Research On Dynamic Behavior Monitoring Of Android Smart Phone In Closed Environment

Smart phone is a great invention in the 21 st century,a cross-epoch development of human society,and the most widespread and revolutionary communication tool.However,with the popularity of smart phones,the use of mobile phone infringement,exposure to privacy and leakage of secrets are increasingly prominent,especially in military areas of the environment such as secret places,smart phone communication information security is more severe.The military information is related to the national political,milita ry and security secrets,which is related to the stability of the country and the development of the society.It has special requirements for the security and security of smart phone communication information.At present,with the development of communication technology,some criminals with ulterior motives make use of the vulnerabilities of smart phone system to spread virus or Trojan program maliciously for personal benefit.Even the application program with some unsafe factors has been gradually infiltrated into some secret sites of our country,especially some military secret sites in our country have achieved the purpose of stealing military secrets.In order to prevent the leakage of secrets,some of the army's core secret sites simply prohibit the entry of Smart phones to ensure the security of communication information.In this way,there are some drawbacks,although the security of information data is guaranteed,but at the same time,it is also self-contained and unable to receive the update of external information,which makes the army construction lag behind the modern development.How to obtain and update the knowledge information data quickly while ensuring the security of the data is a challenge for the smart phone in the closed environment,such as the military secret places,so it is difficult to screen the large amount of information in the smart phone network.Rapid diffusion of sensitive information is an effective method for dynamic behavior monitoring.At present,there are a lot of researches on the security design of smart phone,but the research and application of dynamic behavior monitoring of smart phone is still very weak.In this paper,we take the closed environment such as military area,secret place and so on as the angle of view,combined with the current situation of smart phone application.The research on smart phone dynamic monitoring widens the research field of smart phone information security management.In this paper,the dynamic behavior monitoring of smart phone in closed environment is the research subject,and the dynamic behavior monitoring of smart phone in closed environment is the visual angle.Based on the existing research results,the characteristics of smart phone application program are summarized.Smart phone be havior monitoring technology,smart phone dynamic behavior classification,etc The theoretical basis of this study;Then,combined with the smart phone architecture,the general framework of smart phone dynamic behavior monitoring system in closed environment is constructed,and the design of address book abnormal information management,short message service abnormal information management design,call and recording abnormal management design are completed.Statistical query management design;Finally,a s mart phone dynamic behavior monitoring system under closed environment is designed to realize the monitoring and protection of smart phone privacy data.The main research results are as follows:(1)in this paper,the dynamic behavior monitoring model of smart phone in closed environment is designed,and the dynamic behavior monitoring scheme of smart phone in closed environment,such as military area,secret place,is put forward.Design and implement the smart phone dynamic behavior monitoring system in closed environment.(2)this paper completes the monitoring of the dynamic behavior of the smart phone in the closed environment,monitors the controlled end through the sending of instructions,and realizes the purpose of remote monitoring.The main functions are the management of the basic abnormal information in the address book.Short message service abnormal information management,file access exception information management,call and recording abnormal management and so on.
