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
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
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
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
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
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
84 The SELinux process type groupadd_t can manage files labeled with the
85 following file types. The paths listed are the default paths for these
86 file types. Note the processes UID still need to have DAC permissions.
87
88 faillog_t
89
90 /var/log/btmp.*
91 /var/log/faillog.*
92 /var/log/tallylog.*
93 /var/run/faillock(/.*)?
94
95 lastlog_t
96
97 /var/log/lastlog.*

100
101 /selinux
102
103 shadow_t
104
105 /etc/shadow.*
106 /etc/gshadow.*
107 /etc/nshadow.*
108 /var/db/shadow.*
109 /etc/security/opasswd
110 /etc/security/opasswd.old
111
112
114 SELinux requires files to have an extended attribute to define the file
115 type.
116
117 You can see the context of a file using the -Z option to ls
118
119 Policy governs the access confined processes have to these files.
120 SELinux groupadd policy is very flexible allowing users to setup their
121 groupadd processes in as secure a method as possible.
122
123 The following file types are defined for groupadd:
124
125
126
127 groupadd_exec_t
128
129 - Set files with the groupadd_exec_t type, if you want to transition an
130 executable to the groupadd_t domain.
131
132
133 Paths:
134 /usr/bin/gpasswd, /usr/sbin/gpasswd, /usr/sbin/groupadd,
135 /usr/sbin/groupdel, /usr/sbin/groupmod
136
137
138 Note: File context can be temporarily modified with the chcon command.
139 If you want to permanently change the file context you need to use the
140 semanage fcontext command. This will modify the SELinux labeling data‐
141 base. You will need to use restorecon to apply the labels.
142
143
145 semanage fcontext can also be used to manipulate default file context
146 mappings.
147
148 semanage permissive can also be used to manipulate whether or not a
149 process type is permissive.
150
151 semanage module can also be used to enable/disable/install/remove pol‐
152 icy modules.
153
154 semanage boolean can also be used to manipulate the booleans
155
156
157 system-config-selinux is a GUI tool available to customize SELinux pol‐
158 icy settings.
