6 lwiod_selinux - Security Enhanced Linux Policy for the lwiod processes
7
9 Security-Enhanced Linux secures the lwiod processes via flexible manda‐
10 tory access control.
11
12 The lwiod processes execute with the lwiod_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 lwiod_t
19
20
21
23 The lwiod_t SELinux type can be entered via the lwiod_exec_t file type.
24
25 The default entrypoint paths for the lwiod_t domain are the following:
26
27 /usr/sbin/lwiod
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 lwiod policy is very flexible allowing users to setup their lwiod pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for lwiod:
40
41 lwiod_t
42
43 Note: semanage permissive -a lwiod_t can be used to make the process
44 type lwiod_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. lwiod
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run lwiod with the tightest access possible.

132
133
134
136 The SELinux process type lwiod_t can manage files labeled with the fol‐
137 lowing file types. The paths listed are the default paths for these
138 file types. Note the processes UID still need to have DAC permissions.

210 SELinux requires files to have an extended attribute to define the file
211 type.
212
213 You can see the context of a file using the -Z option to ls
214
215 Policy governs the access confined processes have to these files.
216 SELinux lwiod policy is very flexible allowing users to setup their
217 lwiod processes in as secure a method as possible.
218
219 STANDARD FILE CONTEXT
220
221 SELinux defines the file context types for the lwiod, if you wanted to
222 store files with these types in a diffent paths, you need to execute
223 the semanage command to sepecify alternate labeling and then use
224 restorecon to put the labels on disk.
225
226 semanage fcontext -a -t lwiod_var_socket_t '/srv/mylwiod_content(/.*)?'
227 restorecon -R -v /srv/mylwiod_content
228
229 Note: SELinux often uses regular expressions to specify labels that
230 match multiple files.
231
232 The following file types are defined for lwiod:
233
234
235
236 lwiod_exec_t
237
238 - Set files with the lwiod_exec_t type, if you want to transition an
239 executable to the lwiod_t domain.
240
241
242
243 lwiod_var_lib_t
244
245 - Set files with the lwiod_var_lib_t type, if you want to store the
246 lwiod files under the /var/lib directory.
247
248
249
250 lwiod_var_run_t
251
252 - Set files with the lwiod_var_run_t type, if you want to store the
253 lwiod files under the /run or /var/run directory.
254
255
256
257 lwiod_var_socket_t
258
259 - Set files with the lwiod_var_socket_t type, if you want to treat the
260 files as lwiod var socket data.
261
262
263
264 Note: File context can be temporarily modified with the chcon command.
265 If you want to permanently change the file context you need to use the
266 semanage fcontext command. This will modify the SELinux labeling data‐
267 base. You will need to use restorecon to apply the labels.
268
269
271 semanage fcontext can also be used to manipulate default file context
272 mappings.
273
274 semanage permissive can also be used to manipulate whether or not a
275 process type is permissive.
276
277 semanage module can also be used to enable/disable/install/remove pol‐
278 icy modules.
279
280 semanage boolean can also be used to manipulate the booleans
281
282
283 system-config-selinux is a GUI tool available to customize SELinux pol‐
284 icy settings.
