Despite the availability of security tools, devices are still vulnerable to compromise via the risky security behaviour of end-users. Risky behaviour is not necessarily obvious to all end-users, and can be difficult to recognise. Lynsay is interested in the human aspects of cyber security, investigating how to effectively communicate security information to average end-users.

Lynsay’s PhD research explored the fields of affective computing and usable security. The project investigated the use of a browser extension to monitor and automatically detect risky security behaviour. On detection of such behaviour, affective feedback was delivered to the end-user. The work analysed the impact of the feedback in relation to end-user security awareness.
