└─>Security options
└─>Enable introspection of sha256 hashes for loaded profiles
In linux kernel since version 3.10 (release Date: 2013-06-30)  
This option selects whether introspection of loaded policy
hashes is available to userspace via the apparmor
filesystem. This option provides a light weight means of
checking loaded policy. This option adds to policy load
time and can be disabled for small embedded systems.
