6 dictd_selinux - Security Enhanced Linux Policy for the dictd processes
7
9 Security-Enhanced Linux secures the dictd processes via flexible manda‐
10 tory access control.
11
12 The dictd processes execute with the dictd_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 dictd_t
19
20
21
23 The dictd_t SELinux type can be entered via the dictd_exec_t file type.
24
25 The default entrypoint paths for the dictd_t domain are the following:
26
27 /usr/sbin/dictd
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 dictd policy is very flexible allowing users to setup their dictd pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for dictd:
40
41 dictd_t
42
43 Note: semanage permissive -a dictd_t can be used to make the process
44 type dictd_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. dictd
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run dictd with the tightest access possible.
53
54
55
56 If you want to allow users to resolve user passwd entries directly from
57 ldap rather then using a sssd server, you must turn on the authlo‐
58 gin_nsswitch_use_ldap boolean. Disabled by default.
59
60 setsebool -P authlogin_nsswitch_use_ldap 1
61
62
63
64 If you want to allow all domains to execute in fips_mode, you must turn
65 on the fips_mode boolean. Enabled by default.
66
67 setsebool -P fips_mode 1
68
69
70
71 If you want to allow confined applications to run with kerberos, you
72 must turn on the kerberos_enabled boolean. Enabled by default.
73
74 setsebool -P kerberos_enabled 1
75
76
77
78 If you want to allow system to run with NIS, you must turn on the
79 nis_enabled boolean. Disabled by default.
80
81 setsebool -P nis_enabled 1
82
83
84
85 If you want to allow confined applications to use nscd shared memory,
86 you must turn on the nscd_use_shm boolean. Enabled by default.
87
88 setsebool -P nscd_use_shm 1
89

91
93 SELinux defines port types to represent TCP and UDP ports.
94
95 You can see the types associated with a port by using the following
96 command:
97
98 semanage port -l
99
100
101 Policy governs the access confined processes have to these ports.
102 SELinux dictd policy is very flexible allowing users to setup their
103 dictd processes in as secure a method as possible.
104
105 The following port types are defined for dictd:
106
107
108 dict_port_t
109
110
111
112 Default Defined Ports:
113 tcp 2628
114
116 The SELinux process type dictd_t can manage files labeled with the fol‐
117 lowing file types. The paths listed are the default paths for these
118 file types. Note the processes UID still need to have DAC permissions.

161 SELinux requires files to have an extended attribute to define the file
162 type.
163
164 You can see the context of a file using the -Z option to ls
165
166 Policy governs the access confined processes have to these files.
167 SELinux dictd policy is very flexible allowing users to setup their
168 dictd processes in as secure a method as possible.
169
170 STANDARD FILE CONTEXT
171
172 SELinux defines the file context types for the dictd, if you wanted to
173 store files with these types in a diffent paths, you need to execute
174 the semanage command to sepecify alternate labeling and then use
175 restorecon to put the labels on disk.
176
177 semanage fcontext -a -t dictd_var_run_t '/srv/mydictd_content(/.*)?'
178 restorecon -R -v /srv/mydictd_content
179
180 Note: SELinux often uses regular expressions to specify labels that
181 match multiple files.
182
183 The following file types are defined for dictd:
184
185
186
187 dictd_etc_t
188
189 - Set files with the dictd_etc_t type, if you want to store dictd files
190 in the /etc directories.
191
192
193
194 dictd_exec_t
195
196 - Set files with the dictd_exec_t type, if you want to transition an
197 executable to the dictd_t domain.
198
199
200
201 dictd_initrc_exec_t
202
203 - Set files with the dictd_initrc_exec_t type, if you want to transi‐
204 tion an executable to the dictd_initrc_t domain.
205
206
207
208 dictd_var_lib_t
209
210 - Set files with the dictd_var_lib_t type, if you want to store the
211 dictd files under the /var/lib directory.
212
213
214
215 dictd_var_run_t
216
217 - Set files with the dictd_var_run_t type, if you want to store the
218 dictd files under the /run or /var/run directory.
219
220
221
222 Note: File context can be temporarily modified with the chcon command.
223 If you want to permanently change the file context you need to use the
224 semanage fcontext command. This will modify the SELinux labeling data‐
225 base. You will need to use restorecon to apply the labels.
226
227
229 semanage fcontext can also be used to manipulate default file context
230 mappings.
231
232 semanage permissive can also be used to manipulate whether or not a
233 process type is permissive.
234
235 semanage module can also be used to enable/disable/install/remove pol‐
236 icy modules.
237
238 semanage port can also be used to manipulate the port definitions
239
240 semanage boolean can also be used to manipulate the booleans
241
242
243 system-config-selinux is a GUI tool available to customize SELinux pol‐
244 icy settings.
