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.

152 SELinux requires files to have an extended attribute to define the file
153 type.
154
155 You can see the context of a file using the -Z option to ls
156
157 Policy governs the access confined processes have to these files.
158 SELinux asterisk policy is very flexible allowing users to setup their
159 asterisk processes in as secure a method as possible.
160
161 STANDARD FILE CONTEXT
162
163 SELinux defines the file context types for the asterisk, if you wanted
164 to store files with these types in a diffent paths, you need to execute
165 the semanage command to sepecify alternate labeling and then use
166 restorecon to put the labels on disk.
167
168 semanage fcontext -a -t asterisk_var_run_t '/srv/myasterisk_con‐
169 tent(/.*)?'
170 restorecon -R -v /srv/myasterisk_content
171
172 Note: SELinux often uses regular expressions to specify labels that
173 match multiple files.
174
175 The following file types are defined for asterisk:
176
177
178
179 asterisk_etc_t
180
181 - Set files with the asterisk_etc_t type, if you want to store asterisk
182 files in the /etc directories.
183
184
185
186 asterisk_exec_t
187
188 - Set files with the asterisk_exec_t type, if you want to transition an
189 executable to the asterisk_t domain.
190
191
192
193 asterisk_initrc_exec_t
194
195 - Set files with the asterisk_initrc_exec_t type, if you want to tran‐
196 sition an executable to the asterisk_initrc_t domain.
197
198
199
200 asterisk_log_t
201
202 - Set files with the asterisk_log_t type, if you want to treat the data
203 as asterisk log data, usually stored under the /var/log directory.
204
205
206
207 asterisk_spool_t
208
209 - Set files with the asterisk_spool_t type, if you want to store the
210 asterisk files under the /var/spool directory.
211
212
213
214 asterisk_tmp_t
215
216 - Set files with the asterisk_tmp_t type, if you want to store asterisk
217 temporary files in the /tmp directories.
218
219
220
221 asterisk_tmpfs_t
222
223 - Set files with the asterisk_tmpfs_t type, if you want to store aster‐
224 isk files on a tmpfs file system.
225
226
227
228 asterisk_var_lib_t
229
230 - Set files with the asterisk_var_lib_t type, if you want to store the
231 asterisk files under the /var/lib directory.
232
233
234
235 asterisk_var_run_t
236
237 - Set files with the asterisk_var_run_t type, if you want to store the
238 asterisk files under the /run or /var/run directory.
239
240
241
242 Note: File context can be temporarily modified with the chcon command.
243 If you want to permanently change the file context you need to use the
244 semanage fcontext command. This will modify the SELinux labeling data‐
245 base. You will need to use restorecon to apply the labels.
246
247
249 semanage fcontext can also be used to manipulate default file context
250 mappings.
251
252 semanage permissive can also be used to manipulate whether or not a
253 process type is permissive.
254
255 semanage module can also be used to enable/disable/install/remove pol‐
256 icy modules.
257
258 semanage port can also be used to manipulate the port definitions
259
260 semanage boolean can also be used to manipulate the booleans
261
262
263 system-config-selinux is a GUI tool available to customize SELinux pol‐
264 icy settings.
