The system - a prototype is likely to be ready for intensive testing this summer - could provide a high-grade layer of protection for military installations and government agencies as well as banking or other commercial networks that require especially tight monitoring. The "user-level anomaly detection" software draws up regularly updated profiles by closely tracking over time how each person performs an array of routine tasks, such as opening files, sending e-mail or searching archives.

    Designed to tell if someone has strayed into an unauthorized zone or is masquerading as an employee using a stolen password, the program keeps watch for even subtle deviations in behavior. Alerted to anomalies, network administrators then begin monitoring more aggressively to assess whether pilferage is in progress.
