In a log analysis cooperation system including a logger that collects a log of a communication device and stores the log in a storage device, a SIEM apparatus that detects an attack, and a log analysis apparatus that analyzes the log collected by the logger, a log analysis cooperation apparatus stores an attack scenario in a storage device, receives from the SIEM apparatus warning information including information on the detected attack, computes a predicted occurrence time of an attack predicted to occur subsequent to the detected attack based on the warning information and the attack scenario, and transmits to the log analysis apparatus a scheduled search to search the log at predicted occurrence time computed. The log analysis apparatus transmits a scheduled search to the logger to search the log at the predicted occurrence time. |
