Integration methods for host intrusion detection into embedded mixed-criticality systems

Host: SYSGOResearch and Technology.

    • Prof. Gerhard Fohler,


  1. Develop security monitoring solutions capable of detecting security attacks in industrial embedded mixed-criticality systems (MCS).
  2. Integrate the security solutions into the PikeOS hypervisor.


  • We defined a safety-aware architecture to integrate host intrusion detection system (HIDS) into an industrial embedded MCS. The approach is compatible with system certifiability towards industrial deployment.
  • We defined a set of metrics to evaluate the HIDS in regards to security, performance, and system schedulability impacts
  • We developed two monitoring approaches:
    • Transparent Control-Flow monitoring framework, using hardware assistance
    • Non-intrusive machine-learning based HIDS for embedded MCS
  • We implemented the proposed security monitoring services as extensions of SYSGO’s PikeOS real-time hypervisor and evaluated the overhead of the implemented solutions.

Collaboration with Prof. Gerhard Fohler:
