6 rhgb_selinux - Security Enhanced Linux Policy for the rhgb processes
7
9 Security-Enhanced Linux secures the rhgb processes via flexible manda‐
10 tory access control.
11
12 The rhgb processes execute with the rhgb_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 rhgb_t
19
20
21
23 The rhgb_t SELinux type can be entered via the rhgb_exec_t file type.
24
25 The default entrypoint paths for the rhgb_t domain are the following:
26
27 /usr/bin/rhgb
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 rhgb policy is very flexible allowing users to setup their rhgb pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for rhgb:
40
41 rhgb_t
42
43 Note: semanage permissive -a rhgb_t can be used to make the process
44 type rhgb_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. rhgb
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run rhgb with the tightest access possible.

122 on the global_ssp boolean. Disabled by default.
123
124 setsebool -P global_ssp 1
125
126
127
128 If you want to enable support for upstart as the init program, you must
129 turn on the init_upstart boolean. Enabled by default.
130
131 setsebool -P init_upstart 1
132
133
134
136 The SELinux process type rhgb_t can manage files labeled with the fol‐
137 lowing file types. The paths listed are the default paths for these
138 file types. Note the processes UID still need to have DAC permissions.

205 SELinux requires files to have an extended attribute to define the file
206 type.
207
208 You can see the context of a file using the -Z option to ls
209
210 Policy governs the access confined processes have to these files.
211 SELinux rhgb policy is very flexible allowing users to setup their rhgb
212 processes in as secure a method as possible.
213
214 STANDARD FILE CONTEXT
215
216 SELinux defines the file context types for the rhgb, if you wanted to
217 store files with these types in a diffent paths, you need to execute
218 the semanage command to sepecify alternate labeling and then use
219 restorecon to put the labels on disk.
220
221 semanage fcontext -a -t rhgb_tmpfs_t '/srv/myrhgb_content(/.*)?'
222 restorecon -R -v /srv/myrhgb_content
223
224 Note: SELinux often uses regular expressions to specify labels that
225 match multiple files.
226
227 The following file types are defined for rhgb:
228
229
230
231 rhgb_exec_t
232
233 - Set files with the rhgb_exec_t type, if you want to transition an
234 executable to the rhgb_t domain.
235
236
237
238 rhgb_tmpfs_t
239
240 - Set files with the rhgb_tmpfs_t type, if you want to store rhgb files
241 on a tmpfs file system.
242
243
244
245 Note: File context can be temporarily modified with the chcon command.
246 If you want to permanently change the file context you need to use the
247 semanage fcontext command. This will modify the SELinux labeling data‐
248 base. You will need to use restorecon to apply the labels.
249
250
252 semanage fcontext can also be used to manipulate default file context
253 mappings.
254
255 semanage permissive can also be used to manipulate whether or not a
256 process type is permissive.
257
258 semanage module can also be used to enable/disable/install/remove pol‐
259 icy modules.
260
261 semanage boolean can also be used to manipulate the booleans
262
263
264 system-config-selinux is a GUI tool available to customize SELinux pol‐
265 icy settings.
