How to Secure Your Industrial Control Systems

Industrial Control System Cybersecurity. How Industrial Leaders Can Build Cyber Resilience. Learn about our practical, lifecycle-based approach to OT cybersecurity for industrial control systems (ICS) — built around a consultative partnership, phased implementation and measurable improvement.

Relying on a single security solution is like locking one door in a building full of entrances. For SMBs, defense in depth is no longer optional—it's essential. This post breaks down what multilayered cybersecurity really means and why it matters more than ever. 🔗 Link in first comment

https://lnkd.in/gYDredcT The latest report shows a sharp rise in internet-exposed OT/ICS devices to be over 200K now visible each month. Raising serious concerns for operational safety, continuity and cyber resilience. #OTsecurity #ICScybersecurity #OTcyber #IndustrialControlSystems #ZeroTrust #DefenseInDepth #CriticalInfrastructure #ManufacturingSecurity #CyberResilience #IIoTsecurity

ℹ️ #NIST publishes guide for protecting #ICS against USB-borne threats Removable media such as USBs and external #digitalstorage drives may seem harmless... but in #OT and ICS environments, they can open gateways to severe disruption. The recent National Institute of Standards and Technology (NIST) guide highlights how these devices pose real danger to #criticalinfrastructure when controls are weak. At Arista Cyber, we help organizations apply proactive #cybersecurity measures across industrial networks to close such risks before they become incidents. ✔️ Establish trusted device policies and enforce strict access ✔️ Apply technical controls i.e. port disabling, malware scanning, and write-protection ✔️ Embed continuous monitoring and personnel training to reduce exposure 🛡️ When physical systems depend on digital entry points, visibility and vigilance are non-negotiable. NIST Special Publication 1334 focuses on reducing cybersecurity risks associated with the use of removable media devices in OT environments. Read the full guide: 🔗 https://lnkd.in/gPFhs2Yc

Understanding what’s “normal” in your OT environment is one of the most powerful ways to strengthen cybersecurity. In his latest EmberOT guest article, Rishabh Das, Ph.D. explores how to build and maintain baselines that define normal behavior in industrial systems, and how those baselines help teams detect threats faster and respond with confidence. He outlines practical steps for: - Identifying and inventorying OT assets - Establishing a baseline of normal communication and behavior - Detecting and responding to deviations that could indicate risk Read the full guide to learn how baselining transforms OT visibility and resilience: 🔗 https://lnkd.in/gx8Jaf2d

What is Unified Defense? It’s an integrated approach to security that connects people, processes, and technology — breaking down silos between cyber, physical, operational, and personnel security. In today’s interconnected threat landscape, smarter defenses start with unity.

Protecting patient data and critical systems requires more than isolated cybersecurity tools — it demands a Unified Defense. Nortal’s approach brings together technology, people, and processes to create secure, connected, and resilient healthcare ecosystems. 

We don’t face “cyber” problems or “physical” problems—we face business risks. That’s why Unified Defense matters: one playbook, shared signals, faster response. Great overview here.

Regulatory agencies are stepping in to ensure the protection of pipeline systems, mandating cybersecurity standards that call for an integrated approach to IT and OT security. Why? Because as these systems rely more heavily on internet-connected devices and automation, the risk of cyber threats continues to grow. Implementing layered security measures isn't just a best practice—it’s essential to safeguarding the stability and safety of our critical energy infrastructure.
