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
13 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
17 For example:
18
19 ps -eZ | grep prelude_t
20
21
22
24 The prelude_t SELinux type can be entered via the prelude_exec_t file
25 type.
26
27 The default entrypoint paths for the prelude_t domain are the follow‐
28 ing:
29
30 /usr/bin/prelude-manager
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 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
42 The following process types are defined for prelude:
43
44 prelude_t, prelude_audisp_t, prelude_correlator_t, prelude_lml_t
45
46 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
51
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
58
59
60 If you want to dontaudit all daemons scheduling requests (setsched,
61 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
62 Enabled by default.
63
64 setsebool -P daemons_dontaudit_scheduling 1
65
66
67
68 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
71 setsebool -P fips_mode 1
72
73
74
75 If you want to allow system to run with NIS, you must turn on the
76 nis_enabled boolean. Disabled by default.
77
78 setsebool -P nis_enabled 1
79
80
81
83 SELinux defines port types to represent TCP and UDP ports.
84
85 You can see the types associated with a port by using the following
86 command:
87
88 semanage port -l
89
90
91 Policy governs the access confined processes have to these ports.
92 SELinux prelude policy is very flexible allowing users to setup their
93 prelude processes in as secure a method as possible.
94
95 The following port types are defined for prelude:
96
97
98 prelude_port_t
99
100
101
102 Default Defined Ports:
103 tcp 4690
104 udp 4690
105
107 The SELinux process type prelude_t can manage files labeled with the
108 following file types. The paths listed are the default paths for these
109 file types. Note the processes UID still need to have DAC permissions.

176 SELinux requires files to have an extended attribute to define the file
177 type.
178
179 You can see the context of a file using the -Z option to ls
180
181 Policy governs the access confined processes have to these files.
182 SELinux prelude policy is very flexible allowing users to setup their
183 prelude processes in as secure a method as possible.
184
185 EQUIVALENCE DIRECTORIES
186
187
188 prelude policy stores data with multiple different file context types
189 under the /var/spool/prelude directory. If you would like to store the
190 data in a different directory you can use the semanage command to cre‐
191 ate an equivalence mapping. If you wanted to store this data under the
192 /srv directory you would execute the following command:
193
194 semanage fcontext -a -e /var/spool/prelude /srv/prelude
195 restorecon -R -v /srv/prelude
196
197 STANDARD FILE CONTEXT
198
199 SELinux defines the file context types for the prelude, if you wanted
200 to store files with these types in a different paths, you need to exe‐
201 cute the semanage command to specify alternate labeling and then use
202 restorecon to put the labels on disk.
203
204 semanage fcontext -a -t prelude_exec_t '/srv/prelude/content(/.*)?'
205 restorecon -R -v /srv/myprelude_content
206
207 Note: SELinux often uses regular expressions to specify labels that
208 match multiple files.
209
210 The following file types are defined for prelude:
211
212
213
214 prelude_audisp_exec_t

239 prelude_correlator_exec_t
240
241 - Set files with the prelude_correlator_exec_t type, if you want to

249 executable to the prelude_t domain.
250
251
252
253 prelude_initrc_exec_t
254
255 - Set files with the prelude_initrc_exec_t type, if you want to transi‐
256 tion an executable to the prelude_initrc_t domain.
257
258
259 Paths:
260 /etc/rc.d/init.d/prelude-lml, /etc/rc.d/init.d/prelude-manager,
261 /etc/rc.d/init.d/prelude-correlator
262
263
264 prelude_lml_exec_t

274 lude lml temporary files in the /tmp directories.
275
276
277
278 prelude_lml_var_run_t
279
280 - Set files with the prelude_lml_var_run_t type, if you want to store
281 the prelude lml files under the /run or /var/run directory.
282
283
284
285 prelude_log_t
286
287 - Set files with the prelude_log_t type, if you want to treat the data
288 as prelude log data, usually stored under the /var/log directory.
289
290
291
292 prelude_spool_t
293

312 prelude files under the /run or /var/run directory.
313
314
315
316 Note: File context can be temporarily modified with the chcon command.
317 If you want to permanently change the file context you need to use the
318 semanage fcontext command. This will modify the SELinux labeling data‐
319 base. You will need to use restorecon to apply the labels.
320
321
323 semanage fcontext can also be used to manipulate default file context
324 mappings.
325
326 semanage permissive can also be used to manipulate whether or not a
327 process type is permissive.
328
329 semanage module can also be used to enable/disable/install/remove pol‐
330 icy modules.
331
332 semanage port can also be used to manipulate the port definitions
333
334 semanage boolean can also be used to manipulate the booleans
335
336
337 system-config-selinux is a GUI tool available to customize SELinux pol‐
338 icy settings.
