Design of an Automatic Detection System for Abnormal Communication Data Packets of Electronic Equipment

In order to prevent abnormal communication packets from spreading in the Internet, an automatic abnormal communication packet detection system is designed to detect abnormal communication packets accurately. The Internet uses the Web server as the carrier to transmit communication packets, and the data packet capture module adopts WinPcap technology to obtain effective data packets. In the protocol parsing module, the decoding work of TCP/IP protocol, CMP protocol and UDP protocol is completed, and the decoded data is input into the abnormal communication packets detection model of electronic equipment based on SVM. The SVM model seeks the optimal hyperplane to divide the abnormal communication packets of electronic equipment into abnormal and normal packets, and completes the automatic detection of abnormal communication packets of electronic equipment according to the results. Experimental results show that the false positive rate of abnormal communication packets is less than 3%. Compared with the same type of system, the system has the advantages of high receiving capacity and high efficiency.
