Security monitoring for OT (OT SOC)

Continuous monitoring and detection is one of the requirements of the NIS2 directive. Companies must implement systems for continuous monitoring and detection of security incidents. This includes the use of advanced monitoring tools to detect suspicious activity in real time.

Monitoring OT environments requires a different set of skills and understanding than traditional IT security. To ensure effective detection and response, technology such as IDS, endpoint agents and log analysis, combined with in-depth knowledge of OT processes, functional design and operational information is required.

While IT monitoring often focuses on fast and automatic response, OT monitoring requires high-accuracy alerting and manual evaluation in collaboration with system owners and the OT system integrator.

An accurate alert and response is essential to prevent serious consequences. This means not only informing, but also taking action in close collaboration with system owners and OT system providers.

In addition, control of devices and vulnerabilities (asset inventory) is essential to detect unknown devices in OT environments. Accuracy in alerting and response is therefore critical to maintaining security.

Managed Detection and Response for OT (MDR for OT)

Netsecurity has developed an advanced Managed Detection and Response (MDR) service to effectively detect and manage unwanted activity in industrial systems. Our service is designed to understand the context and criticality of incidents, and alert our customers with the highest possible accuracy.

Technologies and methods we use:

Network detection

Advanced network traffic monitoring to identify suspicious activity

Endpoint detection

Specialized monitoring of OT-related servers and devices

PLC monitoring

Continuous monitoring of programmable logic controllers (PLCs) to ensure the integrity of industrial processes

Log analysis

Deep analysis of log files to uncover potential threats and vulnerabilities

All alarms are collected to our 24/7 SOAR-based Security Operations Center (SOC). Here, the alarms are enriched with documentation from the customer and relevant threat information. Our SOC personnel, who have specialized OT expertise, then carefully evaluate the alarms and work closely with the customer to make the right decisions.

Benefits of OT SOC from Netsecurity

Staffing 24/7: Our SOC is staffed 24/7 to ensure continuous protection
Expertise in OT security: Our experts have in-depth knowledge of OT environments and the unique challenges these systems face
High accuracy in alerting: Alerts are considered in the context of the operational environment to ensure proper notification and response
Close collaboration with customers: We work in partnership with our customers to ensure that all security measures are tailored to their specific needs and environments

What should be monitored?

To ensure optimal monitoring of OT environments, it is crucial to conduct a thorough risk analysis based on the IEC 62443 standard. This involves identifying critical systems to be monitored and determining which detection mechanisms provide the best possible coverage. Together, this constitutes a suitable detection strategy for the monitoring.

We can assist with targeted risk analysis to develop a monitoring strategy tailored to your specific needs .

Our approach includes detailed OT device mapping, threat assessment and strategic planning to ensure your systems are protected from potential threats.

With our expertise in OT security, you can rest assured that your monitoring strategy is both effective and tailored to your unique needs, allowing you to focus on your core business.
