Research On Fixing Technology Of Android System Vulnerabilities Based On Container

The rapid development of Android poses a huge threat to system security,and the emergence of system vulnerabilities seriously affects the security of Android system.Under such an environment,the fixing of Android system vulnerabilities should be effective and reliable.However,most of the existing vulnerability fixing technologies rely on the way of modifying source code,and the constant updating of Android system version brings many troubles to vulnerability fixing.This paper focuses on the problems in the Android vulnerability fixing and excavates the characteristics of the system vulnerabilities.Based on the above research,this paper proposes an effective solution.This scheme uses the concept of container to protect the system,and solves the complex problems of source code dependence and version fragmentation.The main work of this paper is as follows:1)Take a systematically study on the vulnerabilities of Android system,which includes collecting the vulnerability relative information,giving a knowledge to current vulnerability security situation.This paper elaborates the situation of vulnerability classification,vulnerability life cycle and Android security mechanism in detail.2)Give an intensive research on the vectorization of vulnerability features,which includes establishing the quantification process of vulnerability features and constructing the feature vector database of system vulnerabilities.This paper even creates the mapping rules between features to provide assistance for vulnerability fixing.3)Build vulnerability protection scheme based on vulnerability feature information,which includes designing the customization process of fixing components,constructing the fixing component database and finally implementing the compilation of fixing code.4)Based on the above protection scheme,the fixing container is designed and implemented.The container implements the combination with the fixing component.These two parts cooperate to complete the vulnerability fixing in the application layer.This paper verifies the secure performance and practical performance of the fixing container through experimental analysis.The experimental results show that the proposed vulnerability protection scheme achieves the fixing work of Android system vulnerabilities and improves the security of Android system.
