ABSTRACT

As an important part of Android system security mechanism, SEAndroid is directly related to system security. Due to its open source, programmable software framework, and the nature of networked devices, Android is vulnerable to smartphone viruses. Android devices are tightly protected under normal conditions, but an attacker is likely to find weaknesses in a kernel module or core library to gain maximum access and attack. This paper starts with the system architecture of Android, analyzes the existing security mechanism and security risks of Android, and finally gives a security solution for security risks.
