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.

123 SELinux requires files to have an extended attribute to define the file
124 type.
125
126 You can see the context of a file using the -Z option to ls
127
128 Policy governs the access confined processes have to these files.
129 SELinux rhgb policy is very flexible allowing users to setup their rhgb
130 processes in as secure a method as possible.
131
132 STANDARD FILE CONTEXT
133
134 SELinux defines the file context types for the rhgb, if you wanted to
135 store files with these types in a diffent paths, you need to execute
136 the semanage command to specify alternate labeling and then use re‐
137 storecon to put the labels on disk.
138
139 semanage fcontext -a -t rhgb_tmpfs_t '/srv/myrhgb_content(/.*)?'
140 restorecon -R -v /srv/myrhgb_content
141
142 Note: SELinux often uses regular expressions to specify labels that
143 match multiple files.
144
145 The following file types are defined for rhgb:
146
147
148
149 rhgb_exec_t
150
151 - Set files with the rhgb_exec_t type, if you want to transition an ex‐
152 ecutable to the rhgb_t domain.
153
154
155
156 rhgb_tmpfs_t
157
158 - Set files with the rhgb_tmpfs_t type, if you want to store rhgb files
159 on a tmpfs file system.
160
161
162
163 Note: File context can be temporarily modified with the chcon command.
164 If you want to permanently change the file context you need to use the
165 semanage fcontext command. This will modify the SELinux labeling data‐
166 base. You will need to use restorecon to apply the labels.
167
168
170 semanage fcontext can also be used to manipulate default file context
171 mappings.
172
173 semanage permissive can also be used to manipulate whether or not a
174 process type is permissive.
175
176 semanage module can also be used to enable/disable/install/remove pol‐
177 icy modules.
178
179 semanage boolean can also be used to manipulate the booleans
180
181
182 system-config-selinux is a GUI tool available to customize SELinux pol‐
183 icy settings.
