Most active research in Host and Network Intrusion Detection Systems are only able to detect attacks of the computer systems and attacks at the network layer, which are not sufficient to counteract SOAP/REST or XML/JSON-related attacks. In dealing with the problem of anomaly detection in web service message datasets, this paper proposes an anomaly detection system called the Online Adaptive Deep-Packet Inspector (O-ADPI) for web service message attacks classification. The proposed approach

We utilize a supervised intrusion detection algorithm based on mahalanobis distance map classifier. As web service attacks can be classified into anomaly and normal, the task of anomaly detection can be modeled as a classification problem. The O-ADPI model was assessed for F-value, true positive rate (TPR), and false positive rate (FPR) in order to evaluate the detectionx performance of O-ADPI against different type of feature selections engines with corresponding PCs for each service messagespecific. The experiments were performed using the REST-IDS Dataset 2015 and the results demonstrated that the proposed O-ADPI model achieved the best results in each message-specific service.
