Evolutionary Learning Program's Behavior in Neural Networks for Anomaly Detection

Learning program’s behavior using machine learning techniques based on system call audit data is effective to detect intrusions. Among several machine learning techniques, the neural networks are known for its good performance in learning system call sequences. However, it suffers from very long training time because there are no formal solutions for determining the suitable structure of networks. In this paper, a novel intrusion detection technique based on evolutionary neural networks is proposed. Evolutionary neural networks have the advantage that it takes shorter time to obtain superior neural network than the conventional approaches because they learn the structure and weights of neural network simultaneously. Experimental results against 1999 DARPA IDEVAL data confirm that evolutionary neural networks are promising for intrusion detection.
