Human factors

A number of SCCS Core and Associate members have expertise in human factors in cyber security and cybercrime, and their work has led to many successful research publications and research grants.

Recent projects

Recent projects have included cognitive modelling of human behaviour in user authentication systems, and human-assisted data loss/leakage prevention, while a new project – ACCEPT – aims to identify better ways to collect, understand and influence the behaviour of criminals, victims and organisations to reduce human-related risks in the cyber-physical world. 

Case study: COMMANDO-HUMANS project

The security of computer systems often depends on the way humans interact with them, but testing systems with humans in the loop brings a number of problems. In addition to time and cost implications, issues include limited or biased samples, lack of ecological validity due to people behaving differently in tests, and the impossibility of running some studies due to ethical, privacy or legal concerns.

Creating software capable of simulating and modelling how humans interact with security systems would therefore help security designers and implementers to save time and money – and offer more reproducible and possibly more accurate results than human-based testing.

The ‘COMMANDO-HUMANS’ project, which is jointly funded by EPSRC and Singapore’s National Research Foundation (NRF) as a result of the 2015 Joint Singapore-UK Research in Cyber Security call, aims to produce direct evidence that insecurity caused by human behaviours can be detected automatically by applying human cognitive models. Launched in April 2016, the project involves researchers from four different countries (UK, Singapore, Australia and Croatia).

The two year project aims to develop the first software framework that can automatically detect both security and usability problems without the need to involve real human users. The framework will be developed around human user authentication systems as a focused use case. When developed, this framework could be used in sectors such as banking to test both usability and security of user interfaces, and to compare the performance of different solutions.

The research focuses mainly on ‘micro’ human behaviours at the user interface level, but will also look at ‘macro’ behaviours related to higher-level cognitive processes such as human perception, decision making, human errors and adaptive learning. This will lay the foundation for follow-up research and help increase our knowledge of other human-related security issues such as social engineering and insider threats.
