6 groupadd_selinux - Security Enhanced Linux Policy for the groupadd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the groupadd processes via flexible
11 mandatory access control.
12 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 For example:
18 ps -eZ | grep groupadd_t
20
24 The groupadd_t SELinux type can be entered via the groupadd_exec_t file
25 type.
26 The default entrypoint paths for the groupadd_t domain are the follow‐
28 ing:
29 /usr/bin/gpasswd, /usr/sbin/gpasswd, /usr/sbin/groupadd,
31 /usr/sbin/groupdel, /usr/sbin/groupmod
32
34 SELinux defines process types (domains) for each process running on the
35 system
36 You can see the context of a process using the -Z option to ps
38 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 The following process types are defined for groupadd:
44 groupadd_t
46 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
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.
58 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‐
63 gin_nsswitch_use_ldap boolean. Disabled by default.
64 setsebool -P authlogin_nsswitch_use_ldap 1
66 If you want to allow all domains to execute in fips_mode, you must turn
70 on the fips_mode boolean. Enabled by default.
71 setsebool -P fips_mode 1
73 If you want to allow confined applications to run with kerberos, you
77 must turn on the kerberos_enabled boolean. Enabled by default.
78 setsebool -P kerberos_enabled 1
80 If you want to allow system to run with NIS, you must turn on the
84 nis_enabled boolean. Disabled by default.
85 setsebool -P nis_enabled 1
87 If you want to allow confined applications to use nscd shared memory,
91 you must turn on the nscd_use_shm boolean. Disabled by default.
92 setsebool -P nscd_use_shm 1
94 If you want to allow samba to act as the domain controller, add users,
98 groups and change passwords, you must turn on the samba_domain_con‐
99 troller boolean. Disabled by default.
100 setsebool -P samba_domain_controller 1

106 The SELinux process type groupadd_t can manage files labeled with the
107 following file types. The paths listed are the default paths for these
108 file types. Note the processes UID still need to have DAC permissions.
109 faillog_t
111 /var/log/btmp.*
113 /var/log/faillog.*
114 /var/log/tallylog.*
115 /var/run/faillock(/.*)?
116 lastlog_t
118 /var/log/lastlog.*
120 passwd_file_t
122 /etc/group[-+]?
124 /etc/passwd[-+]?
125 /etc/passwd.adjunct.*

156 SELinux requires files to have an extended attribute to define the file
157 type.
158 You can see the context of a file using the -Z option to ls
160 Policy governs the access confined processes have to these files.
162 SELinux groupadd policy is very flexible allowing users to setup their
163 groupadd processes in as secure a method as possible.
164 The following file types are defined for groupadd:
166 groupadd_exec_t
170 - Set files with the groupadd_exec_t type, if you want to transition an
172 executable to the groupadd_t domain.
173 Paths:
176 /usr/bin/gpasswd, /usr/sbin/gpasswd, /usr/sbin/groupadd,
177 /usr/sbin/groupdel, /usr/sbin/groupmod
178 Note: File context can be temporarily modified with the chcon command.
181 If you want to permanently change the file context you need to use the
182 semanage fcontext command. This will modify the SELinux labeling data‐
183 base. You will need to use restorecon to apply the labels.
184
187 semanage fcontext can also be used to manipulate default file context
188 mappings.
189 semanage permissive can also be used to manipulate whether or not a
191 process type is permissive.
192 semanage module can also be used to enable/disable/install/remove pol‐
194 icy modules.
195 semanage boolean can also be used to manipulate the booleans
197 system-config-selinux is a GUI tool available to customize SELinux pol‐
200 icy settings.
