Abstract
This use case addresses a common source of false positives in identity security. KRYOS-XS evaluates whether unusual activity is malicious, legitimate or unresolved by combining technical evidence with institutional context.
Decision problem
Rules that treat every new location or device as hostile can disrupt field operations and train users to ignore warnings. Conversely, contextual explanations can be used to excuse genuine compromise. The decision must therefore account for both behavior and consequence without allowing either to dominate the assessment.
Evidence and Hypercube reasoning
Console retrieves approved login, device, authentication, role, file and alert evidence. Where the organization supplies valid travel or operational context, Hypercube treats it as one source rather than a conclusive explanation. Competing hypotheses are scored against the whole evidence set, and missing facts are translated into specific verification requests.
Governed workflow
Console detects the identity-risk case and frames the exact decision. Hypercube tests legitimacy, credential sharing and compromise. The output may recommend no action, step-up authentication, restricted access, session revocation or human investigation. The final disposition and subsequent outcome are recorded.
Evaluation design
Measures should include confirmed compromises, false account suspensions, time to resolution, cases resolved through targeted verification, repeated user friction and the rate at which the initial conclusion changed after new evidence.
Boundary condition
Travel context should reduce neither evidentiary standards nor the need for protective action when the technical record supports compromise.
Reading time 2 minutes. Every decision described here is recorded in the KRYOS Decision Ledger with its evidence, authority and verified outcome.
