nagios_selinux(8) nagios SELinux Policy documentation nagios_selinux(8)NAMEnagios_selinux - Security Enhanced Linux Policy for the nagios pro‐
cesses
DESCRIPTION
Security-Enhanced Linux secures the nagios processes via flexible
mandatory access control.
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the
nagios_services_plugin_t, nagios_t, you must turn on the authlogin_nss‐
witch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the
nagios_services_plugin_t, nagios_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 nagios_ser‐
vices_plugin_t, nagios_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 nagios policy is very flexible allowing users to setup their
nagios processes in as secure a method as possible.
The following file types are defined for nagios:
nagios_admin_plugin_exec_t
- Set files with the nagios_admin_plugin_exec_t type, if you want to
transition an executable to the nagios_admin_plugin_t domain.
nagios_checkdisk_plugin_exec_t

to transition an executable to the nagios_checkdisk_plugin_t domain.

as nagios log data, usually stored under the /var/log directory.

nagios_mail_plugin_exec_t
- Set files with the nagios_mail_plugin_exec_t type, if you want to
transition an executable to the nagios_mail_plugin_t domain.

- Set files with the nagios_services_plugin_exec_t type, if you want to
transition an executable to the nagios_services_plugin_t domain.

nagios_spool_t
- Set files with the nagios_spool_t type, if you want to store the
nagios files under the /var/spool directory.
nagios_system_plugin_exec_t
- Set files with the nagios_system_plugin_exec_t type, if you want to
transition an executable to the nagios_system_plugin_t domain.

nagios_system_plugin_tmp_t
- Set files with the nagios_system_plugin_tmp_t type, if you want to
store nagios system plugin temporary files in the /tmp directories.

temporary files in the /tmp directories.
nagios_unconfined_plugin_exec_t
- Set files with the nagios_unconfined_plugin_exec_t type, if you want
to transition an executable to the nagios_unconfined_plugin_t domain.
nagios_var_lib_t
- Set files with the nagios_var_lib_t type, if you want to store the
nagios files under the /var/lib directory.
nagios_var_run_t
- Set files with the nagios_var_run_t type, if you want to store the
nagios 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
nagios policy is very flexible allowing users to setup their nagios
processes in as secure a method as possible.
The following process types are defined for nagios:
nagios_t, nagios_mail_plugin_t, nagios_checkdisk_plugin_t, nagios_services_plugin_t, nagios_eventhandler_plugin_t, nagios_system_plugin_t, nagios_unconfined_plugin_t, nagios_admin_plugin_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.
