Which concept extends SELinux-style security into the Android environment?

• A. SEAndroid
• B. SELinux
• C. Trusted Solaris
• D. Kernel

Answer: (A)

SEAndroid is the extension of SELinux security into the Android environment. SELinux provides a mandatory access control framework that enforces policies to govern what processes can do on a system. Android takes that framework and tailors it to its own architecture, integrating it into the Android kernel and system services so that apps, processes, files, and inter-process communication are all subject to strict, policy-driven controls. This means even if an app tries to overstep its permissions, the SEAndroid policies constrain those actions, helping to contain damage and enforce least privilege across the platform. In contrast, SELinux refers to the general Linux security feature, Trusted Solaris is a separate security architecture for Solaris, and the kernel itself is the core of the operating system rather than the Android-specific security extension.
