Presentation / Conference Contribution
Thomson, A., Graham, M., & Kennedy, J. (2013, July). Pianola - visualization of multivariate time-series security event data. Presented at 17th International Conference on Information Visualisation

Monitoring log files for network intrusions is unwieldy. To build a mental model of the log, an analyst is required to recognise continuous timelines and attack patterns from a dataset that is essentially limited to an ordered list of events. Informa...
