Which term is associated with enforcing mandatory access control in Unix-like systems and is not Android-specific?

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

Answer: (A)

The concept here is enforcing strict security through Mandatory Access Control in Unix-like systems using a dedicated MAC framework. SELinux, Security-Enhanced Linux, is exactly that: a MAC subsystem built into the Linux kernel that enforces policies labeling subjects (like processes) and objects (like files) and dictating what actions are allowed. It provides fine-grained control beyond traditional Unix permissions, ensuring that even superusers can be restricted by policy rules.

This term is not Android-specific. Android uses SEAndroid, which is SELinux-based, but SEAndroid is the Android adaptation rather than the general Unix-like MAC framework. The other options point to different contexts: Trusted Solaris is a separate MAC implementation for the Solaris OS, and the kernel itself is the core of the OS, not a term for a MAC enforcement mechanism.
