6 jabberd_selinux - Security Enhanced Linux Policy for the jabberd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the jabberd processes via flexible
11 mandatory access control.
12
13 The jabberd processes execute with the jabberd_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 jabberd_t
20
21
22
24 The jabberd_t SELinux type can be entered via the jabberd_exec_t file
25 type.
26
27 The default entrypoint paths for the jabberd_t domain are the follow‐
28 ing:
29
30 /usr/bin/sm, /usr/bin/s2s
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 jabberd policy is very flexible allowing users to setup their jabberd
40 processes in as secure a method as possible.
41
42 The following process types are defined for jabberd:
43
44 jabberd_t, jabberd_router_t
45
46 Note: semanage permissive -a jabberd_t can be used to make the process
47 type jabberd_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. jabberd
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run jabberd with the tightest access possi‐
56 ble.

142 SELinux defines port types to represent TCP and UDP ports.
143
144 You can see the types associated with a port by using the following
145 command:
146
147 semanage port -l
148
149
150 Policy governs the access confined processes have to these ports.
151 SELinux jabberd policy is very flexible allowing users to setup their
152 jabberd processes in as secure a method as possible.
153
154 The following port types are defined for jabberd:
155
156
157 jabber_client_port_t
158
159
160
161 Default Defined Ports:
162 tcp 5222,5223

177 Default Defined Ports:
178 tcp 5347
179
181 The SELinux process type jabberd_t can manage files labeled with the
182 following file types. The paths listed are the default paths for these
183 file types. Note the processes UID still need to have DAC permissions.

226 SELinux requires files to have an extended attribute to define the file
227 type.
228
229 You can see the context of a file using the -Z option to ls
230
231 Policy governs the access confined processes have to these files.
232 SELinux jabberd policy is very flexible allowing users to setup their
233 jabberd processes in as secure a method as possible.
234
235 STANDARD FILE CONTEXT
236
237 SELinux defines the file context types for the jabberd, if you wanted
238 to store files with these types in a diffent paths, you need to execute
239 the semanage command to sepecify alternate labeling and then use
240 restorecon to put the labels on disk.
241
242 semanage fcontext -a -t jabberd_var_lib_t '/srv/myjabberd_con‐
243 tent(/.*)?'
244 restorecon -R -v /srv/myjabberd_content
245
246 Note: SELinux often uses regular expressions to specify labels that
247 match multiple files.
248
249 The following file types are defined for jabberd:
250
251
252
253 jabberd_exec_t
254
255 - Set files with the jabberd_exec_t type, if you want to transition an
256 executable to the jabberd_t domain.
257
258
259 Paths:
260 /usr/bin/sm, /usr/bin/s2s
261
262
263 jabberd_initrc_exec_t
264
265 - Set files with the jabberd_initrc_exec_t type, if you want to transi‐
266 tion an executable to the jabberd_initrc_t domain.
267
268
269
270 jabberd_router_exec_t
271
272 - Set files with the jabberd_router_exec_t type, if you want to transi‐
273 tion an executable to the jabberd_router_t domain.
274
275
276 Paths:
277 /usr/bin/c2s, /usr/bin/router
278
279
280 jabberd_var_lib_t
281
282 - Set files with the jabberd_var_lib_t type, if you want to store the
283 jabberd files under the /var/lib directory.
284
285
286
287 Note: File context can be temporarily modified with the chcon command.
288 If you want to permanently change the file context you need to use the
289 semanage fcontext command. This will modify the SELinux labeling data‐
290 base. You will need to use restorecon to apply the labels.
291
292
294 semanage fcontext can also be used to manipulate default file context
295 mappings.
296
297 semanage permissive can also be used to manipulate whether or not a
298 process type is permissive.
299
300 semanage module can also be used to enable/disable/install/remove pol‐
301 icy modules.
302
303 semanage port can also be used to manipulate the port definitions
304
305 semanage boolean can also be used to manipulate the booleans
306
307
308 system-config-selinux is a GUI tool available to customize SELinux pol‐
309 icy settings.
