Research On Vulnerability Analysis,Malware Analysis And Safety Assessment Of Intelligent Terminal

With the rapid development of mobile Internet, intelligent terminal spreads quickly and has become the most popular mobile devices currently, so that more and more industries are involved. However, from the day when the intelligent terminal came into being the security problem has been as the shadow follows the form, and the trend is still worsening. There are two main safety problems:security vulnerabilities and malicious software, which not only seriously affect the normal use of the intelligent terminal user, it will cause users’loss of property and information disclosure and other harsh consequences.In order to solve the two safety problems, this paper takes Android system as the main research platform, combining with the system framework and the security mechanism of Android, makes deep research in vulnerability and malware of intelligent terminal, and put forward the implementation framework of assessment for the safety of intelligent terminal. The concrete research contents and results include the following four points:1. The paper has learnt the relevant study of vulnerability analysis, malware analysis and safety assessment of intelligent terminal, analyzes the system architecture and the security model of Android, and provides the theory support and basis for the following work.2. The paper builds an intelligent terminal vulnerability database using crawler technology, collecting and integrating the vulnerability data of the intelligent terminal, and realizes the data management and application. On the basis of data analysis, combined with the unique characteristics of intelligent terminal, the paper proposes a classification model based on star network to analyze vulnerability comprehensively.3. The paper analyzes the characteristics of the Android application and the privilege security mechanism, combined with the simple Bias classification algorithm, designs and realizes the analysis system of malware based on the characteristics of privilege to separate the malware by the characteristics in the combination of privilege, and lastly the effectiveness of the system was verified by real data.4. The paper analyzes security problems from the aspects of intelligent terminal’s operating system, applications and data and put forward the safety assessment framework of Android intelligent terminal. The framework includes safety assessment of the three parts above, and combined with the foregoing work, the framework can make a comprehensive assessment of the intelligent terminal’s safety from vulnerability scan, vulnerability mining and many other aspects.In this paper, the research work and achievements provide the idea and solution of the security problems of the intelligent terminal, and have important value of application.
