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. Disabled 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.

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