Enhancing security in critical and industrial OT networks with tapping and aggregation solutions
Overcoming Challenges of Implementing Network Monitoring in OT Environments
Network monitoring plays a crucial role in meeting security regulations, enabling the detection of security and operational anomalies. Implementing security solutions in OT environments is challenging, especially when adding security to existing infrastructures not originally designed with it in mind. Establishing a separate, robust network visibility infrastructure that doesn’t impact production traffic is fundamental for effective OT network monitoring. This infrastructure ensures that all necessary network traffic reaches security sensors and probes efficiently, reducing operational complexity and costs.
Benefits of a separate network visibility infrastructure
Complete Visibility/Elimination of Blind Spots: Cubro TAP devices provide full access to all network traffic, eliminating blind spots without relying on unreliable methods like OT switch mirroring. Network tapping offers comprehensive visibility into OT network traffic, enabling the detection of anomalous behaviour and potential security threats.
Easy Integration with Monitoring Tools: Network Packet Brokers seamlessly integrate with existing monitoring and security tools, such as IDS and SIEM platforms, ensuring optimal performance and protection of monitoring tool investments.
Real-time Monitoring: By capturing network traffic in real-time, network tapping enables proactive monitoring and swift threat detection, allowing security teams to respond before incidents escalate.
Granular Analysis: Network tapping facilitates detailed network traffic analysis at the protocol level, which is essential for understanding security threats and conducting forensic investigations.
