Patent ID: 8800037

Claim:
A cyber threat forecast engine system comprising: a memory; a forecast information database (DB) configured to store forecast information including a plurality of cyber threat forecast items with a forecast item hierarchical structure, a forecast schedule and forecast model information related to each of the cyber threat forecast items, hierarchical structure information between the cyber threat forecast items, cyber threat time-series data, and cyber threat sample data; a forecast engine core sub-system configured to forecast degrees of threat for the cyber threat forecast items with the forecast item hierarchical structure using the forecast information stored in the forecast information DB; and a forecast engine control interface configured to receive a control instruction for the forecast engine core sub-system from a user or external system and transfer the control instruction to the forecast engine core sub-system, wherein the cyber threat forecast items with the forecast item hierarchical structure comprise cyber threat forecast items belonging to a lower level of the forecast item hierarchical structure and cyber threat forecast items belonging to an upper level of the forecast item hierarchical structure, and wherein the forecast engine core sub-system is configured to calculate a forecast value of a degree of threat with respect to each of the cyber threat forecast items belonging to the lower level of the forecast item hierarchical structure, and further calculate a forecast value of a degree of threat with respect to each of the cyber threat forecast items belonging to the upper level of the forecast item hierarchical structure by giving weights to the forecast value of each of the cyber threat forecast items belonging to the lower level of the forecast item hierarchical structure and adding up the weighted results.
