Code Integrity Attestation for PLCs using Black Box Neural Network Predictions

no code implementations15 Jun 2021 Yuqi Chen, Christopher M. Poskitt, Jun Sun

Cyber-physical systems (CPSs) are widespread in critical domains, and significant damage can be caused if an attacker is able to modify the code of their programmable logic controllers (PLCs).

Privacy Preserving

Adversarial Attacks and Mitigation for Anomaly Detectors of Cyber-Physical Systems

no code implementations22 May 2021 Yifan Jia, Jingyi Wang, Christopher M. Poskitt, Sudipta Chattopadhyay, Jun Sun, Yuqi Chen

The threats faced by cyber-physical systems (CPSs) in critical infrastructure have motivated research into a multitude of attack detection mechanisms, including anomaly detectors based on neural network models.

Learning from Mutants: Using Code Mutation to Learn and Monitor Invariants of a Cyber-Physical System

no code implementations3 Jan 2018 Yuqi Chen, Christopher M. Poskitt, Jun Sun

Cyber-physical systems (CPS) consist of sensors, actuators, and controllers all communicating over a network; if any subset becomes compromised, an attacker could cause significant damage.

Anomaly Detection for a Water Treatment System Using Unsupervised Machine Learning

no code implementations15 Sep 2017 Jun Inoue, Yoriyuki Yamagata, Yuqi Chen, Christopher M. Poskitt, Jun Sun

In this paper, we propose and evaluate the application of unsupervised machine learning to anomaly detection for a Cyber-Physical System (CPS).
