6 tgtd_selinux - Security Enhanced Linux Policy for the tgtd processes
7
9 Security-Enhanced Linux secures the tgtd processes via flexible manda‐
10 tory access control.
11
12 The tgtd processes execute with the tgtd_t SELinux type. You can check
13 if you have these processes running by executing the ps command with
14 the -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep tgtd_t
19
20
21
23 The tgtd_t SELinux type can be entered via the tgtd_exec_t file type.
24
25 The default entrypoint paths for the tgtd_t domain are the following:
26
27 /usr/sbin/tgtd
28
30 SELinux defines process types (domains) for each process running on the
31 system
32
33 You can see the context of a process using the -Z option to ps
34
35 Policy governs the access confined processes have to files. SELinux
36 tgtd policy is very flexible allowing users to setup their tgtd pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for tgtd:
40
41 tgtd_t
42
43 Note: semanage permissive -a tgtd_t can be used to make the process
44 type tgtd_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
48
50 SELinux policy is customizable based on least access required. tgtd
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run tgtd with the tightest access possible.

131 on the global_ssp boolean. Disabled by default.
132
133 setsebool -P global_ssp 1
134
135
136
138 The SELinux process type tgtd_t can manage files labeled with the fol‐
139 lowing file types. The paths listed are the default paths for these
140 file types. Note the processes UID still need to have DAC permissions.

190 SELinux requires files to have an extended attribute to define the file
191 type.
192
193 You can see the context of a file using the -Z option to ls
194
195 Policy governs the access confined processes have to these files.
196 SELinux tgtd policy is very flexible allowing users to setup their tgtd
197 processes in as secure a method as possible.
198
199 STANDARD FILE CONTEXT
200
201 SELinux defines the file context types for the tgtd, if you wanted to
202 store files with these types in a diffent paths, you need to execute
203 the semanage command to sepecify alternate labeling and then use
204 restorecon to put the labels on disk.
205
206 semanage fcontext -a -t tgtd_var_run_t '/srv/mytgtd_content(/.*)?'
207 restorecon -R -v /srv/mytgtd_content
208
209 Note: SELinux often uses regular expressions to specify labels that
210 match multiple files.
211
212 The following file types are defined for tgtd:
213
214
215
216 tgtd_exec_t
217
218 - Set files with the tgtd_exec_t type, if you want to transition an
219 executable to the tgtd_t domain.
220
221
222
223 tgtd_initrc_exec_t
224
225 - Set files with the tgtd_initrc_exec_t type, if you want to transition
226 an executable to the tgtd_initrc_t domain.
227
228
229
230 tgtd_tmp_t
231
232 - Set files with the tgtd_tmp_t type, if you want to store tgtd tempo‐
233 rary files in the /tmp directories.
234
235
236
237 tgtd_tmpfs_t
238
239 - Set files with the tgtd_tmpfs_t type, if you want to store tgtd files
240 on a tmpfs file system.
241
242
243
244 tgtd_var_lib_t
245
246 - Set files with the tgtd_var_lib_t type, if you want to store the tgtd
247 files under the /var/lib directory.
248
249
250
251 tgtd_var_run_t
252
253 - Set files with the tgtd_var_run_t type, if you want to store the tgtd
254 files under the /run or /var/run directory.
255
256
257
258 Note: File context can be temporarily modified with the chcon command.
259 If you want to permanently change the file context you need to use the
260 semanage fcontext command. This will modify the SELinux labeling data‐
261 base. You will need to use restorecon to apply the labels.
262
263
265 semanage fcontext can also be used to manipulate default file context
266 mappings.
267
268 semanage permissive can also be used to manipulate whether or not a
269 process type is permissive.
270
271 semanage module can also be used to enable/disable/install/remove pol‐
272 icy modules.
273
274 semanage boolean can also be used to manipulate the booleans
275
276
277 system-config-selinux is a GUI tool available to customize SELinux pol‐
278 icy settings.
