🔐 IT/OT Connectivity: Expanding the Cyber Attack Surface for ICS 🔐 The integration between IT and OT environments has widened the cyber-attack surface for ICS networks. 🚨 In power distribution companies, threat actors can infiltrate the OT environment through the IT network, potentially gaining unauthorised access to SCADA/HMI and executing damaging actions. 🛡 To protect critical infrastructure, it's crucial to define robust and resilient countermeasure strategies, including: 1. Risk measurement and mitigation planning. 2. Implementing layered security controls. 3. Continuous control testing: integration, access, and exploring attack vectors to refine countermeasures. Securing ICS systems to ensure safety and reliability is of utmost importance. #CyberSecurity #ITOT #ICS #SCADA #CriticalInfrastructure #CyberResilience #CyberAwareness #ControlTesting

Since I work across multiple verticals — including energy and transportation — I tend to identify parallels between industries and the problem-solving techniques employed in one that are transferable to another. This GAO report, while focusing on industrial cybersecurity (specifically pipelines), offers insights into tools, frameworks, and methodologies that are equally applicable to Intelligent Transportation Systems (ITS). Adapting these recommendations can enhance ITS security against cyber threats, safeguarding connected vehicular environments and boosting network resilience and efficiency. Notably, as CISA investigates the Key Bridge incident, any confirmed cyberterrorism links could profoundly impact connected systems. #cybersecurity #operationaltechnology #intelligenttransportationsystems #its #connectedvehicles #gaoreport #infrastructuresecurity #cisa #cyberthreats #transportationsecurity

Why is OT cybersecurity in energy so challenging? Unlike IT, OT security has to prioritize physical safety and operational continuity. Here’s how OT security differs and why it matters 👇 In IT, cybersecurity is primarily about protecting data. But in OT (Operational Technology), it’s about safeguarding the infrastructure that directly controls critical operations, from pipelines to power grids. A cyber incident in OT could disrupt essential processes or even endanger lives, as we saw in the 2021 Oldsmar water plant hack, where attackers attempted to manipulate water chemical levels. However, securing OT environments isn’t straightforward. These systems often run on legacy technologies that are limited in their ability to perform frequent updates, have strict uptime requirements, and were not initially designed with cybersecurity in mind. To address these unique challenges, OT cybersecurity strategies focus on: 1️⃣ Real-Time Monitoring: Detecting issues before they escalate. 2️⃣ Network Segmentation: Isolating critical systems to minimize exposure. 3️⃣ Lifecycle Management: Balancing system age and availability needs with modern security practices. In short, unlike IT, OT cybersecurity must prioritize continuous operations and safety, making protection strategies complex yet essential.

When connectivity and cybersecurity are both essential. A fascinating, and thought-provoking, white-paper from Advantech which offers insights into the complex area of #TSN (time sensitive networking) and provides solutions for overcoming the challenges posed by balancing real-time communication with a growing need for fortifying systems against cyber threats. Drawing upon the specific requirements of intelligent transportation systems, the energy & utility sectors and developments within both maritime and factory automation applications, the integration of TSN with robust cybersecurity protocols is essential for protecting critical infrastructure against evolving threats. #cybersecurity #TSN #digitaltransformation #apctechnologyltd #IEC62443 #TS50701 #CNI #realtimecommunication #energysector #utilitysector #maritimesecurity

Much of the nation's #criticalinfrastructure relies on #OT—systems that interact with the physical environment—to provide essential services. However, malicious cyber actors pose a significant threat to these systems. Federal law designates #CISA as the lead agency in helping critical #infrastructure owners and operators address #cyber risks to OT. The National Defense Authorization Act of Fiscal Year 2022 includes a provision for GAO to report on #CISA's support for industrial control systems. Federal guidance now addresses these systems under the broader category of OT. Accordingly, this report examines, among other things: (1) challenges in delivering CISA's OT products and services, and (2) challenges to collaborating between CISA and the seven selected agencies. GAO reviewed documentation describing CISA's 13 OT cybersecurity products and services. GAO also asked officials from CISA and 13 selected nonfederal entities to identify any challenges with the OT products and services. The selected entities included (1) councils representing one sector and three subsectors where OT was prevalent and the intelligence community highlighted their infrastructures as being at risk from cyber threat actors, (2) OT vendors who joined a CISA OT collaboration group, and (3) cybersecurity researchers that contributed to the development of CISA's OT advisories. GAO then compared CISA's efforts to address those challenges against leading practices regarding measuring customer service and workforce planning. Write up: https://lnkd.in/gsRi4ama

Industrial communication protocols play vital role in securing industrial communication system As they considered as neural network to transfer data between different cyber assets . Most of industrial communication protocols designed to be reliable , not to be secure which make it vulnerable for unauthorized modification that could affect #integrity and #availability of #ICS .  System security requirements SR 3.1"Communication integrity " in ISA/IEC 62443-3-3 emphasize on importance of industrial communication protocols in securing ICS To safeguard the critical infrastructure, it's essential to understand the protocols used in ICS network.

The Importance of Zero Trust in Operational Technology (OT) 🏭 Operational Technology (OT) environments, such as those in manufacturing, energy, and critical infrastructure, are increasingly becoming targets for cyberattacks. In 2021, over 90% of manufacturing organizations reported cyber incidents impacting their operations. Breaches in OT can have severe consequences, including production stoppages, safety risks, and substantial financial losses. As OT systems become more integrated with IT networks—a trend known as IT/OT convergence—the vulnerabilities grow, making the implementation of Zero Trust crucial for protecting these critical systems. Core Principles of Zero Trust for OT 🛡️ Never Trust, Always Verify: Continuous verification of users and devices is essential. Access should be granted based on real-time assessments rather than static credentials. Least Privilege Access: Users and devices should have only the minimum access necessary to perform their functions, limiting potential damage from compromised accounts. Micro-Segmentation: Network segmentation is vital for creating isolated environments for different OT components. This approach minimizes lateral movement within the network by restricting access based on specific policies tailored to individual resources. Continuous Monitoring: Real-time monitoring and threat detection capabilities are crucial for identifying anomalies that may indicate a breach. Advanced analytics can enhance this process by providing insights into network behavior. #IndustrialCybersecurity #OTSecurity #CriticalInfrastructure #zerotrust
