6 openwsman_selinux - Security Enhanced Linux Policy for the openwsman
7 processes
8
10 Security-Enhanced Linux secures the openwsman processes via flexible
11 mandatory access control.
12
13 The openwsman processes execute with the openwsman_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep openwsman_t
20
21
22
24 The openwsman_t SELinux type can be entered via the openwsman_exec_t
25 file type.
26
27 The default entrypoint paths for the openwsman_t domain are the follow‐
28 ing:
29
30 /usr/sbin/openwsmand
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 openwsman policy is very flexible allowing users to setup their openws‐
40 man processes in as secure a method as possible.
41
42 The following process types are defined for openwsman:
43
44 openwsman_t
45
46 Note: semanage permissive -a openwsman_t can be used to make the
47 process type openwsman_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required. openws‐
54 man policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run openwsman with the tightest access
56 possible.

237
239 The SELinux process type openwsman_t can manage files labeled with the
240 following file types. The paths listed are the default paths for these
241 file types. Note the processes UID still need to have DAC permissions.
242
243 file_type
244
245 all files on the system
246
247
249 SELinux requires files to have an extended attribute to define the file
250 type.
251
252 You can see the context of a file using the -Z option to ls
253
254 Policy governs the access confined processes have to these files.
255 SELinux openwsman policy is very flexible allowing users to setup their
256 openwsman processes in as secure a method as possible.
257
258 STANDARD FILE CONTEXT
259
260 SELinux defines the file context types for the openwsman, if you wanted
261 to store files with these types in a diffent paths, you need to execute
262 the semanage command to sepecify alternate labeling and then use
263 restorecon to put the labels on disk.
264
265 semanage fcontext -a -t openwsman_unit_file_t '/srv/myopenwsman_con‐
266 tent(/.*)?'
267 restorecon -R -v /srv/myopenwsman_content
268
269 Note: SELinux often uses regular expressions to specify labels that
270 match multiple files.
271
272 The following file types are defined for openwsman:
273
274
275
276 openwsman_exec_t
277
278 - Set files with the openwsman_exec_t type, if you want to transition
279 an executable to the openwsman_t domain.
280
281
282
283 openwsman_log_t
284
285 - Set files with the openwsman_log_t type, if you want to treat the
286 data as openwsman log data, usually stored under the /var/log direc‐
287 tory.
288
289
290
291 openwsman_run_t
292
293 - Set files with the openwsman_run_t type, if you want to treat the
294 files as openwsman run data.
295
296
297
298 openwsman_tmp_t
299
300 - Set files with the openwsman_tmp_t type, if you want to store openws‐
301 man temporary files in the /tmp directories.
302
303
304
305 openwsman_tmpfs_t
306
307 - Set files with the openwsman_tmpfs_t type, if you want to store open‐
308 wsman files on a tmpfs file system.
309
310
311
312 openwsman_unit_file_t
313
314 - Set files with the openwsman_unit_file_t type, if you want to treat
315 the files as openwsman unit content.
316
317
318
319 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
324
326 semanage fcontext can also be used to manipulate default file context
327 mappings.
328
329 semanage permissive can also be used to manipulate whether or not a
330 process type is permissive.
331
332 semanage module can also be used to enable/disable/install/remove pol‐
333 icy modules.
334
335 semanage boolean can also be used to manipulate the booleans
336
337
338 system-config-selinux is a GUI tool available to customize SELinux pol‐
339 icy settings.
