Network and Systems Engineering Cyber Security

It is surprisingly often that the world, usually unconscious of the risks though sometimes conscious of them, falls on new developments such as the Internet of Things (the linking of devices via the ‘cloud’). This already leads to record DDoS (Distributed Denial of Service) attacks, but in the future, may also lead, for example, to mobile network failures or power cuts or a combination of both. Cybersecurity is relevant to all disciplines.

About the research group

The Network and Systems Engineering Cyber Security research group focuses on three key areas:

  • Identity and Access Management
    How we determine who can access a system and when that access is acceptable.
  • System Security, with an emphasis on the Internet of Things
    New applications enable uses to use the data in their devices safely
  • Usable Security
    Finally, Usable Security investigates the intersection between application security and human factors: how can we build secure systems that users want to use rather that looking for ways around them?

All of these are increasingly important, as they are of great societal and economic significance. As cybersecurity is relevant to all disciplines and a must for every professional, whether we are talking about the health industry or in the economic domain where new e-commerce business models arise continuously. That is why the research group works together with all the research platforms, but primarily with Good Governance for a Safe World. This requires multidisciplinary research combined with the expertise from, for example, legal specialists and public administration officials.

Examples of practice-based research

Health care

The research group studies how the use of smartphones connected to smart devices like blood pressure monitors and scales can be optimised for both patients and their doctors. The limiting condition here is that patient privacy is guaranteed and personal and private data only shared with the treating physician.

IoT

The research group studies information ‘leaked’ in the market by IoT devices. Even if information cannot be read directly from a device due to encryption, there is still much information that can be accessed based on the data traffic. For example, if we monitor the rough data traffic to and from door sensors and see that there is indeed a flow of data, we can assume that the sensors are in use.

About the professor

dr. Thomas Quillinan

Thomas Quillinan is a lector of Network and Systems Cyber Security at The Hague University of Applied Sciences and a senior researcher and programme manager for Security at Thales Research and Technology Nederland. In his work at Thales, he is responsible for the coordination and delivery of activities related to safety research at TRT Nederland. He works together closely with the safety research group at Thales, as well as organisations and networks working nationwide on developments in Network & Systems Engineering Cyber Security. Thomas earned his PhD in Security for Distributed Systems and his Master’s in Computer Science from the University College Cork in Ireland. Prior to this, he was a member of the IIDS group at the VU University Amsterdam, where he worked on safety for distributed systems and crisis management. Thomas originally studied Computer Engineering in the University of Limerick in Ireland. His interests include research into the security of information and distributed systems. He holds both the CISSP (Certified Information Systems Security Professional) and CEH (Certified Ethical Hacker) certifications.
