6 asterisk_selinux - Security Enhanced Linux Policy for the asterisk pro‐
7 cesses
8
10 Security-Enhanced Linux secures the asterisk processes via flexible
11 mandatory access control.
12
13 The asterisk processes execute with the asterisk_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 asterisk_t
20
21
22
24 The asterisk_t SELinux type can be entered via the asterisk_exec_t file
25 type.
26
27 The default entrypoint paths for the asterisk_t domain are the follow‐
28 ing:
29
30 /usr/sbin/asterisk
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 asterisk policy is very flexible allowing users to setup their asterisk
40 processes in as secure a method as possible.
41
42 The following process types are defined for asterisk:
43
44 asterisk_t
45
46 Note: semanage permissive -a asterisk_t can be used to make the process
47 type asterisk_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. aster‐
54 isk policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run asterisk with the tightest access
56 possible.
57
58
59
60 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1
64
65
66
68 SELinux defines port types to represent TCP and UDP ports.
69
70 You can see the types associated with a port by using the following
71 command:
72
73 semanage port -l
74
75
76 Policy governs the access confined processes have to these ports.
77 SELinux asterisk policy is very flexible allowing users to setup their
78 asterisk processes in as secure a method as possible.
79
80 The following port types are defined for asterisk:
81
82
83 asterisk_port_t
84
85
86
87 Default Defined Ports:
88 tcp 1720
89 udp 2427,2727,4569
90
92 The SELinux process type asterisk_t can manage files labeled with the
93 following file types. The paths listed are the default paths for these
94 file types. Note the processes UID still need to have DAC permissions.

170 SELinux requires files to have an extended attribute to define the file
171 type.
172
173 You can see the context of a file using the -Z option to ls
174
175 Policy governs the access confined processes have to these files.
176 SELinux asterisk policy is very flexible allowing users to setup their
177 asterisk processes in as secure a method as possible.
178
179 STANDARD FILE CONTEXT
180
181 SELinux defines the file context types for the asterisk, if you wanted
182 to store files with these types in a diffent paths, you need to execute
183 the semanage command to sepecify alternate labeling and then use re‐
184 storecon to put the labels on disk.
185
186 semanage fcontext -a -t asterisk_var_run_t '/srv/myasterisk_con‐
187 tent(/.*)?'
188 restorecon -R -v /srv/myasterisk_content
189
190 Note: SELinux often uses regular expressions to specify labels that
191 match multiple files.
192
193 The following file types are defined for asterisk:
194
195
196
197 asterisk_etc_t
198
199 - Set files with the asterisk_etc_t type, if you want to store asterisk
200 files in the /etc directories.
201
202
203
204 asterisk_exec_t
205
206 - Set files with the asterisk_exec_t type, if you want to transition an
207 executable to the asterisk_t domain.
208
209
210
211 asterisk_initrc_exec_t
212
213 - Set files with the asterisk_initrc_exec_t type, if you want to tran‐
214 sition an executable to the asterisk_initrc_t domain.
215
216
217
218 asterisk_log_t
219
220 - Set files with the asterisk_log_t type, if you want to treat the data
221 as asterisk log data, usually stored under the /var/log directory.
222
223
224
225 asterisk_spool_t
226
227 - Set files with the asterisk_spool_t type, if you want to store the
228 asterisk files under the /var/spool directory.
229
230
231
232 asterisk_tmp_t
233
234 - Set files with the asterisk_tmp_t type, if you want to store asterisk
235 temporary files in the /tmp directories.
236
237
238
239 asterisk_tmpfs_t
240
241 - Set files with the asterisk_tmpfs_t type, if you want to store aster‐
242 isk files on a tmpfs file system.
243
244
245
246 asterisk_var_lib_t
247
248 - Set files with the asterisk_var_lib_t type, if you want to store the
249 asterisk files under the /var/lib directory.
250
251
252
253 asterisk_var_run_t
254
255 - Set files with the asterisk_var_run_t type, if you want to store the
256 asterisk files under the /run or /var/run directory.
257
258
259
260 Note: File context can be temporarily modified with the chcon command.
261 If you want to permanently change the file context you need to use the
262 semanage fcontext command. This will modify the SELinux labeling data‐
263 base. You will need to use restorecon to apply the labels.
264
265
267 semanage fcontext can also be used to manipulate default file context
268 mappings.
269
270 semanage permissive can also be used to manipulate whether or not a
271 process type is permissive.
272
273 semanage module can also be used to enable/disable/install/remove pol‐
274 icy modules.
275
276 semanage port can also be used to manipulate the port definitions
277
278 semanage boolean can also be used to manipulate the booleans
279
280
281 system-config-selinux is a GUI tool available to customize SELinux pol‐
282 icy settings.
