SECURITY EVENT MONITORING DEVICE, METHOD, AND PROGRAM

摘要

The security event monitoring device includes: a storage module which stores in advance a correlation rule; a log collection unit which receives each log from each monitoring target device; a correlation analysis unit which generates scenario candidates by associating each of the logs; a scenario candidate evaluation unit which calculates the importance degrees of each scenario candidate; and a result display unit which displays/outputs the scenario candidate of a high importance degree. The scenario candidate evaluation unit includes: a user association degree evaluation function which calculates user association degrees; an operation association degree evaluation function which calculates the operation association degrees; and a scenario candidate importance reevaluation function which recalculates the importance degrees of each of the scenario candidates by each user according to the user association degrees and the operation association degrees.
