6 mongod_selinux - Security Enhanced Linux Policy for the mongod pro‐
7 cesses
8
10 Security-Enhanced Linux secures the mongod processes via flexible
11 mandatory access control.
12
13 The mongod processes execute with the mongod_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 mongod_t
20
21
22
24 The mongod_t SELinux type can be entered via the file_type, unla‐
25 beled_t, proc_type, filesystem_type, mtrr_device_t, sysctl_type, mon‐
26 god_exec_t file types.
27
28 The default entrypoint paths for the mongod_t domain are the following:
29
30 all files on the system, /dev/cpu/mtrr, /usr/bin/mongod, /usr/bin/mon‐
31 gos, /usr/share/aeolus-conductor/dbomatic/dbomatic
32
34 SELinux defines process types (domains) for each process running on the
35 system
36
37 You can see the context of a process using the -Z option to ps
38
39 Policy governs the access confined processes have to files. SELinux
40 mongod policy is very flexible allowing users to setup their mongod
41 processes in as secure a method as possible.
42
43 The following process types are defined for mongod:
44
45 mongod_t
46
47 Note: semanage permissive -a mongod_t can be used to make the process
48 type mongod_t permissive. SELinux does not deny access to permissive
49 process types, but the AVC (SELinux denials) messages are still gener‐
50 ated.
51
52
54 SELinux policy is customizable based on least access required. mongod
55 policy is extremely flexible and has several booleans that allow you to
56 manipulate the policy and run mongod with the tightest access possible.

89 If you want to allow unconfined executables to make their heap memory
90 executable. Doing this is a really bad idea. Probably indicates a
91 badly coded executable, but could indicate an attack. This executable
92 should be reported in bugzilla, you must turn on the allow_execheap
93 boolean. Disabled by default.

95 setsebool -P allow_execheap 1
96
97

102 boolean. Enabled by default.
103

164
165 setsebool -P init_upstart 1
166
167
168
169 If you want to allow certain domains to map low memory in the kernel,
170 you must turn on the mmap_low_allowed boolean. Disabled by default.
171

191
193 SELinux defines port types to represent TCP and UDP ports.
194
195 You can see the types associated with a port by using the following
196 command:
197
198 semanage port -l
199
200
201 Policy governs the access confined processes have to these ports.
202 SELinux mongod policy is very flexible allowing users to setup their
203 mongod processes in as secure a method as possible.
204
205 The following port types are defined for mongod:
206
207
208 mongod_port_t
209
210
211
212 Default Defined Ports:
213 tcp 27017-27019,28017-28019
214
216 The SELinux process type mongod_t can manage files labeled with the
217 following file types. The paths listed are the default paths for these
218 file types. Note the processes UID still need to have DAC permissions.
219
220 file_type
221
222 all files on the system
223
224
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 mongod policy is very flexible allowing users to setup their
233 mongod processes in as secure a method as possible.
234
235 STANDARD FILE CONTEXT
236
237 SELinux defines the file context types for the mongod, if you wanted to
238 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 mongod_var_run_t '/srv/mymongod_content(/.*)?'
243 restorecon -R -v /srv/mymongod_content
244
245 Note: SELinux often uses regular expressions to specify labels that
246 match multiple files.
247
248 The following file types are defined for mongod:
249
250
251
252 mongod_exec_t
253
254 - Set files with the mongod_exec_t type, if you want to transition an
255 executable to the mongod_t domain.
256
257
258 Paths:
259 /usr/bin/mongod, /usr/bin/mongos, /usr/share/aeolus-conductor/dbo‐
260 matic/dbomatic
261
262
263 mongod_initrc_exec_t
264
265 - Set files with the mongod_initrc_exec_t type, if you want to transi‐
266 tion an executable to the mongod_initrc_t domain.
267
268
269 Paths:
270 /etc/rc.d/init.d/mongod, /etc/rc.d/init.d/mongos
271
272
273 mongod_log_t
274
275 - Set files with the mongod_log_t type, if you want to treat the data
276 as mongod log data, usually stored under the /var/log directory.
277
278
279
280 mongod_tmp_t
281
282 - Set files with the mongod_tmp_t type, if you want to store mongod
283 temporary files in the /tmp directories.
284
285
286
287 mongod_var_lib_t
288
289 - Set files with the mongod_var_lib_t type, if you want to store the
290 mongod files under the /var/lib directory.
291
292
293
294 mongod_var_run_t
295
296 - Set files with the mongod_var_run_t type, if you want to store the
297 mongod files under the /run or /var/run directory.
298
299
300 Paths:
301 /var/run/mongodb(/.*)?, /var/run/aeolus/dbomatic.pid
302
303
304 Note: File context can be temporarily modified with the chcon command.
305 If you want to permanently change the file context you need to use the
306 semanage fcontext command. This will modify the SELinux labeling data‐
307 base. You will need to use restorecon to apply the labels.
308
309
311 semanage fcontext can also be used to manipulate default file context
312 mappings.
313
314 semanage permissive can also be used to manipulate whether or not a
315 process type is permissive.
316
317 semanage module can also be used to enable/disable/install/remove pol‐
318 icy modules.
319
320 semanage port can also be used to manipulate the port definitions
321
322 semanage boolean can also be used to manipulate the booleans
323
324
325 system-config-selinux is a GUI tool available to customize SELinux pol‐
326 icy settings.
