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 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 For example:
18 ps -eZ | grep dovecot_auth_t
20
24 The dovecot_auth_t SELinux type can be entered via the dove‐
25 cot_auth_exec_t file type.
26 The default entrypoint paths for the dovecot_auth_t domain are the fol‐
28 lowing:
29 /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 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for dovecot_auth:
43 dovecot_auth_t
45 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
53 SELinux policy is customizable based on least access required. dove‐
54 cot_auth policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run dovecot_auth with the tight‐
56 est access possible.
57 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63 setsebool -P authlogin_nsswitch_use_ldap 1
65 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 setsebool -P fips_mode 1
72 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Enabled by default.
77 setsebool -P kerberos_enabled 1
79 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84 setsebool -P nis_enabled 1
86 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Disabled by default.
91 setsebool -P nscd_use_shm 1
93
97 The SELinux process type dovecot_auth_t can manage files labeled with
98 the following file types. The paths listed are the default paths for
99 these file types. Note the processes UID still need to have DAC per‐
100 missions.
101 dovecot_auth_tmp_t
103 dovecot_var_run_t
106 /var/run/dovecot(-login)?(/.*)?
108 faillog_t
110 /var/log/btmp.*
112 /var/log/faillog.*
113 /var/log/tallylog.*
114 /var/run/faillock(/.*)?
115 initrc_var_run_t
117 /var/run/utmp
119 /var/run/random-seed
120 /var/run/runlevel.dir
121 /var/run/setmixer_flag
122
125 SELinux requires files to have an extended attribute to define the file
126 type.
127 You can see the context of a file using the -Z option to ls
129 Policy governs the access confined processes have to these files.
131 SELinux dovecot_auth policy is very flexible allowing users to setup
132 their dovecot_auth processes in as secure a method as possible.
133 STANDARD FILE CONTEXT
135 SELinux defines the file context types for the dovecot_auth, if you
137 wanted to store files with these types in a diffent paths, you need to
138 execute the semanage command to sepecify alternate labeling and then
139 use restorecon to put the labels on disk.
140 semanage fcontext -a -t dovecot_auth_tmp_t '/srv/mydovecot_auth_con‐
142 tent(/.*)?'
143 restorecon -R -v /srv/mydovecot_auth_content
144 Note: SELinux often uses regular expressions to specify labels that
146 match multiple files.
147 The following file types are defined for dovecot_auth:
149 dovecot_auth_exec_t
153 - Set files with the dovecot_auth_exec_t type, if you want to transi‐
155 tion an executable to the dovecot_auth_t domain.
156 Paths:
159 /usr/libexec/dovecot/auth, /usr/libexec/dovecot/dovecot-auth
160 dovecot_auth_tmp_t
163 - Set files with the dovecot_auth_tmp_t type, if you want to store
165 dovecot auth temporary files in the /tmp directories.
166 Note: File context can be temporarily modified with the chcon command.
170 If you want to permanently change the file context you need to use the
171 semanage fcontext command. This will modify the SELinux labeling data‐
172 base. You will need to use restorecon to apply the labels.
173
176 semanage fcontext can also be used to manipulate default file context
177 mappings.
178 semanage permissive can also be used to manipulate whether or not a
180 process type is permissive.
181 semanage module can also be used to enable/disable/install/remove pol‐
183 icy modules.
184 semanage boolean can also be used to manipulate the booleans
186 system-config-selinux is a GUI tool available to customize SELinux pol‐
189 icy settings.
