Analysis and Research of System Security Based on Android

Android is a smart mobile terminal operating platform core on Linux. But due to its open-source software and programmable framework character, it leads the Android system vulnerable to get virus attacks. This paper has deeply researched from the Linux system security mechanism, Android-specific security mechanisms and other protection mechanisms. And on this basis, Android devices have achieved closely guarded on normal state. So that attackers can not use the kernel module or core library to get highest access permission and be attacked. Meanwhile, to further strengthen the security of Android devices, it enables them to properly handle the high-risk threat. This paper also strengthened intrusion detection system (HIDS) based on the host in order to detect malicious software and strengthen the Android system-level access control.
