Rule 7 · Action: Audit only + mask sensitive text (hover to reveal) · Trigger: URL visited
Data masking — SSN, hover to reveal
Set the rule's URL condition to cepdemo.mobi-sec.de (replaces
dlptest.com from the guide). The mask method is Hover to reveal for the
Social security number expression. SSNs follow the dlptest.com generation rules —
valid area-group-serial structure so detectors fire, but entirely fabricated.

- On load, every SSN above is visually masked.
- Hovering an individual masked value reveals it; moving away re-masks it.
- Surrounding text (names, departments) stays readable — only the matching pattern is masked.
- An audit event is written; the page itself is never blocked.
