Yama is a new security module that comes with the Linux kernel. Yama is not yet considered a standard LSM module, but in the future, it may be the fifth standard LSM module. Yama uses the same principals as the other security modules.
Yama is a Linux Security Module that collects a number of system-wide DAC security protections that are not handled by the core kernel itself. To select it at boot time, specify "security=yama" (though this will disable
any other LSM).
Yama is controlled through sysctl in /proc/sys/kernel/yama
