PROBE-BASED RISK ANALYSIS FOR MULTI-FACTOR AUTHENTICATION

摘要

A system for probe-based risk analysis for multi-factor authentication having a multi-dimensional time series data server configured to monitor and record a network's traffic data and to serve the traffic data to other modules and a directed computational graph module configured to probe connection destinations for a response, analyze any received responses, and determine a verification score needed before granting access based at least in part on the analysis of the received responses. A plurality of verification methods build up a user's verification score to required level to gain access.
