Google has decided to take more security measures to enable present in Linux in Android, to protect users so better against different types of attacks. This relates to measures to reduce the attack surface and should protect the memory.
The Android security model is largely based on the Linux kernel. To better protect Android Google has more of these measures enabled. One of the measures, for example, ensures that the Android kernel has no access to “user space” memory. This allows performing various attacks much more difficult, because the attackers gives much less control over the kernel memory which they can execute their own code.
There are also measures implemented against vulnerabilities such as buffer overflows must protect and additional sandboxing is applied. According to Jeff Vander Stoep of the Android security team there are several projects within Google actively to protect the Android kernel, including a project to strengthen the sandbox security and projects to determine the origin of crashes. “Through this and other projects we expect the kernel security will continue to improve,” said Vander Stoep.
