Design And Research Of Early Warning System Detection Based On Python

Modern AWACS is a large platform which has remote detection,information distribution,command coordination,joint operations,it's not just a pure air radar.It carries a large number of electronic equipments,including radar,data link system,signal transceiver system,and so on,so early warning system of each electronic equipment system's own security issues are particularly important.This paper makes a detailed analysis of the early warning system and security strategy,according to the domestic and foreign mainstream system safety testing means that all potential security problems are: each subsystem of AWACS is mainly dominated by Linux,the lack of mainstream anti-virus software;common security means to stop the external invasion,internal malicious tampering the contents of the file system operation can not be detected;the existing detection means the lack of means of real-time monitoring of early warning system,and can only be detected in the field,the lack of remote detection function.This paper focuses on solving system security problems,main work are as follows:Firstly,the development of embedded intermediate detection equipment is studied.The advantage of embedded devices,embedded devices are installed on the site for remote operation.Raspberry Pi based on ARM framework in the middle test equipment,Raspberry Pi in full compliance with the performance testing work,combined with the characteristic of RPi,Python is selected as the main development language,C/C++ and shell script as a secondary development.Secondly,the research presents the software application in the form of Web interface.According to the characteristic of Linux operating system,selected the Web interface to implement software application function.Django as a lightweight web of Python is,powerful and easy to develop.Django Web will built and deploy to the raspberry pie,according to the advantage of the Python language,the application and the underlying hardware compatibility developmentare very high.Finally,the research of software detection function.According to the need of early warning detection,through the SSH protocol to realize the remote connection function;through the realization of MD5 algorithm,view the file information,to determine whether a file has been tampered with;the design of port scanner,view port state;according to the detection of early warning aircraft all components of the system CPU,memory,process and log files and other informations,to identify the warning machine work status and safety.On this basis,the software detection function is integrated into Django Web to realize remote detection function,which proves the feasibility of Web interface form to realize software application program.
