dovecot_selinux(8) dovecot SELinux Policy documentation dovecot_selinux(8)NAMEdovecot_selinux - Security Enhanced Linux Policy for the dovecot pro‐
cesses
DESCRIPTION
Security-Enhanced Linux secures the dovecot processes via flexible
mandatory access control.
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the dove‐
cot_auth_t, dovecot_t, dovecot_deliver_t, you must turn on the authlo‐
gin_nsswitch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the
dovecot_auth_t, dovecot_t, dovecot_deliver_t, you must turn on the
allow_kerberos boolean.
setsebool -P allow_kerberos 1
If you want to allow system to run with NI for the dovecot_auth_t,
dovecot_t, dovecot_deliver_t, you must turn on the allow_ypbind bool‐
ean.
setsebool -P allow_ypbind 1
FILE CONTEXTS
SELinux requires files to have an extended attribute to define the file
type.
You can see the context of a file using the -Z option to ls
Policy governs the access confined processes have to these files.
SELinux dovecot policy is very flexible allowing users to setup their
dovecot processes in as secure a method as possible.
The following file types are defined for dovecot:
dovecot_auth_exec_t
- Set files with the dovecot_auth_exec_t type, if you want to transi‐
tion an executable to the dovecot_auth_t domain.
Paths:
/usr/libexec/dovecot/auth, /usr/libexec/dovecot/dovecot-auth
dovecot_auth_tmp_t
- Set files with the dovecot_auth_tmp_t type, if you want to store
dovecot auth temporary files in the /tmp directories.
dovecot_cert_t
- Set files with the dovecot_cert_t type, if you want to treat the
files as dovecot certificate data.
Paths:
/usr/share/ssl/certs/dovecot.pem, /usr/share/ssl/private/dove‐
cot.pem, /etc/pki/dovecot(/.*)?
dovecot_deliver_exec_t
- Set files with the dovecot_deliver_exec_t type, if you want to tran‐
sition an executable to the dovecot_deliver_t domain.
Paths:
/usr/libexec/dovecot/dovecot-lda, /usr/libexec/dovecot/deliver
dovecot_deliver_tmp_t
- Set files with the dovecot_deliver_tmp_t type, if you want to store
dovecot deliver temporary files in the /tmp directories.
dovecot_etc_t
- Set files with the dovecot_etc_t type, if you want to store dovecot
files in the /etc directories.
Paths:
/etc/dovecot(/.*)?*, /etc/dovecot.conf.*
dovecot_exec_t
- Set files with the dovecot_exec_t type, if you want to transition an
executable to the dovecot_t domain.
dovecot_initrc_exec_t
- Set files with the dovecot_initrc_exec_t type, if you want to transi‐
tion an executable to the dovecot_initrc_t domain.
dovecot_keytab_t
- Set files with the dovecot_keytab_t type, if you want to treat the
files as kerberos keytab files.
dovecot_passwd_t
- Set files with the dovecot_passwd_t type, if you want to treat the
files as dovecot passwd data.
dovecot_spool_t
- Set files with the dovecot_spool_t type, if you want to store the
dovecot files under the /var/spool directory.
dovecot_tmp_t
- Set files with the dovecot_tmp_t type, if you want to store dovecot
temporary files in the /tmp directories.
dovecot_var_lib_t
- Set files with the dovecot_var_lib_t type, if you want to store the
dovecot files under the /var/lib directory.
Paths:
/var/run/dovecot/login/ssl-parameters.dat, /var/lib/dovecot(/.*)?
dovecot_var_log_t
- Set files with the dovecot_var_log_t type, if you want to treat the
data as dovecot var log data, usually stored under the /var/log direc‐
tory.
Paths:
/var/log/dovecot.log.*, /var/log/dovecot(/.*)?
dovecot_var_run_t
- Set files with the dovecot_var_run_t type, if you want to store the
dovecot files under the /run directory.
Note: File context can be temporarily modified with the chcon command.
If you want to permanantly change the file context you need to use the
semanage fcontext command. This will modify the SELinux labeling data‐
base. You will need to use restorecon to apply the labels.
PROCESS TYPES
SELinux defines process types (domains) for each process running on the
system
You can see the context of a process using the -Z option to ps
Policy governs the access confined processes have to files. SELinux
dovecot policy is very flexible allowing users to setup their dovecot
processes in as secure a method as possible.
The following process types are defined for dovecot:
dovecot_deliver_t, dovecot_auth_t, dovecot_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process
type permissive. Permissive process types are not denied access by
SELinux. AVC messages will still be generated.
COMMANDS
semanage fcontext can also be used to manipulate default file context
mappings.
semanage permissive can also be used to manipulate whether or not a
process type is permissive.
semanage module can also be used to enable/disable/install/remove pol‐
icy modules.
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
