6 dovecot_selinux - Security Enhanced Linux Policy for the dovecot pro‐
7 cesses
8
10 Security-Enhanced Linux secures the dovecot processes via flexible
11 mandatory access control.
12
13 The dovecot processes execute with the dovecot_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 dovecot_t
20
21
22
24 The dovecot_t SELinux type can be entered via the dovecot_exec_t file
25 type.
26
27 The default entrypoint paths for the dovecot_t domain are the follow‐
28 ing:
29
30 /usr/sbin/dovecot
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 dovecot policy is very flexible allowing users to setup their dovecot
40 processes in as secure a method as possible.
41
42 The following process types are defined for dovecot:
43
44 dovecot_t, dovecot_auth_t, dovecot_deliver_t
45
46 Note: semanage permissive -a dovecot_t can be used to make the process
47 type dovecot_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. dovecot
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run dovecot with the tightest access possi‐
56 ble.
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 confined applications to run with kerberos, you
68 must turn on the kerberos_enabled boolean. Enabled by default.
69
70 setsebool -P kerberos_enabled 1
71
72
73
75 The SELinux process type dovecot_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.

203 dovecot processes in as secure a method as possible.
204
205 EQUIVALENCE DIRECTORIES
206
207
208 dovecot policy stores data with multiple different file context types
209 under the /var/log/dovecot directory. If you would like to store the
210 data in a different directory you can use the semanage command to cre‐
211 ate an equivalence mapping. If you wanted to store this data under the
212 /srv directory you would execute the following command:
213
214 semanage fcontext -a -e /var/log/dovecot /srv/dovecot
215 restorecon -R -v /srv/dovecot
216
217 STANDARD FILE CONTEXT
218
219 SELinux defines the file context types for the dovecot, if you wanted
220 to store files with these types in a diffent paths, you need to execute
221 the semanage command to specify alternate labeling and then use re‐
222 storecon to put the labels on disk.
223
224 semanage fcontext -a -t dovecot_var_run_t '/srv/mydovecot_con‐
225 tent(/.*)?'
226 restorecon -R -v /srv/mydovecot_content
227
228 Note: SELinux often uses regular expressions to specify labels that
229 match multiple files.
230

360 Note: File context can be temporarily modified with the chcon command.
361 If you want to permanently change the file context you need to use the
362 semanage fcontext command. This will modify the SELinux labeling data‐
363 base. You will need to use restorecon to apply the labels.
364
365
367 semanage fcontext can also be used to manipulate default file context
368 mappings.
369
370 semanage permissive can also be used to manipulate whether or not a
371 process type is permissive.
372
373 semanage module can also be used to enable/disable/install/remove pol‐
374 icy modules.
375
376 semanage boolean can also be used to manipulate the booleans

379 system-config-selinux is a GUI tool available to customize SELinux pol‐
380 icy settings.
