6 dovecot_auth_selinux - Security Enhanced Linux Policy for the dove‐
7 cot_auth processes
8
10 Security-Enhanced Linux secures the dovecot_auth processes via flexible
11 mandatory access control.
12
13 The dovecot_auth processes execute with the dovecot_auth_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep dovecot_auth_t
20
21
22
24 The dovecot_auth_t SELinux type can be entered via the dove‐
25 cot_auth_exec_t file type.
26
27 The default entrypoint paths for the dovecot_auth_t domain are the fol‐
28 lowing:
29
30 /usr/libexec/dovecot/auth, /usr/libexec/dovecot/dovecot-auth
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_auth policy is very flexible allowing users to setup their
40 dovecot_auth processes in as secure a method as possible.
41
42 The following process types are defined for dovecot_auth:
43
44 dovecot_auth_t
45
46 Note: semanage permissive -a dovecot_auth_t can be used to make the
47 process type dovecot_auth_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required. dove‐
54 cot_auth policy is extremely flexible and has several booleans that al‐
55 low you to manipulate the policy and run dovecot_auth with the tightest
56 access possible.
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 system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69
70 setsebool -P nis_enabled 1
71
72
73
75 The SELinux process type dovecot_auth_t can manage files labeled with
76 the following file types. The paths listed are the default paths for
77 these file types. Note the processes UID still need to have DAC per‐
78 missions.

117 SELinux requires files to have an extended attribute to define the file
118 type.
119
120 You can see the context of a file using the -Z option to ls
121
122 Policy governs the access confined processes have to these files.
123 SELinux dovecot_auth policy is very flexible allowing users to setup
124 their dovecot_auth processes in as secure a method as possible.
125
126 STANDARD FILE CONTEXT
127
128 SELinux defines the file context types for the dovecot_auth, if you
129 wanted to store files with these types in a diffent paths, you need to
130 execute the semanage command to specify alternate labeling and then use
131 restorecon to put the labels on disk.
132
133 semanage fcontext -a -t dovecot_auth_tmp_t '/srv/mydovecot_auth_con‐
134 tent(/.*)?'
135 restorecon -R -v /srv/mydovecot_auth_content
136
137 Note: SELinux often uses regular expressions to specify labels that
138 match multiple files.
139
140 The following file types are defined for dovecot_auth:
141
142
143
144 dovecot_auth_exec_t
145
146 - Set files with the dovecot_auth_exec_t type, if you want to transi‐
147 tion an executable to the dovecot_auth_t domain.
148
149
150 Paths:
151 /usr/libexec/dovecot/auth, /usr/libexec/dovecot/dovecot-auth
152
153
154 dovecot_auth_tmp_t
155
156 - Set files with the dovecot_auth_tmp_t type, if you want to store
157 dovecot auth temporary files in the /tmp directories.
158
159
160
161 Note: File context can be temporarily modified with the chcon command.
162 If you want to permanently change the file context you need to use the
163 semanage fcontext command. This will modify the SELinux labeling data‐
164 base. You will need to use restorecon to apply the labels.
165
166
168 semanage fcontext can also be used to manipulate default file context
169 mappings.
170
171 semanage permissive can also be used to manipulate whether or not a
172 process type is permissive.
173
174 semanage module can also be used to enable/disable/install/remove pol‐
175 icy modules.
176
177 semanage boolean can also be used to manipulate the booleans
178
179
180 system-config-selinux is a GUI tool available to customize SELinux pol‐
181 icy settings.
