Cybersecurity for IoT solutions

The ongoing digital transformation of all areas of life and work places increased demands on the security of systems and requires a deeper understanding of the interaction between networked devices, systems and users. With the increasing digitalisation of society, the threat potential for cyberattacks is also increasing significantly. In addition to already known attack patterns, the focus is increasingly shifting to scenarios that affect critical infrastructures (e.g. energy supply, drinking water supply, urban drainage, wastewater treatment). In the smart city environment, more and more networked systems are being established, usually with IoT-based infrastructures, which form the basis for critical decision-making processes, among other things. Monitoring these IoT solutions is necessary in order to recognise failures and anomalies at an early stage and ensure a secure data basis.

Fraunhofer IOSB-INA has developed the Cyber Detect analysis software, which is used to monitor the life cycle of IoT applications. It analyses the communication between controllers and devices in real time. The analysis software continuously checks the communication data for anomalies. If an anomaly is detected, an alarm is triggered. The alarm can be used to initiate manual and automatic countermeasures, such as putting the system into a safe state. Cyber Detect is equipped with standardised interfaces such as OPC UA to ensure simple integration and configuration.  

Functions:

• Classification of cyber attacks 
• Anomaly detection 
• Real-time analysis 
• Deep packet inspection
• Standardised interface through OPC UA
