prelude_selinux(8) prelude SELinux Policy documentation prelude_selinux(8)NAMEprelude_selinux - Security Enhanced Linux Policy for the prelude pro‐
cesses
DESCRIPTION
Security-Enhanced Linux secures the prelude processes via flexible
mandatory access control.
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the pre‐
lude_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 allow_kerberos boolean.
setsebool -P allow_kerberos 1
If you want to allow system to run with NI for the prelude_lml_t, pre‐
lude_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 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 transi‐
tion an executable to the prelude_audisp_t domain.
Paths:
/sbin/audisp-prelude, /usr/sbin/audisp-prelude
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 transi‐
tion an executable to the prelude_initrc_t domain.
Paths:
/etc/rc.d/init.d/prelude-correlator, /etc/rc.d/init.d/prelude-man‐
ager, /etc/rc.d/init.d/prelude-lml
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 pre‐
lude 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.
Paths:
/var/spool/prelude(/.*)?, /var/spool/prelude-manager(/.*)?
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 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.
PORT TYPES
SELinux defines port types to represent TCP and UDP ports.
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 prelude policy is very flexible allowing users to setup their
prelude processes in as secure a method as possible.
The following port types are defined for prelude:
prelude_port_t
Default Defined Ports:
tcp 4690
udp 4690
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
prelude policy is very flexible allowing users to setup their prelude
processes in as secure a method as possible.
The following process types are defined for prelude:
prelude_lml_t, prelude_t, prelude_audisp_t, prelude_correlator_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.
semanage port can also be used to manipulate the port definitions
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
