Security and Privacy in Machine Learning

Below is a list of topics related to security and privacy aspects of Machine Learning / Data Mining / Artificial Intelligence. If you are interested, please contact Rudolf Mayer

Adversarial Machine Learning:

A good overview talk (in German) into Adversarial Machine Learning is given by Konrad Rieck: “Sicherheitslücken in der künstlichen Intelligenz”: https://www.youtube.com/watch?v=j6nRPg2Y62w  

Privacy-preserving Machine Learning / Data Mining

Privacy-preserving analysis of data is becoming more relevant with the increasing amount of personal data being gathered. Several different approaches aiming at this problem exist, e.g.:

Watermarking / fingerprinting of datasets

  • Goal: evaluation of schemes for their robustness of attacks, vs. their data utility, e.g. measured by effectiveness in machine learning tasks

Digital Sustainability

  • Understanding runtime system behaviour: How can the runtime behaviour of a complex systems be described, modelled and monitored/checked?: Alexander Schatten
    • Literature research and interviews on status quo
    • Implementation of a model e.g.
      • Demonstrate a complex yet resilient component based infrastructure by implementing a (Netflix) Chaos Monkey demonstration setup with Docker/Kubernetes components.
      • Runtime analysis of selected open source system(s): use debug interface of (Java) virtual machine to analyse runtime behaviour, draw a “code-landscape” and identify processes.
    • These topics can also be split into several thesis
  • Understanding and Handling Complexity: Complexity and software systems: Alexander Schatten
    • Find indicators to quantify complexity in software systems and organisations
    • Find and describe systemic patterns and complexity drivers that can help to understand problems in large software systems
    • Analyse typical software and architecture patterns with focus on complexity
    • Analyse the complexity of selected Open Source projects following established complexity- and entropy-indicators. This might include static code analysis and analysis of code changes (source code repository).
  • Understanding and Handling Complexity: Mapping program language related complexity: Alexander Schatten
    • Find useful dimensions of comparison
    • intrinsic complicatedness
    • extrinsic complexity
  • Management and Organisational Dynamic: Map existing IT management frameworks and patterns like ITIL, COBIT, SAFE, ISO9001: Alexander Schatten
    • find useful dimensions for comparison
    • outline overlaps and interfaces
    • describe conflicts and usage scenarios
  • Management and Organisational Dynamic: Analyse organisational hierarchies, setup and processes (cooperation of business partners required): Alexander Schatten
    • Interface between business and IT to derive factors that lead to success or failure
    • Implement a dynamic simulation of an organisation and deduce efficiency “bottle-necks” using e.g. queuing theory

Security for Cyber Physical Production Systems

  • Network Security in CPPS. Which tools (like metasploit) are readily available for pentesting CPPS (instead of business systems)? Edgar Weippl
  • Forensics Analysis in CPPS. Which tools exist that can be used to analyse CPPS? Are there guidelines on how to proceed? Edgar Weippl
  • Secure Software Engineering Processes in CPPS. Edgar Weippl
