DESCRIPTION
Security-Enhanced Linux secures the nut processes via flexible manda‐
tory access control.
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the
nut_upsmon_t, nut_upsdrvctl_t, nut_upsd_t, you must turn on the authlo‐
gin_nsswitch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the
nut_upsmon_t, nut_upsdrvctl_t, nut_upsd_t, you must turn on the
allow_kerberos boolean.
setsebool -P allow_kerberos 1
If you want to allow system to run with NI for the nut_upsmon_t,
nut_upsdrvctl_t, nut_upsd_t, you must turn on the allow_ypbind boolean.
setsebool -P allow_ypbind 1
FILE CONTEXTS
SELinux requires files to have an extended attribute to define the file
type.
You can see the context of a file using the -Z option to ls
Policy governs the access confined processes have to these files.
SELinux nut policy is very flexible allowing users to setup their nut
processes in as secure a method as possible.
The following file types are defined for nut:
nut_conf_t
- Set files with the nut_conf_t type, if you want to treat the files as
nut configuration data, usually stored under the /etc directory.
nut_upsd_exec_t
- Set files with the nut_upsd_exec_t type, if you want to transition an
executable to the nut_upsd_t domain.
nut_upsdrvctl_exec_t
- Set files with the nut_upsdrvctl_exec_t type, if you want to transi‐
tion an executable to the nut_upsdrvctl_t domain.
Paths:
/usr/sbin/upsdrvctl, /sbin/upsdrvctl
nut_upsmon_exec_t
- Set files with the nut_upsmon_exec_t type, if you want to transition
an executable to the nut_upsmon_t domain.
nut_var_run_t
- Set files with the nut_var_run_t type, if you want to store the nut
files under the /run directory.
Note: File context can be temporarily modified with the chcon command.
If you want to permanantly change the file context you need to use the
semanage fcontext command. This will modify the SELinux labeling data‐
base. You will need to use restorecon to apply the labels.
PROCESS TYPES
SELinux defines process types (domains) for each process running on the
system
You can see the context of a process using the -Z option to ps
Policy governs the access confined processes have to files. SELinux
nut policy is very flexible allowing users to setup their nut processes
in as secure a method as possible.
The following process types are defined for nut:
nut_upsd_t, nut_upsmon_t, nut_upsdrvctl_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process
type permissive. Permissive process types are not denied access by
SELinux. AVC messages will still be generated.
COMMANDS
semanage fcontext can also be used to manipulate default file context
mappings.
semanage permissive can also be used to manipulate whether or not a
process type is permissive.
semanage module can also be used to enable/disable/install/remove pol‐
icy modules.
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
