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

234 SELinux requires files to have an extended attribute to define the file
235 type.
236
237 You can see the context of a file using the -Z option to ls
238
239 Policy governs the access confined processes have to these files.
240 SELinux tvtime policy is very flexible allowing users to setup their
241 tvtime processes in as secure a method as possible.
242
243 STANDARD FILE CONTEXT
244
245 SELinux defines the file context types for the tvtime, if you wanted to
246 store files with these types in a diffent paths, you need to execute
247 the semanage command to sepecify alternate labeling and then use
248 restorecon to put the labels on disk.
249
250 semanage fcontext -a -t tvtime_tmpfs_t '/srv/mytvtime_content(/.*)?'
251 restorecon -R -v /srv/mytvtime_content
252
253 Note: SELinux often uses regular expressions to specify labels that
254 match multiple files.
255
256 The following file types are defined for tvtime:
257
258
259
260 tvtime_exec_t
261
262 - Set files with the tvtime_exec_t type, if you want to transition an
263 executable to the tvtime_t domain.
264
265
266
267 tvtime_home_t
268
269 - Set files with the tvtime_home_t type, if you want to store tvtime
270 files in the users home directory.
271
272
273
274 tvtime_tmp_t
275
276 - Set files with the tvtime_tmp_t type, if you want to store tvtime
277 temporary files in the /tmp directories.
278
279
280
281 tvtime_tmpfs_t
282
283 - Set files with the tvtime_tmpfs_t type, if you want to store tvtime
284 files on a tmpfs file system.
285
286
287
288 Note: File context can be temporarily modified with the chcon command.
289 If you want to permanently change the file context you need to use the
290 semanage fcontext command. This will modify the SELinux labeling data‐
291 base. You will need to use restorecon to apply the labels.
292
293
295 semanage fcontext can also be used to manipulate default file context
296 mappings.
297
298 semanage permissive can also be used to manipulate whether or not a
299 process type is permissive.
300
301 semanage module can also be used to enable/disable/install/remove pol‐
302 icy modules.
303
304 semanage boolean can also be used to manipulate the booleans
305
306
307 system-config-selinux is a GUI tool available to customize SELinux pol‐
308 icy settings.
