Prepare the System to get more verbose description what is missing on RC you should set this debug options. Append in the ``/boot/grub/menu.lst`` for the used rsbac-kernel on line ``kernel``

rsbac_softmode rsbac_nosyslog rsbac_cap_process_hiding rsbac_debug_adf_auth rsbac_debug_adf_rc rsbac_debug_adf_jail rsbac_debug_adf_um rsbac_debug_jail_log_missing_rbsac_debug_cap_log_missing 

This can enter on grubs promt too.

Default RSBAC with RC module is used this roles:

• Gerneral_User 0
• Role_Admin 1
• System_Admin 2
• Auditor 3

to run the system.

The permission for this roles are hardcoded in RSBAC code itself. Otherwise the system wont work. Bevor set any specific RC role for a service you can detach the default running ``Boot-Role``. For this you can create a Role ``Init``.

On a binary are always two roles, an initial- and force-role.
The initial-role is used to start a service, for this its need permission to read the necessary configurationfiles.
The force-role is used to run this service, there is usally no reason for permission to read the configurationfiles as example.

However, if a service not chown to other user, the process is running alway with the initial-role. This is surly the case for the init process. So thatswhy this setup firstly.

The ``init`` never change to a force role so no reason to build such one.

Now i start and do this: set a rc-role named ``Init`` as initial-role on ``/sbin/init``.

see setup: RC role for init process

rc_set_item ROpLE 4 name "Init"
attr_set_file_dir FILE "/sbin/init" rc_initial_role 4

Create two new ``rc_type_fd``

rc_set_item TYPE 4 type_fd_name "VarLog_FD"
rc_set_item TYPE 5 type_fd_name "VarRun_FD"  

Assign this to ``/var/log`` and ``/var/run``.

attr_set_file_dir DIR "/var/log" rc_type_fd 4
attr_set_file_dir DIR "/var/run" rc_type_fd 5

After reboot the system, the logfile print such:

To obtain a rigth of privacy Iam associate the rc-type with rc-role and set the rc-type-fd on users homedirectory.

My System has a security user which has ``uid`` and ``gid`` 400 and its homedirectory is situated on ``/security``.

Security-User

attr_set_file_dir DIR "/security" rc_type_fd 1

This protects for visiting the rootuser this directory. Create a new ``rc_type_group`` for group.

rc_set_item TYPE 1 type_group_name "Security_Group"

Now i apply this ``rc_types`` to RC role 1

rc_set_item ROLE 1 def_fd_create_type 1
rc_set_item ROLE 1 def_fd_ind_create_type 1 1
rc_set_item ROLE 1 def_user_create_type 1

Root-user

The same Iam doing for the rootuser directory.

attr_set_file_dir DIR "/root" rc_type_fd 2
