6 prelude_selinux - Security Enhanced Linux Policy for the prelude pro‐
7 cesses
8
10 Security-Enhanced Linux secures the prelude processes via flexible
11 mandatory access control.
12 The prelude processes execute with the prelude_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16 For example:
18 ps -eZ | grep prelude_t
20
24 The prelude_t SELinux type can be entered via the prelude_exec_t file
25 type.
26 The default entrypoint paths for the prelude_t domain are the follow‐
28 ing:
29 /usr/bin/prelude-manager
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 prelude policy is very flexible allowing users to setup their prelude
40 processes in as secure a method as possible.
41 The following process types are defined for prelude:
43 prelude_t, prelude_audisp_t, prelude_correlator_t, prelude_lml_t
45 Note: semanage permissive -a prelude_t can be used to make the process
47 type prelude_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
53 SELinux policy is customizable based on least access required. prelude
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run prelude with the tightest access possi‐
56 ble.
57 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63 setsebool -P authlogin_nsswitch_use_ldap 1
65 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70 setsebool -P fips_mode 1
72 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Enabled by default.
77 setsebool -P kerberos_enabled 1
79 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84 setsebool -P nis_enabled 1
86 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Enabled by default.
91 setsebool -P nscd_use_shm 1
93
97 SELinux defines port types to represent TCP and UDP ports.
98 You can see the types associated with a port by using the following
100 command:
101 semanage port -l
103 Policy governs the access confined processes have to these ports.
106 SELinux prelude policy is very flexible allowing users to setup their
107 prelude processes in as secure a method as possible.
108 The following port types are defined for prelude:
110 prelude_port_t
113 Default Defined Ports:
117 tcp 4690
118 udp 4690
119
121 The SELinux process type prelude_t can manage files labeled with the
122 following file types. The paths listed are the default paths for these
123 file types. Note the processes UID still need to have DAC permissions.

178 SELinux requires files to have an extended attribute to define the file
179 type.
180 You can see the context of a file using the -Z option to ls
182 Policy governs the access confined processes have to these files.
184 SELinux prelude policy is very flexible allowing users to setup their
185 prelude processes in as secure a method as possible.
186 EQUIVALENCE DIRECTORIES
188 prelude policy stores data with multiple different file context types
191 under the /var/spool/prelude directory. If you would like to store the
192 data in a different directory you can use the semanage command to cre‐
193 ate an equivalence mapping. If you wanted to store this data under the
194 /srv dirctory you would execute the following command:
195 semanage fcontext -a -e /var/spool/prelude /srv/prelude
197 restorecon -R -v /srv/prelude
198 STANDARD FILE CONTEXT
200 SELinux defines the file context types for the prelude, if you wanted
202 to store files with these types in a diffent paths, you need to execute
203 the semanage command to sepecify alternate labeling and then use
204 restorecon to put the labels on disk.
205 semanage fcontext -a -t prelude_lml_var_run_t '/srv/myprelude_con‐
207 tent(/.*)?'
208 restorecon -R -v /srv/myprelude_content
209 Note: SELinux often uses regular expressions to specify labels that
211 match multiple files.
212 The following file types are defined for prelude:
214 prelude_audisp_exec_t
218 - Set files with the prelude_audisp_exec_t type, if you want to transi‐
220 tion an executable to the prelude_audisp_t domain.
221 Paths:
224 /sbin/audisp-prelude, /usr/sbin/audisp-prelude
225 prelude_audisp_var_run_t
228 - Set files with the prelude_audisp_var_run_t type, if you want to
230 store the prelude audisp files under the /run or /var/run directory.
231 prelude_correlator_config_t
235 - Set files with the prelude_correlator_config_t type, if you want to
237 treat the files as prelude correlator configuration data, usually
238 stored under the /etc directory.
239 prelude_correlator_exec_t
243 - Set files with the prelude_correlator_exec_t type, if you want to
245 transition an executable to the prelude_correlator_t domain.
246 prelude_exec_t
250 - Set files with the prelude_exec_t type, if you want to transition an
252 executable to the prelude_t domain.
253 prelude_initrc_exec_t
257 - Set files with the prelude_initrc_exec_t type, if you want to transi‐
259 tion an executable to the prelude_initrc_t domain.
260 Paths:
263 /etc/rc.d/init.d/prelude-lml, /etc/rc.d/init.d/prelude-manager,
264 /etc/rc.d/init.d/prelude-correlator
265 prelude_lml_exec_t
268 - Set files with the prelude_lml_exec_t type, if you want to transition
270 an executable to the prelude_lml_t domain.
271 prelude_lml_tmp_t
275 - Set files with the prelude_lml_tmp_t type, if you want to store pre‐
277 lude lml temporary files in the /tmp directories.
278 prelude_lml_var_run_t
282 - Set files with the prelude_lml_var_run_t type, if you want to store
284 the prelude lml files under the /run or /var/run directory.
285 prelude_log_t
289 - Set files with the prelude_log_t type, if you want to treat the data
291 as prelude log data, usually stored under the /var/log directory.
292 prelude_spool_t
296 - Set files with the prelude_spool_t type, if you want to store the
298 prelude files under the /var/spool directory.
299 Paths:
302 /var/spool/prelude(/.*)?, /var/spool/prelude-manager(/.*)?
303 prelude_var_lib_t
306 - Set files with the prelude_var_lib_t type, if you want to store the
308 prelude files under the /var/lib directory.
309 prelude_var_run_t
313 - Set files with the prelude_var_run_t type, if you want to store the
315 prelude files under the /run or /var/run directory.
316 Note: File context can be temporarily modified with the chcon command.
320 If you want to permanently change the file context you need to use the
321 semanage fcontext command. This will modify the SELinux labeling data‐
322 base. You will need to use restorecon to apply the labels.
323
326 semanage fcontext can also be used to manipulate default file context
327 mappings.
328 semanage permissive can also be used to manipulate whether or not a
330 process type is permissive.
331 semanage module can also be used to enable/disable/install/remove pol‐
333 icy modules.
334 semanage port can also be used to manipulate the port definitions
336 semanage boolean can also be used to manipulate the booleans
338 system-config-selinux is a GUI tool available to customize SELinux pol‐
341 icy settings.
