6 saslauthd_selinux - Security Enhanced Linux Policy for the saslauthd
7 processes
8
10 Security-Enhanced Linux secures the saslauthd processes via flexible
11 mandatory access control.
12
13 The saslauthd processes execute with the saslauthd_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 saslauthd_t
20
21
22
24 The saslauthd_t SELinux type can be entered via the saslauthd_exec_t
25 file type.
26
27 The default entrypoint paths for the saslauthd_t domain are the follow‐
28 ing:
29
30 /usr/sbin/saslauthd
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 saslauthd policy is very flexible allowing users to setup their saslau‐
40 thd processes in as secure a method as possible.
41
42 The following process types are defined for saslauthd:
43
44 saslauthd_t
45
46 Note: semanage permissive -a saslauthd_t can be used to make the
47 process type saslauthd_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required. saslau‐
54 thd policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run saslauthd with the tightest access
56 possible.

252 SELinux requires files to have an extended attribute to define the file
253 type.
254
255 You can see the context of a file using the -Z option to ls
256
257 Policy governs the access confined processes have to these files.
258 SELinux saslauthd policy is very flexible allowing users to setup their
259 saslauthd processes in as secure a method as possible.
260
261 STANDARD FILE CONTEXT
262
263 SELinux defines the file context types for the saslauthd, if you wanted
264 to store files with these types in a diffent paths, you need to execute
265 the semanage command to sepecify alternate labeling and then use
266 restorecon to put the labels on disk.
267
268 semanage fcontext -a -t saslauthd_var_run_t '/srv/mysaslauthd_con‐
269 tent(/.*)?'
270 restorecon -R -v /srv/mysaslauthd_content
271
272 Note: SELinux often uses regular expressions to specify labels that
273 match multiple files.
274
275 The following file types are defined for saslauthd:
276
277
278
279 saslauthd_exec_t
280
281 - Set files with the saslauthd_exec_t type, if you want to transition
282 an executable to the saslauthd_t domain.
283
284
285
286 saslauthd_initrc_exec_t
287
288 - Set files with the saslauthd_initrc_exec_t type, if you want to tran‐
289 sition an executable to the saslauthd_initrc_t domain.
290
291
292
293 saslauthd_keytab_t
294
295 - Set files with the saslauthd_keytab_t type, if you want to treat the
296 files as kerberos keytab files.
297
298
299
300 saslauthd_var_run_t
301
302 - Set files with the saslauthd_var_run_t type, if you want to store the
303 saslauthd files under the /run or /var/run directory.
304
305
306 Paths:
307 /var/lib/sasl2(/.*)?, /var/run/saslauthd(/.*)?
308
309
310 Note: File context can be temporarily modified with the chcon command.
311 If you want to permanently change the file context you need to use the
312 semanage fcontext command. This will modify the SELinux labeling data‐
313 base. You will need to use restorecon to apply the labels.
314
315
317 semanage fcontext can also be used to manipulate default file context
318 mappings.
319
320 semanage permissive can also be used to manipulate whether or not a
321 process type is permissive.
322
323 semanage module can also be used to enable/disable/install/remove pol‐
324 icy modules.
325
326 semanage boolean can also be used to manipulate the booleans
327
328
329 system-config-selinux is a GUI tool available to customize SELinux pol‐
330 icy settings.
