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.

59
60 If you want to dontaudit all daemons scheduling requests (setsched,
61 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
62 Enabled by default.
63
64 setsebool -P daemons_dontaudit_scheduling 1
65
66
67
68 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70
71 setsebool -P fips_mode 1
72
73
74
75 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Enabled by default.
77
78 setsebool -P kerberos_enabled 1
79
80
81
82 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84
85 setsebool -P nis_enabled 1
86
87

90 The SELinux process type dovecot_t can manage files labeled with the
91 following file types. The paths listed are the default paths for these
92 file types. Note the processes UID still need to have DAC permissions.

211 SELinux requires files to have an extended attribute to define the file
212 type.
213
214 You can see the context of a file using the -Z option to ls
215
216 Policy governs the access confined processes have to these files.
217 SELinux dovecot policy is very flexible allowing users to setup their
218 dovecot processes in as secure a method as possible.
219
220 EQUIVALENCE DIRECTORIES
221
222
223 dovecot policy stores data with multiple different file context types
224 under the /var/log/dovecot directory. If you would like to store the
225 data in a different directory you can use the semanage command to cre‐
226 ate an equivalence mapping. If you wanted to store this data under the
227 /srv directory you would execute the following command:
228
229 semanage fcontext -a -e /var/log/dovecot /srv/dovecot
230 restorecon -R -v /srv/dovecot
231
232 STANDARD FILE CONTEXT
233
234 SELinux defines the file context types for the dovecot, if you wanted
235 to store files with these types in a different paths, you need to exe‐
236 cute the semanage command to specify alternate labeling and then use
237 restorecon to put the labels on disk.
238
239 semanage fcontext -a -t dovecot_exec_t '/srv/dovecot/content(/.*)?'
240 restorecon -R -v /srv/mydovecot_content
241
242 Note: SELinux often uses regular expressions to specify labels that
243 match multiple files.
244

371
372
373
374 Note: File context can be temporarily modified with the chcon command.
375 If you want to permanently change the file context you need to use the
376 semanage fcontext command. This will modify the SELinux labeling data‐
377 base. You will need to use restorecon to apply the labels.
378
379
381 semanage fcontext can also be used to manipulate default file context
382 mappings.
383
384 semanage permissive can also be used to manipulate whether or not a
385 process type is permissive.
386
387 semanage module can also be used to enable/disable/install/remove pol‐
388 icy modules.
389
390 semanage boolean can also be used to manipulate the booleans
391

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