About This MicroSim

This MicroSim shows how graph-based audit-trail analysis detects inappropriate access to patient records. Users (squares, colored by risk) access patient records (circles) grouped into two wards. Access within a user's own ward is authorized (green edges), while access to patients in the other ward is unusual (red edges) — and a user who reaches across wards to many patients, like RN-Snoop here, shows a snooping pattern that flags a likely privacy violation.

How to Use

Toggle the highlight to emphasize cross-ward access, and click any user to isolate just their access edges and read their access count and cross-ward total in the status line. Spot the user whose red cross-ward edges fan out across the other ward — the kind of anomalous pattern a graph query over the audit log surfaces automatically, where a row-by-row log review would miss it.
