Why Mapping Your OT Networks Is the Pillar of Industrial Cybersecurity?
Industrial cybersecurity is a major concern for companies. Cyberattacks can have disastrous consequences on equipment, processes, and critical company data. To effectively protect against these threats, mapping Operational Technology (OT) networks has become an essential pillar of industrial security. This article explains why.
What is OT Network Mapping?
OT network mapping is the practice of identifying and documenting all equipment, software, protocols, and connections that make up a company’s OT system. This mapping provides a comprehensive view of the network, helps understand how different elements interact, and enables the detection of anomalies or suspicious activities.
Why OT Network Mapping Is Essential for Industrial Cybersecurity
Understanding Vulnerabilities
Mapping the OT network allows companies to better understand system vulnerabilities. By identifying all weak points in the network, companies can take measures to strengthen them, thereby reducing the risk of attacks. Network mapping also helps detect conflicts between different equipment and processes, which could potentially cause malfunctions or downtime.
Managing Updates and Security Patches
OT network mapping improves the management of updates and security patches. With a complete overview of the network, companies can easily identify which devices need updates and apply them efficiently. This minimizes production interruptions and ensures updates are consistently implemented across the entire network, strengthening overall system security.
Understanding Equipment and Process Interactions
Mapping OT networks helps companies better understand interactions between different equipment and processes. With this knowledge, they can anticipate the potential impact of changes made to OT infrastructure. This allows for additional security measures to prevent production interruptions or critical system failures.
Detecting Threats and Suspicious Activity
Finally, OT network mapping is crucial for detecting potential threats and suspicious behavior on the network. By monitoring application flows and comparing normal traffic patterns to those observed, companies can quickly identify anomalies and potential attacks. Network mapping also provides insight into system vulnerabilities and the risks associated with each piece of equipment.
