Design And Implementation Of Security Supervising System Based On Android

With the rapid development of mobile Internet technology, while brings much convenience for people’s life and work,also brings international potential security threads. The great openness of Android system provides a platform to spread malicious applications. These malicious applications steal user’s personal data,connect to the Internet automatically and send SMS in the background, causes huge economic losses to users. After a fully research of the development of Android and Android application security, on a basic of comparing the characteristics of the current domestic and international mainstream security supervising system,we design and present the implementation of the security monitoring system.In this paper, the research of the existing Android applications detection and security supervising,summarizes the Android applications that access the users private data、SMS、contacts、the information of SIM card and the location information lead to the information leakage. Design the Security Supervising System based on Android platform to monitor and manage the application has been installed. The four modules are network firewall modules, information firewall modules, mobile anti-lost modules, traffic monitor modules. The network firewall module uses tcpdump to realize the data collection of the application program which is visiting the network, the module can be used to monitor the network behavior of the applications. The information firewall module uses the broadcast to monitor the phone in the background, and realizes the interception of phone and SMS. The mobile anti-lost modules is used to protect the privacy of the moblie phone. The traffic monitoring module is based on the iptables rule chain to achieve the flow of statistics and control.After testing of the system proves that the founctions of the systemic Android packet capture,telephone intercept,SMS intercept mobile anti-lost and traffic monitor are able to run,the overall function of the system basically satisfy the expectation of the design.
