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 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 For example:
18 ps -eZ | grep asterisk_t
20
24 The asterisk_t SELinux type can be entered via the asterisk_exec_t file
25 type.
26 The default entrypoint paths for the asterisk_t domain are the follow‐
28 ing:
29 /usr/sbin/asterisk
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for asterisk:
43 asterisk_t
45 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
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 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63 setsebool -P authlogin_nsswitch_use_ldap 1
65 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70 setsebool -P fips_mode 1
72 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Disabled by default.
77 setsebool -P kerberos_enabled 1
79 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84 setsebool -P nis_enabled 1
86 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Disabled by default.
91 setsebool -P nscd_use_shm 1
93
97 SELinux defines port types to represent TCP and UDP ports.
98 You can see the types associated with a port by using the following
100 command:
101 semanage port -l
103 Policy governs the access confined processes have to these ports.
106 SELinux asterisk policy is very flexible allowing users to setup their
107 asterisk processes in as secure a method as possible.
108 The following port types are defined for asterisk:
110 asterisk_port_t
113 Default Defined Ports:
117 tcp 1720
118 udp 2427,2727,4569
119
121 The SELinux process type asterisk_t can manage files labeled with the
122 following file types. The paths listed are the default paths for these
123 file types. Note the processes UID still need to have DAC permissions.
124 asterisk_log_t
126 /var/log/asterisk(/.*)?
128 asterisk_spool_t
130 /var/spool/asterisk(/.*)?
132 asterisk_tmp_t

184 SELinux requires files to have an extended attribute to define the file
185 type.
186 You can see the context of a file using the -Z option to ls
188 Policy governs the access confined processes have to these files.
190 SELinux asterisk policy is very flexible allowing users to setup their
191 asterisk processes in as secure a method as possible.
192 STANDARD FILE CONTEXT
194 SELinux defines the file context types for the asterisk, if you wanted
196 to store files with these types in a diffent paths, you need to execute
197 the semanage command to sepecify alternate labeling and then use
198 restorecon to put the labels on disk.
199 semanage fcontext -a -t asterisk_var_run_t '/srv/myasterisk_con‐
201 tent(/.*)?'
202 restorecon -R -v /srv/myasterisk_content
203 Note: SELinux often uses regular expressions to specify labels that
205 match multiple files.
206 The following file types are defined for asterisk:
208 asterisk_etc_t
212 - Set files with the asterisk_etc_t type, if you want to store asterisk
214 files in the /etc directories.
215 asterisk_exec_t
219 - Set files with the asterisk_exec_t type, if you want to transition an
221 executable to the asterisk_t domain.
222 asterisk_initrc_exec_t
226 - Set files with the asterisk_initrc_exec_t type, if you want to tran‐
228 sition an executable to the asterisk_initrc_t domain.
229 asterisk_log_t
233 - Set files with the asterisk_log_t type, if you want to treat the data
235 as asterisk log data, usually stored under the /var/log directory.
236 asterisk_spool_t
240 - Set files with the asterisk_spool_t type, if you want to store the
242 asterisk files under the /var/spool directory.
243 asterisk_tmp_t
247 - Set files with the asterisk_tmp_t type, if you want to store asterisk
249 temporary files in the /tmp directories.
250 asterisk_tmpfs_t
254 - Set files with the asterisk_tmpfs_t type, if you want to store aster‐
256 isk files on a tmpfs file system.
257 asterisk_var_lib_t
261 - Set files with the asterisk_var_lib_t type, if you want to store the
263 asterisk files under the /var/lib directory.
264 asterisk_var_run_t
268 - Set files with the asterisk_var_run_t type, if you want to store the
270 asterisk files under the /run or /var/run directory.
271 Note: File context can be temporarily modified with the chcon command.
275 If you want to permanently change the file context you need to use the
276 semanage fcontext command. This will modify the SELinux labeling data‐
277 base. You will need to use restorecon to apply the labels.
278
281 semanage fcontext can also be used to manipulate default file context
282 mappings.
283 semanage permissive can also be used to manipulate whether or not a
285 process type is permissive.
286 semanage module can also be used to enable/disable/install/remove pol‐
288 icy modules.
289 semanage port can also be used to manipulate the port definitions
291 semanage boolean can also be used to manipulate the booleans
293 system-config-selinux is a GUI tool available to customize SELinux pol‐
296 icy settings.
