6 radiusd_selinux - Security Enhanced Linux Policy for the radiusd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the radiusd processes via flexible
11 mandatory access control.
12
13 The radiusd processes execute with the radiusd_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 radiusd_t
20
21
22
24 The radiusd_t SELinux type can be entered via the radiusd_exec_t file
25 type.
26
27 The default entrypoint paths for the radiusd_t domain are the follow‐
28 ing:
29
30 /etc/cron.(daily|monthly)/radiusd,
31 /etc/cron.((daily)|(weekly)|(monthly))/freeradius, /usr/sbin/radiusd,
32 /usr/sbin/freeradius
33
35 SELinux defines process types (domains) for each process running on the
36 system
37
38 You can see the context of a process using the -Z option to ps
39
40 Policy governs the access confined processes have to files. SELinux
41 radiusd policy is very flexible allowing users to setup their radiusd
42 processes in as secure a method as possible.
43
44 The following process types are defined for radiusd:
45
46 radiusd_t
47
48 Note: semanage permissive -a radiusd_t can be used to make the process
49 type radiusd_t permissive. SELinux does not deny access to permissive
50 process types, but the AVC (SELinux denials) messages are still gener‐
51 ated.
52
53
55 SELinux policy is customizable based on least access required. radiusd
56 policy is extremely flexible and has several booleans that allow you to
57 manipulate the policy and run radiusd with the tightest access possi‐
58 ble.

180 SELinux defines port types to represent TCP and UDP ports.
181
182 You can see the types associated with a port by using the following
183 command:
184
185 semanage port -l
186
187
188 Policy governs the access confined processes have to these ports.
189 SELinux radiusd policy is very flexible allowing users to setup their
190 radiusd processes in as secure a method as possible.
191
192 The following port types are defined for radiusd:
193
194
195 radius_port_t
196
197
198
199 Default Defined Ports:
200 tcp 1645,1812,18120-18121
201 udp 1645,1812,18120-18121
202
204 The SELinux process type radiusd_t can manage files labeled with the
205 following file types. The paths listed are the default paths for these
206 file types. Note the processes UID still need to have DAC permissions.

292 SELinux requires files to have an extended attribute to define the file
293 type.
294
295 You can see the context of a file using the -Z option to ls
296
297 Policy governs the access confined processes have to these files.
298 SELinux radiusd policy is very flexible allowing users to setup their
299 radiusd processes in as secure a method as possible.
300
301 EQUIVALENCE DIRECTORIES
302
303
304 radiusd policy stores data with multiple different file context types
305 under the /var/run/radiusd directory. If you would like to store the
306 data in a different directory you can use the semanage command to cre‐
307 ate an equivalence mapping. If you wanted to store this data under the
308 /srv dirctory you would execute the following command:
309
310 semanage fcontext -a -e /var/run/radiusd /srv/radiusd
311 restorecon -R -v /srv/radiusd
312
313 radiusd policy stores data with multiple different file context types
314 under the /var/log/radius directory. If you would like to store the
315 data in a different directory you can use the semanage command to cre‐
316 ate an equivalence mapping. If you wanted to store this data under the
317 /srv dirctory you would execute the following command:
318
319 semanage fcontext -a -e /var/log/radius /srv/radius
320 restorecon -R -v /srv/radius
321
322 STANDARD FILE CONTEXT
323
324 SELinux defines the file context types for the radiusd, if you wanted
325 to store files with these types in a diffent paths, you need to execute
326 the semanage command to sepecify alternate labeling and then use
327 restorecon to put the labels on disk.
328
329 semanage fcontext -a -t radiusd_var_run_t '/srv/myradiusd_con‐
330 tent(/.*)?'
331 restorecon -R -v /srv/myradiusd_content
332
333 Note: SELinux often uses regular expressions to specify labels that
334 match multiple files.
335
336 The following file types are defined for radiusd:
337
338
339
340 radiusd_etc_rw_t
341
342 - Set files with the radiusd_etc_rw_t type, if you want to treat the
343 files as radiusd etc read/write content.
344
345
346
347 radiusd_etc_t
348
349 - Set files with the radiusd_etc_t type, if you want to store radiusd
350 files in the /etc directories.
351
352
353
354 radiusd_exec_t
355
356 - Set files with the radiusd_exec_t type, if you want to transition an
357 executable to the radiusd_t domain.
358
359
360 Paths:
361 /etc/cron.(daily|monthly)/radiusd,
362 /etc/cron.((daily)|(weekly)|(monthly))/freeradius,
363 /usr/sbin/radiusd, /usr/sbin/freeradius
364
365
366 radiusd_initrc_exec_t
367
368 - Set files with the radiusd_initrc_exec_t type, if you want to transi‐
369 tion an executable to the radiusd_initrc_t domain.
370
371
372
373 radiusd_log_t
374
375 - Set files with the radiusd_log_t type, if you want to treat the data
376 as radiusd log data, usually stored under the /var/log directory.
377
378
379 Paths:
380 /var/log/radius(/.*)?, /var/log/radutmp.*, /var/log/radwtmp.*,
381 /var/log/radacct(/.*)?, /var/log/radius.log.*, /var/log/freera‐
382 dius(/.*)?, /var/log/radiusd-freeradius(/.*)?
383
384
385 radiusd_unit_file_t
386
387 - Set files with the radiusd_unit_file_t type, if you want to treat the
388 files as radiusd unit content.
389
390
391
392 radiusd_var_lib_t
393
394 - Set files with the radiusd_var_lib_t type, if you want to store the
395 radiusd files under the /var/lib directory.
396
397
398
399 radiusd_var_run_t
400
401 - Set files with the radiusd_var_run_t type, if you want to store the
402 radiusd files under the /run or /var/run directory.
403
404
405 Paths:
406 /var/run/radiusd(/.*)?, /var/run/radiusd.pid
407
408
409 Note: File context can be temporarily modified with the chcon command.
410 If you want to permanently change the file context you need to use the
411 semanage fcontext command. This will modify the SELinux labeling data‐
412 base. You will need to use restorecon to apply the labels.
413
414
416 semanage fcontext can also be used to manipulate default file context
417 mappings.
418
419 semanage permissive can also be used to manipulate whether or not a
420 process type is permissive.
421
422 semanage module can also be used to enable/disable/install/remove pol‐
423 icy modules.
424
425 semanage port can also be used to manipulate the port definitions
426
427 semanage boolean can also be used to manipulate the booleans
428
429
430 system-config-selinux is a GUI tool available to customize SELinux pol‐
431 icy settings.
