In spite of the existence of security challenges to develop informational and servicing structures, web services are important for organizations. There are so many things done to compensate for their security shortcomings, including replacing security standards in their structure to provide defensive tools such as web services firewall. Due to the is attempting inefficiency of the current Intrusion Detection Systems (IDS) in recognizing web services attacks, current research to enhance these systems' level of security for the web services' activities. The efficiency of the prevalent Intrusion Detection System can be compared and assessed using different parameters. But these methods are inefficient in the area of web systems. In this article, according to the implemented chores in the area of anomaly detection in the web services, we are going to evaluate the efficiency of Hidden Markov Models as a being-used method in the Web Services Anomaly Detection (WSAD) groundwork. The assessments' methods and results can be used as an efficient and important step in guaranteeing web services.
