Isaac wants to implement mandatory access controls on an Android-based device. What can he do to accomplish this?

SELinux enables mandatory access control for Linux-based systems, and SEAndroid is the implementation of SELinux for Android. As such, Isaac can utilize SEAndroid to achieve his objectives. While Android does employ a registry, it does not offer a MAC mode. It's worth noting that "MACDroid" is a term that was created for this question and is not commonly used in the industry. Additionally, the availability of single-user mode does not transform Android into a MAC-based system.
