6 iodined_selinux - Security Enhanced Linux Policy for the iodined pro‐
7 cesses
8
10 Security-Enhanced Linux secures the iodined processes via flexible
11 mandatory access control.
12
13 The iodined processes execute with the iodined_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep iodined_t
20
21
22
24 The iodined_t SELinux type can be entered via the iodined_exec_t file
25 type.
26
27 The default entrypoint paths for the iodined_t domain are the follow‐
28 ing:
29
30 /usr/sbin/iodined
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 iodined policy is very flexible allowing users to setup their iodined
40 processes in as secure a method as possible.
41
42 The following process types are defined for iodined:
43
44 iodined_t
45
46 Note: semanage permissive -a iodined_t can be used to make the process
47 type iodined_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
51
53 SELinux policy is customizable based on least access required. iodined
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run iodined with the tightest access possi‐
56 ble.

59
60 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63
64 setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70
71 setsebool -P fips_mode 1
72
73
74
75 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Enabled by default.
77
78 setsebool -P kerberos_enabled 1
79
80
81
82 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84
85 setsebool -P nis_enabled 1
86
87
88
89 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Disabled by default.
91
92 setsebool -P nscd_use_shm 1
93
94
95
97 The SELinux process type iodined_t can manage files labeled with the
98 following file types. The paths listed are the default paths for these
99 file types. Note the processes UID still need to have DAC permissions.

138 SELinux requires files to have an extended attribute to define the file
139 type.
140
141 You can see the context of a file using the -Z option to ls
142
143 Policy governs the access confined processes have to these files.
144 SELinux iodined policy is very flexible allowing users to setup their
145 iodined processes in as secure a method as possible.
146
147 STANDARD FILE CONTEXT
148
149 SELinux defines the file context types for the iodined, if you wanted
150 to store files with these types in a diffent paths, you need to execute
151 the semanage command to sepecify alternate labeling and then use
152 restorecon to put the labels on disk.
153
154 semanage fcontext -a -t iodined_unit_file_t '/srv/myiodined_con‐
155 tent(/.*)?'
156 restorecon -R -v /srv/myiodined_content
157
158 Note: SELinux often uses regular expressions to specify labels that
159 match multiple files.
160
161 The following file types are defined for iodined:
162
163
164
165 iodined_exec_t
166
167 - Set files with the iodined_exec_t type, if you want to transition an
168 executable to the iodined_t domain.
169
170
171
172 iodined_initrc_exec_t
173
174 - Set files with the iodined_initrc_exec_t type, if you want to transi‐
175 tion an executable to the iodined_initrc_t domain.
176
177
178
179 iodined_unit_file_t
180
181 - Set files with the iodined_unit_file_t type, if you want to treat the
182 files as iodined unit content.
183
184
185
186 Note: File context can be temporarily modified with the chcon command.
187 If you want to permanently change the file context you need to use the
188 semanage fcontext command. This will modify the SELinux labeling data‐
189 base. You will need to use restorecon to apply the labels.
190
191
193 semanage fcontext can also be used to manipulate default file context
194 mappings.
195
196 semanage permissive can also be used to manipulate whether or not a
197 process type is permissive.
198
199 semanage module can also be used to enable/disable/install/remove pol‐
200 icy modules.
201
202 semanage boolean can also be used to manipulate the booleans
203
204
205 system-config-selinux is a GUI tool available to customize SELinux pol‐
206 icy settings.
