t an option anymore. What I liked about this video is how clearly it shows the benefits of staying ahead of risks instead of reacting after the damage is done. A few takeaways that stood out for me: 🔹 It’s not only about ticking compliance boxes—it’s about real, continuous protection. 🔹 Automation takes away the heavy lifting and gives peace of mind. 🔹 Security workflows don’t have to be complicated—they can be streamlined and effective. Being proactive means: ✔️ Shrinking your attack surface. ✔️ Always being audit-ready. ✔️ Freeing up your team’s time to focus on what matters most. 👉 Watch the video here: https://lnkd.in/dwzqXKJJ #CyberSecurity #ProactiveSecurity #Compliance #BusinessResilience

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

🚨 NIDS Rule Creation and Testing Lab — Project Completed Over the last four weeks, our team set up and tested a complete Network Intrusion Detection System (NIDS) using Snort in a controlled lab environment. Here’s the thing, building a lab wasn’t just about getting Snort to run. We wanted to actually simulate real-world attacks, write our own detection rules, and see if the system could catch them in real time. Lab setup: Two VMs on a private, isolated VMware network Attacker machine running Snort with tools like Nmap and Hydra Target machine running vulnerable services (SSH, FTP) What we did: Installed and configured Snort with custom rules for ICMP traffic and SSH brute-force detection Simulated attacks like port scans and brute-force attempts Validated rules through console monitoring and log analysis Collected performance metrics to see how the system handled everything Key results: 100% detection rate across all simulated attacks Zero false positives Real-time alerts with sub-second response times Minimal system resource usage, meaning detection didn’t slow down the environment Why this matters: This project wasn’t just about running commands. It taught us how to design, test, and validate intrusion detection in a way that mirrors real-world security operations. From writing detection rules to analyzing alerts, we got hands-on with the kind of work security analysts actually do. Team: Meka Sharanya, Oishika Chakraborty, Md Shahbaz Supervisor: Vasudev Jha Big takeaway? Intrusion detection isn’t about installing a tool and walking away. It’s about constantly testing, refining, and validating rules against live traffic. That’s the only way to trust the alerts when it matters.

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 (ICSA-25-226-25) has been issued by CISA regarding Rockwell Automation’s Micro800 controllers. The vulnerability stems from a compromised third-party component, carrying a CVSS score of 9.3 – meaning it’s remotely exploitable with low attack complexity. ⚠️ This highlights the increasing risk surface created by software dependencies within industrial control systems. It’s a good reminder that security isn’t just about the core product, but also the integrity of *everything* it relies on. Organizations using Micro800 controllers should review the advisory immediately and apply available patches. Prioritizing vulnerability management in OT environments is more critical than ever. Anyone else grappling with similar supply chain security challenges in their ICS deployments?
