Security-Enhanced Linux secures the prelude 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 prelude_lml_t, prelude_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 prelude_lml_t, prelude_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 prelude policy is very flexible allowing users to setup their prelude processes in as secure a method as possible.
The following file types are defined for prelude:
prelude_audisp_exec_t
- Set files with the prelude_audisp_exec_t type, if you want to transition an executable to the prelude_audisp_t domain.
prelude_audisp_var_run_t
- Set files with the prelude_audisp_var_run_t type, if you want to store the prelude audisp files under the /run directory.
prelude_correlator_config_t
- Set files with the prelude_correlator_config_t type, if you want to treat the files as prelude correlator configuration data, usually stored under the /etc directory.
prelude_correlator_exec_t
- Set files with the prelude_correlator_exec_t type, if you want to transition an executable to the prelude_correlator_t domain.
prelude_exec_t
- Set files with the prelude_exec_t type, if you want to transition an executable to the prelude_t domain.
prelude_initrc_exec_t
- Set files with the prelude_initrc_exec_t type, if you want to transition an executable to the prelude_initrc_t domain.
prelude_lml_exec_t
- Set files with the prelude_lml_exec_t type, if you want to transition an executable to the prelude_lml_t domain.
prelude_lml_tmp_t
- Set files with the prelude_lml_tmp_t type, if you want to store prelude lml temporary files in the /tmp directories.
prelude_lml_var_run_t
- Set files with the prelude_lml_var_run_t type, if you want to store the prelude lml files under the /run directory.
prelude_log_t
- Set files with the prelude_log_t type, if you want to treat the data as prelude log data, usually stored under the /var/log directory.
prelude_spool_t
- Set files with the prelude_spool_t type, if you want to store the prelude files under the /var/spool directory.
prelude_var_lib_t
- Set files with the prelude_var_lib_t type, if you want to store the prelude files under the /var/lib directory.
prelude_var_run_t
- Set files with the prelude_var_run_t type, if you want to store the prelude 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
