SEAndroid enhances the Android system by adding SELinux support to the kernel and user space to:
The security context of SEAndroid is basically consistent with SELinux. The four parts, user, role, type, sensitivity, i.e., u: object_r: system_data_file: s0 are described below:
- SELinux implementation to reduce attacks from vulnerabilities and malware
ChainFire opened up the current situation of rooting method on Android 5.0 Lollipop after Google used SELinux to improve security measures.
Apparently, the SELinux security implementation on the new Android operating system version also makes rooting access more difficult than before in addition to improving protection against attacks.
Additional security implementations such as SELinux enforcing against vulnerabilities and malware.
- SELinux enforcing for all apps to increase protection against malware attacks and vulnerabilities.
According to a report by (http://androidcommunity.com/chainfire-foresees-rooting-problems-in-upcoming-android-4-4-3-20140519/) Android Community , the perceived problems stem from the Android's SeLinux adoption.
