spamd_selinux(8) spamd SELinux Policy documentation spamd_selinux(8)NAMEspamd_selinux - Security Enhanced Linux Policy for the spamd processes
DESCRIPTION
Security-Enhanced Linux secures the spamd processes via flexible manda‐
tory access control.
BOOLEANS
SELinux policy is customizable based on least access required. spamd
policy is extremely flexible and has several booleans that allow you to
manipulate the policy and run spamd with the tightest access possible.
If you want to allow user spamassassin clients to use the network, you
must turn on the spamassassin_can_network boolean.
setsebool -P spamassassin_can_network 1
If you want to allow spamd to read/write user home directories, you
must turn on the spamd_enable_home_dirs boolean.
setsebool -P spamd_enable_home_dirs 1
If you want to allow http daemon to check spa, you must turn on the
httpd_can_check_spam boolean.
setsebool -P httpd_can_check_spam 1
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the spamc_t,
spamd_update_t, spamd_t, you must turn on the authlogin_nss‐
witch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the
spamc_t, spamd_update_t, spamd_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 spamc_t,
spamd_update_t, spamd_t, you must turn on the allow_ypbind boolean.
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 spamd policy is very flexible allowing users to setup their
spamd processes in as secure a method as possible.
The following file types are defined for spamd:
spamd_compiled_t
- Set files with the spamd_compiled_t type, if you want to treat the
files as spamd compiled data.
spamd_etc_t
- Set files with the spamd_etc_t type, if you want to store spamd files
in the /etc directories.
Paths:
/etc/pyzor(/.*)?, /etc/razor(/.*)?
spamd_exec_t
- Set files with the spamd_exec_t type, if you want to transition an
executable to the spamd_t domain.
Paths:
/usr/sbin/spamd, /usr/bin/mimedefang-multiplexor, /usr/bin/pyzord,
/usr/bin/spamd, /usr/bin/mimedefang
spamd_initrc_exec_t
- Set files with the spamd_initrc_exec_t type, if you want to transi‐
tion an executable to the spamd_initrc_t domain.
Paths:
/etc/rc.d/init.d/spamd, /etc/rc.d/init.d/mimedefang.*,
/etc/rc.d/init.d/pyzord
spamd_log_t
- Set files with the spamd_log_t type, if you want to treat the data as
spamd log data, usually stored under the /var/log directory.
Paths:
/var/log/razor-agent.log, /var/log/spamd.log, /var/log/mimedefang,
/var/log/pyzord.log
spamd_spool_t
- Set files with the spamd_spool_t type, if you want to store the spamd
files under the /var/spool directory.
Paths:
/var/spool/spamd(/.*)?, /var/spool/spamassassin(/.*)?
spamd_tmp_t
- Set files with the spamd_tmp_t type, if you want to store spamd tem‐
porary files in the /tmp directories.
spamd_update_exec_t
- Set files with the spamd_update_exec_t type, if you want to transi‐
tion an executable to the spamd_update_t domain.
spamd_var_lib_t
- Set files with the spamd_var_lib_t type, if you want to store the
spamd files under the /var/lib directory.
Paths:
/var/lib/spamassassin(/.*)?, /var/lib/razor(/.*)?,
/var/lib/pyzord(/.*)?
spamd_var_run_t
- Set files with the spamd_var_run_t type, if you want to store the
spamd files under the /run directory.
Paths:
/var/run/spamassassin(/.*)?, /var/spool/MIMEDefang(/.*)?,
/var/spool/MD-Quarantine(/.*)?
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.
PORT TYPES
SELinux defines port types to represent TCP and UDP ports.
You can see the types associated with a port by using the following
command:
semanage port -l
Policy governs the access confined processes have to these ports.
SELinux spamd policy is very flexible allowing users to setup their
spamd processes in as secure a method as possible.
The following port types are defined for spamd:
spamd_port_t
Default Defined Ports:
tcp 783
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
spamd policy is very flexible allowing users to setup their spamd pro‐
cesses in as secure a method as possible.
The following process types are defined for spamd:
spamc_t, spamd_t, spamd_update_t, spamass_milter_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.
semanage port can also be used to manipulate the port definitions
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
