6 kadmind_selinux - Security Enhanced Linux Policy for the kadmind pro‐
7 cesses
8
10 Security-Enhanced Linux secures the kadmind processes via flexible
11 mandatory access control.
12
13 The kadmind processes execute with the kadmind_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep kadmind_t
20
21
22
24 The kadmind_t SELinux type can be entered via the kadmind_exec_t file
25 type.
26
27 The default entrypoint paths for the kadmind_t domain are the follow‐
28 ing:
29
30 /usr/(kerberos/)?sbin/kadmind, /usr/(kerberos/)?sbin/_kadmind,
31 /usr/kerberos/sbin/kadmin.local
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 kadmind policy is very flexible allowing users to setup their kadmind
41 processes in as secure a method as possible.
42
43 The following process types are defined for kadmind:
44
45 kadmind_t
46
47 Note: semanage permissive -a kadmind_t can be used to make the process
48 type kadmind_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. kadmind
55 policy is extremely flexible and has several booleans that allow you to
56 manipulate the policy and run kadmind with the tightest access possi‐
57 ble.
58

60
61 If you want to dontaudit all daemons scheduling requests (setsched,
62 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
63 Enabled by default.
64
65 setsebool -P daemons_dontaudit_scheduling 1
66
67
68
69 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
72 setsebool -P fips_mode 1
73
74
75
76 If you want to allow system to run with NIS, you must turn on the
77 nis_enabled boolean. Disabled by default.
78
79 setsebool -P nis_enabled 1
80
81
82
84 The SELinux process type kadmind_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.

173 SELinux requires files to have an extended attribute to define the file
174 type.
175
176 You can see the context of a file using the -Z option to ls
177
178 Policy governs the access confined processes have to these files.
179 SELinux kadmind policy is very flexible allowing users to setup their
180 kadmind processes in as secure a method as possible.
181
182 STANDARD FILE CONTEXT
183
184 SELinux defines the file context types for the kadmind, if you wanted
185 to store files with these types in a different paths, you need to exe‐
186 cute the semanage command to specify alternate labeling and then use
187 restorecon to put the labels on disk.
188
189 semanage fcontext -a -t kadmind_exec_t '/srv/kadmind/content(/.*)?'
190 restorecon -R -v /srv/mykadmind_content
191
192 Note: SELinux often uses regular expressions to specify labels that
193 match multiple files.
194
195 The following file types are defined for kadmind:
196
197
198
199 kadmind_exec_t
200
201 - Set files with the kadmind_exec_t type, if you want to transition an
202 executable to the kadmind_t domain.
203
204
205 Paths:
206 /usr/(kerberos/)?sbin/kadmind, /usr/(kerberos/)?sbin/_kadmind,
207 /usr/kerberos/sbin/kadmin.local
208
209
210 kadmind_log_t
211
212 - Set files with the kadmind_log_t type, if you want to treat the data
213 as kadmind log data, usually stored under the /var/log directory.
214
215
216
217 kadmind_tmp_t
218
219 - Set files with the kadmind_tmp_t type, if you want to store kadmind
220 temporary files in the /tmp directories.
221
222
223 Paths:
224 /var/tmp/kadmin_0, /var/tmp/kiprop_0
225
226
227 kadmind_var_run_t
228
229 - Set files with the kadmind_var_run_t type, if you want to store the
230 kadmind files under the /run or /var/run directory.
231
232
233
234 Note: File context can be temporarily modified with the chcon command.
235 If you want to permanently change the file context you need to use the
236 semanage fcontext command. This will modify the SELinux labeling data‐
237 base. You will need to use restorecon to apply the labels.
238
239
241 semanage fcontext can also be used to manipulate default file context
242 mappings.
243
244 semanage permissive can also be used to manipulate whether or not a
245 process type is permissive.
246
247 semanage module can also be used to enable/disable/install/remove pol‐
248 icy modules.
249
250 semanage boolean can also be used to manipulate the booleans
251
252
253 system-config-selinux is a GUI tool available to customize SELinux pol‐
254 icy settings.
