android hal selinux

Android HAL (Hardware Abstraction Layer) is a software component that provides a standardized interface for the Android OS to communicate with hardware components such as camera, sensors, and audio.

SELinux (Security-Enhanced Linux) is a security mechanism used in Android that enforces mandatory access control policies. It provides a kernel-level security layer that restricts access to system resources and prevents unauthorized access to sensitive data.

In Android, the HAL and SELinux work together to ensure that only authorized processes can access hardware components and system resources. The HAL provides a standardized interface for the Android OS to communicate with hardware, while SELinux enforces mandatory access control policies to prevent unauthorized access to system resources. This helps to improve the overall security and stability of the Android system.
