6 cgred_selinux - Security Enhanced Linux Policy for the cgred processes
7
9 Security-Enhanced Linux secures the cgred processes via flexible manda‐
10 tory access control.
11
12 The cgred processes execute with the cgred_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep cgred_t
19
20
21
23 The cgred_t SELinux type can be entered via the cgred_exec_t file type.
24
25 The default entrypoint paths for the cgred_t domain are the following:
26
27 /sbin/cgrulesengd
28
30 SELinux defines process types (domains) for each process running on the
31 system
32
33 You can see the context of a process using the -Z option to ps
34
35 Policy governs the access confined processes have to files. SELinux
36 cgred policy is very flexible allowing users to setup their cgred pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for cgred:
40
41 cgred_t
42
43 Note: semanage permissive -a cgred_t can be used to make the process
44 type cgred_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
48
50 SELinux policy is customizable based on least access required. cgred
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run cgred with the tightest access possible.

150 The SELinux process type cgred_t can manage files labeled with the fol‐
151 lowing file types. The paths listed are the default paths for these
152 file types. Note the processes UID still need to have DAC permissions.

225 SELinux requires files to have an extended attribute to define the file
226 type.
227
228 You can see the context of a file using the -Z option to ls
229
230 Policy governs the access confined processes have to these files.
231 SELinux cgred policy is very flexible allowing users to setup their
232 cgred processes in as secure a method as possible.
233
234 STANDARD FILE CONTEXT
235
236 SELinux defines the file context types for the cgred, if you wanted to
237 store files with these types in a diffent paths, you need to execute
238 the semanage command to sepecify alternate labeling and then use
239 restorecon to put the labels on disk.
240
241 semanage fcontext -a -t cgred_var_run_t '/srv/mycgred_content(/.*)?'
242 restorecon -R -v /srv/mycgred_content
243
244 Note: SELinux often uses regular expressions to specify labels that
245 match multiple files.
246
247 The following file types are defined for cgred:
248
249
250
251 cgred_exec_t
252
253 - Set files with the cgred_exec_t type, if you want to transition an
254 executable to the cgred_t domain.
255
256
257
258 cgred_initrc_exec_t
259
260 - Set files with the cgred_initrc_exec_t type, if you want to transi‐
261 tion an executable to the cgred_initrc_t domain.
262
263
264
265 cgred_log_t
266
267 - Set files with the cgred_log_t type, if you want to treat the data as
268 cgred log data, usually stored under the /var/log directory.
269
270
271
272 cgred_var_run_t
273
274 - Set files with the cgred_var_run_t type, if you want to store the
275 cgred files under the /run or /var/run directory.
276
277
278
279 Note: File context can be temporarily modified with the chcon command.
280 If you want to permanently change the file context you need to use the
281 semanage fcontext command. This will modify the SELinux labeling data‐
282 base. You will need to use restorecon to apply the labels.
283
284
286 semanage fcontext can also be used to manipulate default file context
287 mappings.
288
289 semanage permissive can also be used to manipulate whether or not a
290 process type is permissive.
291
292 semanage module can also be used to enable/disable/install/remove pol‐
293 icy modules.
294
295 semanage boolean can also be used to manipulate the booleans
296
297
298 system-config-selinux is a GUI tool available to customize SELinux pol‐
299 icy settings.
