Protection of network availability and cybersecurity in the automotive industry (case study)

Case Study Automotive Rhebo
  • Rhebo publishes case study showcasing its industrial anomaly detection for IIoT environments
  • The 24/7 monitoring found several anomalies which indicated operational errors as well as cybersecurity incidents

Leipzig, Germany 11/04/2018 - Rhebo integrated a pilot installation for seamlessly monitoring the Industrial Control System at one of the German plants of an automotive manufacturer. With the Rhebo solution the automotive manufacturer addressed the classic aspect of cybersecurity in ICS as well as the challenges due to the technical developments of Industry 4.0 and IIoT.

The accelerated networking of production plants also increases the complexity of ICS leading to a growing susceptibility for disruptions. Thus, the vision of IIoT can only be successfully implemented, if ICS are perceived and treated as the vital nervous system of modern plants. This development is recognized by recent standards and regulations focussing on the protection of ICS as part of ensuring process continuity.

Complexity of ICS is growing

Within a very short time, Rhebo installed its non-intrusive industrial anomaly detection Rhebo Industrial Protector in one production cell of an automotive manufacturer to address those challenges. Already the first analysis during the Rhebo Industry 4.0 Stability and Security Audit (RISSA) revealed a surprisingly strong heterogeneity and complexity of the system architecture. In the monitored production cell alone more than 300 networked components by different vendors and with varying configuration were found.

Continuity is not only about cybersecurity

During operation Rhebo Industrial Protector identified a variety of continuity threats which were classified in two categories: cybersecurity threats as well as threats caused by technical inefficiencies (network quality). Both threaten the overall equipment efficiency (OEE). One detected anomaly in the network behavior indicated a potential man-in-the-middle attack, another revealed unknown devices and users. Furthermore, several network problems were identified which were caused by misconfigurations, network degradation as well as equipment errors.

With Rhebo Industrial Protector the automotive manufacturer gained full transparency of its monitored production network. Misconfigurations and potential security threats got identified and analyzed for further mitigation. With Rhebo Industrial Protector the automotive manufacturer took the first step to an improved continuity and increased process stability.
