The present application relates to a security testing method, apparatus, computer equipment and storage medium. The method relates to the technical field of information security, and the method includes: generating a simulated network message according to input parameters of an application to be tested, and transmitting the simulated network message to a virtual server program in a user terminal; In the process of transmission to the virtual server program, the simulated network message is intercepted; the simulated network message is processed, and a security test is performed based on the processed simulated network message. That is, in the embodiment of the present application, a simulated network environment can be established locally on the user terminal, which can avoid the problem that the application program directly interacts with the server, so that the man-in-the-middle test module cannot obtain the input parameters and thus cannot perform the security test. The network message is processed, and the security test of the application to be tested is realized by processing the simulated network message, so as to improve the security test efficiency.
