Axians guides on OT vulnerability management in industrial processes
Axians has released guidance on managing operational technology (OT) vulnerabilities and their impact on industrial processes, aiming to enhance the security of critical infrastructure.
Axians, a company specializing in IT and technology services, has published a comprehensive guide detailing the management of operational technology (OT) vulnerabilities within industrial settings. The guide emphasizes how identifying and managing vulnerabilities in OT environments is crucial for ensuring the security of industrial processes, critical infrastructure, and even environmental safety.
According to a report, nearly three-quarters of global companies have experienced a cyberattack on their OT environments. Axians stresses that without a thorough understanding of their specific OT vulnerabilities, businesses remain susceptible to attacks. Commonly identified vulnerabilities include issues with IT system interoperability, outdated software and systems, insufficient network segmentation, and insecure remote access.
The guide also outlines significant differences in managing IT versus OT vulnerabilities. While IT environments prioritize data security and confidentiality, OT environments place primary importance on the availability and safety of physical processes, as disruptions can lead to severe consequences.
Axians highlights that patching in OT environments requires careful planning and testing to avoid costly operational downtime. Unlike IT systems, which often employ automated patching, OT systems may necessitate manual validation and manufacturer approval for updates.
The guide further discusses risk assessment for OT systems, focusing on ensuring the continuity and safety of physical processes, alongside various regulatory requirements like the NIS Directive and the IEC 62443 standard governing the protection of critical infrastructure.
