6 nut_upsmon_selinux - Security Enhanced Linux Policy for the nut_upsmon
7 processes
8
10 Security-Enhanced Linux secures the nut_upsmon processes via flexible
11 mandatory access control.
12
13 The nut_upsmon processes execute with the nut_upsmon_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep nut_upsmon_t
20
21
22
24 The nut_upsmon_t SELinux type can be entered via the nut_upsmon_exec_t
25 file type.
26
27 The default entrypoint paths for the nut_upsmon_t domain are the fol‐
28 lowing:
29
30 /usr/sbin/upsmon
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 nut_upsmon policy is very flexible allowing users to setup their
40 nut_upsmon processes in as secure a method as possible.
41
42 The following process types are defined for nut_upsmon:
43
44 nut_upsmon_t
45
46 Note: semanage permissive -a nut_upsmon_t can be used to make the
47 process type nut_upsmon_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.
54 nut_upsmon policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run nut_upsmon with the tightest
56 access possible.

171 The SELinux process type nut_upsmon_t can manage files labeled with the
172 following file types. The paths listed are the default paths for these
173 file types. Note the processes UID still need to have DAC permissions.

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