Abstract:
Disclosed in the present invention are a method and system for preventing a DDOS attack of a "zombie" terminal. The method comprises: an HSS server receiving and recording a network bearing request which is initiated by a terminal, acquiring a corresponding HSS error code, and state information of the terminal, and determining whether the terminal meets a preset number card determination condition; if so, defining the terminal as a "zombie" terminal; after the terminal is determined to be a "zombie" terminal, the HSS server acquiring an IMEI code of the terminal, and sending the IMEI code to a connection management platform; the connection management platform issuing a communication function disabling instruction to an Internet of Things card of the terminal; and the Internet of Things card executing the received communication function disabling instruction, disabling a communication function of the terminal, and returning a disabling result, such that the connection management platform executes dismantling or shutdown processing on the Internet of Things card. By means of the method, a "zombie" terminal is fundamentally and automatically found, and an operation of disabling a communication function module of the "zombie" terminal is performed, thereby thoroughly resolving a DDOS attack initiated by the "zombie" terminal, and greatly increasing the communication success rate of an area.
