6 useradd_selinux - Security Enhanced Linux Policy for the useradd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the useradd processes via flexible
11 mandatory access control.
12
13 The useradd processes execute with the useradd_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 useradd_t
20
21
22
24 The useradd_t SELinux type can be entered via the user_home_t, user‐
25 add_exec_t file types.
26
27 The default entrypoint paths for the useradd_t domain are the follow‐
28 ing:
29
30 /home/[^/]+/.+, /usr/sbin/useradd, /usr/sbin/userdel, /usr/sbin/user‐
31 mod, /usr/sbin/newusers
32
34 SELinux defines process types (domains) for each process running on the
35 system
36
37 You can see the context of a process using the -Z option to ps
38
39 Policy governs the access confined processes have to files. SELinux
40 useradd policy is very flexible allowing users to setup their useradd
41 processes in as secure a method as possible.
42
43 The following process types are defined for useradd:
44
45 useradd_t
46
47 Note: semanage permissive -a useradd_t can be used to make the process
48 type useradd_t permissive. SELinux does not deny access to permissive
49 process types, but the AVC (SELinux denials) messages are still gener‐
50 ated.
51
52
54 SELinux policy is customizable based on least access required. useradd
55 policy is extremely flexible and has several booleans that allow you to
56 manipulate the policy and run useradd with the tightest access possi‐
57 ble.
58
59
60
61 If you want to allow all domains to execute in fips_mode, you must turn
62 on the fips_mode boolean. Enabled by default.
63
64 setsebool -P fips_mode 1
65
66
67
68 If you want to allow system to run with NIS, you must turn on the
69 nis_enabled boolean. Disabled by default.
70
71 setsebool -P nis_enabled 1
72
73
74
75 If you want to allow samba to act as the domain controller, add users,
76 groups and change passwords, you must turn on the samba_domain_con‐
77 troller boolean. Disabled by default.
78
79 setsebool -P samba_domain_controller 1
80
81
82
83 If you want to support NFS home directories, you must turn on the
84 use_nfs_home_dirs boolean. Disabled by default.
85
86 setsebool -P use_nfs_home_dirs 1
87
88
89
90 If you want to support SAMBA home directories, you must turn on the
91 use_samba_home_dirs boolean. Disabled by default.
92
93 setsebool -P use_samba_home_dirs 1
94
95
96
98 The SELinux process type useradd_t can manage files labeled with the
99 following file types. The paths listed are the default paths for these
100 file types. Note the processes UID still need to have DAC permissions.

219 SELinux requires files to have an extended attribute to define the file
220 type.
221
222 You can see the context of a file using the -Z option to ls
223
224 Policy governs the access confined processes have to these files.
225 SELinux useradd policy is very flexible allowing users to setup their
226 useradd processes in as secure a method as possible.
227
228 STANDARD FILE CONTEXT
229
230 SELinux defines the file context types for the useradd, if you wanted
231 to store files with these types in a diffent paths, you need to execute
232 the semanage command to specify alternate labeling and then use re‐
233 storecon to put the labels on disk.
234
235 semanage fcontext -a -t useradd_var_run_t '/srv/myuseradd_con‐
236 tent(/.*)?'
237 restorecon -R -v /srv/myuseradd_content
238
239 Note: SELinux often uses regular expressions to specify labels that
240 match multiple files.
241
242 The following file types are defined for useradd:
243
244
245
246 useradd_exec_t
247
248 - Set files with the useradd_exec_t type, if you want to transition an
249 executable to the useradd_t domain.
250
251
252 Paths:
253 /usr/sbin/useradd, /usr/sbin/userdel, /usr/sbin/usermod,
254 /usr/sbin/newusers
255
256
257 useradd_var_run_t
258
259 - Set files with the useradd_var_run_t type, if you want to store the
260 useradd files under the /run or /var/run directory.
261
262
263
264 Note: File context can be temporarily modified with the chcon command.
265 If you want to permanently change the file context you need to use the
266 semanage fcontext command. This will modify the SELinux labeling data‐
267 base. You will need to use restorecon to apply the labels.
268
269
271 semanage fcontext can also be used to manipulate default file context
272 mappings.
273
274 semanage permissive can also be used to manipulate whether or not a
275 process type is permissive.
276
277 semanage module can also be used to enable/disable/install/remove pol‐
278 icy modules.
279
280 semanage boolean can also be used to manipulate the booleans
281
282
283 system-config-selinux is a GUI tool available to customize SELinux pol‐
284 icy settings.
