Tracer Records are intrusion detection from an unfamiliar angle. Typical countermeasures try to keep intruders out or look for their signatures, anomalies, and footprints. Tracer Records hide inside of your data; they are simple and unexpected.
When a data theft occurs, organizations are often unaware, frequently for a while, sometimes forever. Tracer records can remedy that knowledge gap. They improve your intelligence about data breaches, but more than that, Tracers let you know who is walking off with your data and provide additional ammo for prosecution.
