Embodiment

[0038] Such as figure 1 As shown, the DDoS defense system includes a control module 10, a system monitoring module 20, and a system processing module 30, wherein the control module 10 is responsible for starting, initializing, suspending and closing the defense system, and the initialization setting of the defense system includes abnormal times SYN Packet rate threshold, ACK_SYN packet rate threshold, UDP packet rate threshold, abnormal times threshold, the initialization setting of the defense system may also include monitoring interval time and monitoring duration.

[0039] System monitoring module 20 is used for monitoring system network port, monitors the sending and receiving of data packet, if current process sends to the SYN bag of same IP address same port, ACK_SYN bag or UDP packet rate exceeds rate threshold value, then starts system processing module 30 , and transmit the abnormal process data to the system processing module 30.

[0040] The system processing modul...

Abstract

The invention provides an android system-based distributed denial of service attack (DDoS) defense system and method. Programs of the defense system are installed in an android system of a mobile platform, whether the rate of a synchronize (SYN) request, ACK-SYN response or user datagram protocol (UDP) package which is sent to the same port of the same internet protocol (IP) address in a current process exceeds a set threshold value or not is subjected to timing detection through a network port of a monitoring system, an abnormal process of sending data packages is tracked, recorded and stopped, and defense against DDoS on the mobile platform can be achieved. According to the android system-based DDoS defense system and method, the DDoS defense system is easy to install, network flow and system costs are extremely low, normal usage of the mobile platform is not affected, and technical problems that existing DDoS defense methods are complicated in deployment and implementation, high in resource costs and not suitable for the mobile platform can be solved.

Description

technical field [0001] The invention relates to the technical field of mobile platform security, in particular to a DDoS defense system and method based on an Android system. Background technique [0002] Distributed denial of service attack (distributed denial of service attack, DDoS) is to send a large number of normal requests to the target system at the same time by controlling multiple machines on the Internet, so that the victim server suffers from an unbearable mass of requests, causing the server to be unable to process real requests, thereby To achieve the purpose of denial of service attack. DDoS attacks on the Internet have been emerging in an endless stream, which has plagued network service providers. With the rapid development of mobile platforms such as smart phones, the continuous integration of mobile Internet and traditional networks, and the increasing number of mobile platform users, mobile platforms have gradually entered the field of vision of network ...
