As an operating system for mobile device,Google's Android-an open,programmable software framework-is vulnerable to typical smart-phone attacks.To date,there is no effective method available to prevent mobile threats,so mobile security still has a long way to go.Linux mechanism are introduced,Android-specific security mechanism and some other defense mechanisms,which may act as the defense mechanism of mobile security.An Android device in its normal state is well-guarded,however,it is possible for an attacker to identify vulnerability in one of the kernel modules or core libraries,acquire root access and carry out attack.So,to further harden Android devices and enable them to cope with high-risk threats,several security countermeasures are proposed.An overview of some of the most relevant approaches anchored in the area of machine learning is provided,anomaly detection,KBTA,as well as access control using SELinux.
