Security-Enhanced Linux secures the munin processes via flexible mandatory access control.
If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd serve for the munin_t, you must turn on the authlogin_nsswitch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the munin_t, you must turn on the kerberos_enabled boolean.
setsebool -P kerberos_enabled 1
You can see the context of a file using the -Z option to lsP Policy governs the access confined processes have to these files. SELinux munin policy is very flexible allowing users to setup their munin processes in as secure a method as possible.
The following file types are defined for munin:
munin_etc_t
- Set files with the munin_etc_t type, if you want to store munin files in the /etc directories.
munin_exec_t
- Set files with the munin_exec_t type, if you want to transition an executable to the munin_t domain.
munin_initrc_exec_t
- Set files with the munin_initrc_exec_t type, if you want to transition an executable to the munin_initrc_t domain.
munin_log_t
- Set files with the munin_log_t type, if you want to treat the data as munin log data, usually stored under the /var/log directory.
munin_plugin_state_t
- Set files with the munin_plugin_state_t type, if you want to treat the files as munin plugin state data.
munin_tmp_t
- Set files with the munin_tmp_t type, if you want to store munin temporary files in the /tmp directories.
munin_var_lib_t
- Set files with the munin_var_lib_t type, if you want to store the munin files under the /var/lib directory.
munin_var_run_t
- Set files with the munin_var_run_t type, if you want to store the munin files under the /run directory.
Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.
You can see the types associated with a port by using the following command:
semanage port -l
Policy governs the access confined processes have to these ports. SELinux munin policy is very flexible allowing users to setup their munin processes in as secure a method as possible.
The following port types are defined for munin:
Default Defined Ports: tcp 4949 udp 4949
You can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux munin policy is very flexible allowing users to setup their munin processes in as secure a method as possible.
The following process types are defined for munin:
munin_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.
The SELinux user type munin_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.
