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

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

Answer: (A)

SEAndroid is the Android-specific implementation of SELinux, bringing mandatory access control into the Android environment. It applies tailored security policies that define how Android processes and apps (domains) interact with each other and with system resources (types), labeling objects and enforcing what each domain can access. This confinement helps enforce least privilege and strong isolation between apps and between apps and system components, covering file access, IPC, content providers, services, and more within Android's architecture. SELinux is the broader Linux MAC framework, not the Android-specific extension. Trusted Solaris is a separate security model for Solaris environments, and a kernel, while central to the operating system, is not the Android-specific mechanism that extends SELinux-style security.
