6 getty_selinux - Security Enhanced Linux Policy for the getty processes
7
9 Security-Enhanced Linux secures the getty processes via flexible manda‐
10 tory access control.
11
12 The getty processes execute with the getty_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep getty_t
19
20
21
23 The getty_t SELinux type can be entered via the getty_exec_t file type.
24
25 The default entrypoint paths for the getty_t domain are the following:
26
27 /sbin/.*getty, /usr/sbin/.*getty
28
30 SELinux defines process types (domains) for each process running on the
31 system
32
33 You can see the context of a process using the -Z option to ps
34
35 Policy governs the access confined processes have to files. SELinux
36 getty policy is very flexible allowing users to setup their getty pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for getty:
40
41 getty_t
42
43 Note: semanage permissive -a getty_t can be used to make the process
44 type getty_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
48
50 SELinux policy is customizable based on least access required. getty
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run getty with the tightest access possible.
53
54
55
56 If you want to allow all domains to execute in fips_mode, you must turn
57 on the fips_mode boolean. Enabled by default.
58
59 setsebool -P fips_mode 1
60
61
62
63 If you want to allow system to run with NIS, you must turn on the
64 nis_enabled boolean. Disabled by default.
65
66 setsebool -P nis_enabled 1
67
68

71 The SELinux process type getty_t can manage files labeled with the fol‐
72 lowing file types. The paths listed are the default paths for these
73 file types. Note the processes UID still need to have DAC permissions.

116 SELinux requires files to have an extended attribute to define the file
117 type.
118
119 You can see the context of a file using the -Z option to ls
120
121 Policy governs the access confined processes have to these files.
122 SELinux getty policy is very flexible allowing users to setup their
123 getty processes in as secure a method as possible.
124
125 STANDARD FILE CONTEXT
126
127 SELinux defines the file context types for the getty, if you wanted to
128 store files with these types in a diffent paths, you need to execute
129 the semanage command to sepecify alternate labeling and then use
130 restorecon to put the labels on disk.
131
132 semanage fcontext -a -t getty_unit_file_t '/srv/mygetty_content(/.*)?'
133 restorecon -R -v /srv/mygetty_content
134
135 Note: SELinux often uses regular expressions to specify labels that
136 match multiple files.
137
138 The following file types are defined for getty:
139
140
141
142 getty_etc_t
143
144 - Set files with the getty_etc_t type, if you want to store getty files
145 in the /etc directories.
146
147
148
149 getty_exec_t
150
151 - Set files with the getty_exec_t type, if you want to transition an
152 executable to the getty_t domain.
153
154
155 Paths:
156 /sbin/.*getty, /usr/sbin/.*getty
157
158
159 getty_lock_t
160
161 - Set files with the getty_lock_t type, if you want to treat the files
162 as getty lock data, stored under the /var/lock directory
163
164
165
166 getty_log_t
167
168 - Set files with the getty_log_t type, if you want to treat the data as
169 getty log data, usually stored under the /var/log directory.
170
171
172 Paths:
173 /var/log/mgetty.*.log.*, /var/log/vgetty.*.log.*
174
175
176 getty_tmp_t
177
178 - Set files with the getty_tmp_t type, if you want to store getty tem‐
179 porary files in the /tmp directories.
180
181
182
183 getty_unit_file_t
184
185 - Set files with the getty_unit_file_t type, if you want to treat the
186 files as getty unit content.
187
188
189
190 getty_var_run_t
191
192 - Set files with the getty_var_run_t type, if you want to store the
193 getty files under the /run or /var/run directory.
194
195
196 Paths:
197 /var/spool/fax(/.*)?, /var/spool/voice(/.*)?,
198 /var/run/mgetty.pid.*, /var/run/agetty.reload.*
199
200
201 Note: File context can be temporarily modified with the chcon command.
202 If you want to permanently change the file context you need to use the
203 semanage fcontext command. This will modify the SELinux labeling data‐
204 base. You will need to use restorecon to apply the labels.
205
206
208 semanage fcontext can also be used to manipulate default file context
209 mappings.
210
211 semanage permissive can also be used to manipulate whether or not a
212 process type is permissive.
213
214 semanage module can also be used to enable/disable/install/remove pol‐
215 icy modules.
216
217 semanage boolean can also be used to manipulate the booleans
218
219
220 system-config-selinux is a GUI tool available to customize SELinux pol‐
221 icy settings.
