Disclosed is an operation method for a dynamic analyzer for analyzing an execution state of a web application. The present invention comprises the steps of: analyzing an execution state of the web application on the basis of a final attack string including a parameter which indicates a particular operation to be executed through the web application; and performing an analysis of the execution state of the web application, wherein the final attack string is generated so as to avoid filtering logic which is designed to filter a raw attack string including a predefined parameter. Therefore, the present invention can detect a security vulnerability, which cannot be detected by the existing dynamic analyzer, through easy generation of a final attack string capable of bypassing filtering.
