Attack graphs

How people perceive cyber attacks

Empirical studies of attack graphs, attack trees and MITRE ATT&CK in helping decision-makers understand attacks, published in IEEE Transactions on Information Forensics and Security, Computers & Security and Computer Science Review.

Digital forensics

Evidence from everyday devices

Dashcam forensics, iPhone geo-tags, BitTorrent registry artefacts and cloud investigations, plus guidelines now used in practice.

Threats and incidents

Understanding real-world attacks

Cyber attacks during the pandemic, attacks on universities and schools, and the Horizon scandal analysed as a socio-technical failure.
