Network Monitoring Cyber Security

OT Monitoring & Intrusion Detection

Step 2: Detect cyber attacks and changes in your OT with Rhebo Industrial Protector

Cybersecurity does not end at the network perimeters.

Modern automated industrial networks must be secured like a modern nation state. The Rhebo OT monitoring with next generation OT threat and intrusion detection advances the existing perimeter firewall security by integrating a holistic anomaly and intrusion detection within the Operational Technology. Even successful attacks via security gaps in the firewall, brute force, zero-day exploits, internal perpetrators, backdoors or stolen credentials are detected at an early stage.

What You Get…

  • Optimized OT visibility

    … through real-time visualization of communication behavior of all OT and IIoT assets (protocols, connections, frequencies) with the OT

  • Comprehensive OT security

    … through real-time reporting and localization of cyber attacks, manipulation attempts and technical error states across the entire infrastructure

  • Extended intrusion detection

    … through early identification of attacks via backdoors, previously unknown vulnerabilities and internal adversaries that firewalls fail to detect (defense-in-depth)

  • Hardened legal compliance

    … through continuous monitoring of OT communication and integrated IDS according to international standards and national IT security laws

How the Rhebo OT Monitoring with Anomaly Detection Works

Real-time Threat & Intrusion Detection

Rhebo OT monitoring with anomaly detection monitors all communication within, to and from the operational technology 24/7. The monitoring is integrated non-intrusively and passively at key points of the OT. Any communication that indicates cyberattacks, tampering, espionage or technical error conditions is reported in real time. This allows early detection of progressive attack patterns as outlined by the MITRE ATT&CK framework.

Companies can then respond quickly to risks and ensure the security and availability of their industrial processes.

Cross-location Monitoring for Internal OT Security

Rhebo OT monitoring with anomaly detection can be easily installed across multiple sites and operated centrally. The sensors are installed as lightweight hardware or an integrated software solution on existing security gateways, network components and IIoT edge devices. For distributed IIoT edge devices, an active version with security automation is also available to ensure real-time fleet security.

Companies gain visibility and clarity across their entire networked, industrial infrastructure at all times - regardless of how far a facility is located from the central control room.

Detailed Documentation & Threat Intelligence

Rhebo OT monitoring with anomaly detection continuously visualizes and documents all active devices and systems in industrial infrastructures. Important properties such as firmware status, protocols, behavior patterns and existing CVE vulnerabilities are documented on a daily basis. Any identified anomaly is recorded with all details as PCAP. The threat intelligence information can be forwarded to SIEM systems or other security components.

Companies gain a comprehensive picture of their risk exposure and can react to threats quickly and in a targeted manner.
