NAME

6       groupadd_selinux - Security Enhanced Linux Policy for the groupadd pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures the  groupadd  processes  via  flexible
11       mandatory access control.
12
13       The  groupadd  processes  execute with the groupadd_t SELinux type. You
14       can check if you have these processes running by executing the ps  com‐
15       mand with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep groupadd_t
20
21
22

ENTRYPOINTS

24       The groupadd_t SELinux type can be entered via the groupadd_exec_t file
25       type.
26
27       The default entrypoint paths for the groupadd_t domain are the  follow‐
28       ing:
29
30       /usr/bin/gpasswd,         /usr/sbin/gpasswd,        /usr/sbin/groupadd,
31       /usr/sbin/groupdel, /usr/sbin/groupmod
32

PROCESS TYPES

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       groupadd policy is very flexible allowing users to setup their groupadd
41       processes in as secure a method as possible.
42
43       The following process types are defined for groupadd:
44
45       groupadd_t
46
47       Note: semanage permissive -a groupadd_t can be used to make the process
48       type groupadd_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

BOOLEANS

54       SELinux  policy  is  customizable  based  on  least  access   required.
55       groupadd  policy  is  extremely  flexible and has several booleans that
56       allow you to manipulate the policy and run groupadd with  the  tightest
57       access possible.

59
60
61       If you want to allow users to resolve user passwd entries directly from
62       ldap rather then using a sssd server, you  must  turn  on  the  authlo‐

MANAGED FILES

159       The SELinux process type groupadd_t can manage files labeled  with  the
160       following file types.  The paths listed are the default paths for these
161       file types.  Note the processes UID still need to have DAC permissions.
162
163       faillog_t
164
165            /var/log/btmp.*
166            /var/log/faillog.*
167            /var/log/tallylog.*
168            /var/run/faillock(/.*)?
169
170       lastlog_t
171
172            /var/log/lastlog.*
173
174       passwd_file_t
175
176            /etc/group[-+]?
177            /etc/passwd[-+]?
178            /etc/passwd.adjunct.*

186
187            /selinux

189       shadow_t
190
191            /etc/shadow.*
192            /etc/gshadow.*
193            /etc/nshadow.*
194            /var/db/shadow.*

FILE CONTEXTS

200       SELinux requires files to have an extended attribute to define the file
201       type.
202
203       You can see the context of a file using the -Z option to ls
204
205       Policy  governs  the  access  confined  processes  have to these files.
206       SELinux groupadd policy is very flexible allowing users to setup  their
207       groupadd processes in as secure a method as possible.
208
209       The following file types are defined for groupadd:
210
211
212
213       groupadd_exec_t
214
215       - Set files with the groupadd_exec_t type, if you want to transition an
216       executable to the groupadd_t domain.
217
218
219       Paths:
220            /usr/bin/gpasswd,      /usr/sbin/gpasswd,      /usr/sbin/groupadd,
221            /usr/sbin/groupdel, /usr/sbin/groupmod
222
223
224       Note:  File context can be temporarily modified with the chcon command.
225       If you want to permanently change the file context you need to use  the
226       semanage fcontext command.  This will modify the SELinux labeling data‐
227       base.  You will need to use restorecon to apply the labels.
228
229

COMMANDS

231       semanage fcontext can also be used to manipulate default  file  context
232       mappings.
233
234       semanage  permissive  can  also  be used to manipulate whether or not a
235       process type is permissive.
236
237       semanage module can also be used to enable/disable/install/remove  pol‐
238       icy modules.
239
240       semanage boolean can also be used to manipulate the booleans
241
242
243       system-config-selinux is a GUI tool available to customize SELinux pol‐
244       icy settings.
