Towards an anomaly detection technique for web services based on kernel methods
Reyhaneh Ghassem Esfahani, Mohammad Abdollahi Azgomi · 2009
A large number of enterprises are turning to service-oriented architecture (SOA) for designing, using and managing their information technology (IT) systems. SOAP-based web services are the most commonly found services in today's SOA implementations. This paper reviews different possible classes of vulnerabilities in web services and investigates the advantages and shortcomings of available solutions. We aim to find an anomaly detection method, which is sensitive to XML semi-structured data and is appropriate for web services. For this purpose, a new approach for anomaly detection in web services is proposed by employing kernel methods. The proposed technique is capable of detecting new unknown attacks in XML contents of the SOAP messages.
