6 utempter_selinux - Security Enhanced Linux Policy for the utempter pro‐
7 cesses
8
10 Security-Enhanced Linux secures the utempter processes via flexible
11 mandatory access control.
12
13 The utempter processes execute with the utempter_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 utempter_t
20
21
22
24 The utempter_t SELinux type can be entered via the utempter_exec_t file
25 type.
26
27 The default entrypoint paths for the utempter_t domain are the follow‐
28 ing:
29
30 /usr/sbin/utempter, /usr/libexec/utempter/utempter
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 utempter policy is very flexible allowing users to setup their utempter
40 processes in as secure a method as possible.
41
42 The following process types are defined for utempter:
43
44 utempter_t
45
46 Note: semanage permissive -a utempter_t can be used to make the process
47 type utempter_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.
54 utempter policy is extremely flexible and has several booleans that al‐
55 low you to manipulate the policy and run utempter with the tightest ac‐
56 cess possible.
57
58
59
60 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1
64
65
66
67 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69
70 setsebool -P nis_enabled 1
71
72
73
75 The SELinux process type utempter_t can manage files labeled with the
76 following file types. The paths listed are the default paths for these
77 file types. Note the processes UID still need to have DAC permissions.

82 /var/run/random-seed

99
100 wtmp_t

102 /var/log/wtmp.*
103
104
106 SELinux requires files to have an extended attribute to define the file
107 type.
108
109 You can see the context of a file using the -Z option to ls
110
111 Policy governs the access confined processes have to these files.
112 SELinux utempter policy is very flexible allowing users to setup their
113 utempter processes in as secure a method as possible.
114
115 STANDARD FILE CONTEXT
116
117 SELinux defines the file context types for the utempter, if you wanted
118 to store files with these types in a different paths, you need to exe‐
119 cute the semanage command to specify alternate labeling and then use
120 restorecon to put the labels on disk.
121
122 semanage fcontext -a -t utempter_exec_t '/srv/utempter/content(/.*)?'
123 restorecon -R -v /srv/myutempter_content
124
125 Note: SELinux often uses regular expressions to specify labels that
126 match multiple files.
127
128 The following file types are defined for utempter:
129
130
131
132 utempter_exec_t
133
134 - Set files with the utempter_exec_t type, if you want to transition an
135 executable to the utempter_t domain.
136
137
138 Paths:
139 /usr/sbin/utempter, /usr/libexec/utempter/utempter
140
141
142 Note: File context can be temporarily modified with the chcon command.
143 If you want to permanently change the file context you need to use the
144 semanage fcontext command. This will modify the SELinux labeling data‐
145 base. You will need to use restorecon to apply the labels.
146
147
149 semanage fcontext can also be used to manipulate default file context
150 mappings.
151
152 semanage permissive can also be used to manipulate whether or not a
153 process type is permissive.
154
155 semanage module can also be used to enable/disable/install/remove pol‐
156 icy modules.
157
158 semanage boolean can also be used to manipulate the booleans
159
160
161 system-config-selinux is a GUI tool available to customize SELinux pol‐
162 icy settings.
