1. An anomaly malicious code detection system using a process behavior prediction technique, comprising: a DB filtering module performing primary malicious code filtering with respect to execution codes executed in a system; a system resource monitor module monitoring a system resource to collect each event information generated by the execution codes executed in the system; a reprocessing module reprocessing each event information collected in the system resource monitor module to reconstruct it into one integrated log representing a related behavior feature value of the execution codes; a behavior prediction information processing module inputting the integrated log reconstructed in the reprocessing module into a learning algorithm to extract an anomaly malicious behavior feature value (a prediction pattern); and an anomaly malicious behavior detection module comparing the anomaly malicious behavior feature value extracted from the behavior prediction information pressing module with the behavior feature value data constructed in the reprocessing module to detect a malicious behavior.
