+
+What is AppArmor?
+=================
+
+AppArmor is MAC style security extension for the Linux kernel.  It implements
+a task centered policy, with task "profiles" being created and loaded
+from user space.  Tasks on the system that do not have a profile defined for
+them run in an unconfined state which is equivalent to standard Linux DAC
+permissions.
+
+How to enable/disable
+=====================
+
+set ``CONFIG_SECURITY_APPARMOR=y``
+
+If AppArmor should be selected as the default security module then set::
+
+   CONFIG_DEFAULT_SECURITY="apparmor"
+   CONFIG_SECURITY_APPARMOR_BOOTPARAM_VALUE=1
+
+Build the kernel
+
+If AppArmor is not the default security module it can be enabled by passing
+``security=apparmor`` on the kernel's command line.
+
+If AppArmor is the default security module it can be disabled by passing
+``apparmor=0, security=XXXX`` (where ``XXXX`` is valid security module), on the
+kernel's command line.
+
+For AppArmor to enforce any restrictions beyond standard Linux DAC permissions
+policy must be loaded into the kernel from user space (see the Documentation
+and tools links).
