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.
53
54
55
56 If you want to allow all domains to execute in fips_mode, you must turn
57 on the fips_mode boolean. Enabled by default.
58
59 setsebool -P fips_mode 1
60
61
62
63 If you want to allow system to run with NIS, you must turn on the
64 nis_enabled boolean. Disabled by default.
65
66 setsebool -P nis_enabled 1
67
68
69
70 If you want to allow confined applications to use nscd shared memory,
71 you must turn on the nscd_use_shm boolean. Enabled by default.
72
73 setsebool -P nscd_use_shm 1
74
75
76
78 The SELinux process type rhgb_t can manage files labeled with the fol‐
79 lowing file types. The paths listed are the default paths for these
80 file types. Note the processes UID still need to have DAC permissions.

126 SELinux requires files to have an extended attribute to define the file
127 type.
128
129 You can see the context of a file using the -Z option to ls
130
131 Policy governs the access confined processes have to these files.
132 SELinux rhgb policy is very flexible allowing users to setup their rhgb
133 processes in as secure a method as possible.
134
135 STANDARD FILE CONTEXT
136
137 SELinux defines the file context types for the rhgb, if you wanted to
138 store files with these types in a diffent paths, you need to execute
139 the semanage command to specify alternate labeling and then use re‐
140 storecon to put the labels on disk.
141
142 semanage fcontext -a -t rhgb_tmpfs_t '/srv/myrhgb_content(/.*)?'
143 restorecon -R -v /srv/myrhgb_content
144
145 Note: SELinux often uses regular expressions to specify labels that
146 match multiple files.
147
148 The following file types are defined for rhgb:
149
150
151
152 rhgb_exec_t
153
154 - Set files with the rhgb_exec_t type, if you want to transition an ex‐
155 ecutable to the rhgb_t domain.
156
157
158
159 rhgb_tmpfs_t
160
161 - Set files with the rhgb_tmpfs_t type, if you want to store rhgb files
162 on a tmpfs file system.
163
164
165
166 Note: File context can be temporarily modified with the chcon command.
167 If you want to permanently change the file context you need to use the
168 semanage fcontext command. This will modify the SELinux labeling data‐
169 base. You will need to use restorecon to apply the labels.
170
171
173 semanage fcontext can also be used to manipulate default file context
174 mappings.
175
176 semanage permissive can also be used to manipulate whether or not a
177 process type is permissive.
178
179 semanage module can also be used to enable/disable/install/remove pol‐
180 icy modules.
181
182 semanage boolean can also be used to manipulate the booleans
183
184
185 system-config-selinux is a GUI tool available to customize SELinux pol‐
186 icy settings.
