6 spamd_selinux - Security Enhanced Linux Policy for the spamd processes
7
9 Security-Enhanced Linux secures the spamd processes via flexible manda‐
10 tory access control.
11 The spamd processes execute with the spamd_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15 For example:
17 ps -eZ | grep spamd_t
19
23 The spamd_t SELinux type can be entered via the spamd_exec_t file type.
24 The default entrypoint paths for the spamd_t domain are the following:
26 /usr/bin/spamd, /usr/bin/pyzord, /usr/sbin/spamd, /usr/sbin/spampd,
28 /usr/bin/mimedefang, /usr/bin/mimedefang-multiplexor,
29 /usr/libexec/mimedefang-wrapper
30
32 SELinux defines process types (domains) for each process running on the
33 system
34 You can see the context of a process using the -Z option to ps
36 Policy governs the access confined processes have to files. SELinux
38 spamd policy is very flexible allowing users to setup their spamd pro‐
39 cesses in as secure a method as possible.
40 The following process types are defined for spamd:
42 spamd_update_t, spamd_t
44 Note: semanage permissive -a spamd_t can be used to make the process
46 type spamd_t permissive. SELinux does not deny access to permissive
47 process types, but the AVC (SELinux denials) messages are still gener‐
48 ated.
49
52 SELinux policy is customizable based on least access required. spamd
53 policy is extremely flexible and has several booleans that allow you to
54 manipulate the policy and run spamd with the tightest access possible.
55 If you want to allow spamd to read/write user home directories, you
59 must turn on the spamd_enable_home_dirs boolean. Disabled by default.
60 setsebool -P spamd_enable_home_dirs 1
62 If you want to allow users to resolve user passwd entries directly from
66 ldap rather then using a sssd server, you must turn on the authlo‐
67 gin_nsswitch_use_ldap boolean. Disabled by default.
68 setsebool -P authlogin_nsswitch_use_ldap 1
70 If you want to allow all domains to execute in fips_mode, you must turn
74 on the fips_mode boolean. Enabled by default.
75 setsebool -P fips_mode 1
77 If you want to allow confined applications to run with kerberos, you
81 must turn on the kerberos_enabled boolean. Disabled by default.
82 setsebool -P kerberos_enabled 1
84 If you want to allow system to run with NIS, you must turn on the
88 nis_enabled boolean. Disabled by default.
89 setsebool -P nis_enabled 1
91 If you want to allow confined applications to use nscd shared memory,
95 you must turn on the nscd_use_shm boolean. Disabled by default.
96 setsebool -P nscd_use_shm 1
98
102 SELinux defines port types to represent TCP and UDP ports.
103 You can see the types associated with a port by using the following
105 command:
106 semanage port -l
108 Policy governs the access confined processes have to these ports.
111 SELinux spamd policy is very flexible allowing users to setup their
112 spamd processes in as secure a method as possible.
113 The following port types are defined for spamd:
115 spamd_port_t
118 Default Defined Ports:
122 tcp 783,10026,10027
123
125 The SELinux process type spamd_t can manage files labeled with the fol‐
126 lowing file types. The paths listed are the default paths for these
127 file types. Note the processes UID still need to have DAC permissions.

267 SELinux requires files to have an extended attribute to define the file
268 type.
269 You can see the context of a file using the -Z option to ls
271 Policy governs the access confined processes have to these files.
273 SELinux spamd policy is very flexible allowing users to setup their
274 spamd processes in as secure a method as possible.
275 EQUIVALENCE DIRECTORIES
277 spamd policy stores data with multiple different file context types
280 under the /var/lib/spamassassin directory. If you would like to store
281 the data in a different directory you can use the semanage command to
282 create an equivalence mapping. If you wanted to store this data under
283 the /srv dirctory you would execute the following command:
284 semanage fcontext -a -e /var/lib/spamassassin /srv/spamassassin
286 restorecon -R -v /srv/spamassassin
287 STANDARD FILE CONTEXT
289 SELinux defines the file context types for the spamd, if you wanted to
291 store files with these types in a diffent paths, you need to execute
292 the semanage command to sepecify alternate labeling and then use
293 restorecon to put the labels on disk.
294 semanage fcontext -a -t spamd_etc_t '/srv/myspamd_content(/.*)?'
296 restorecon -R -v /srv/myspamd_content
297 Note: SELinux often uses regular expressions to specify labels that
299 match multiple files.
300 The following file types are defined for spamd:
302 spamd_compiled_t
306 - Set files with the spamd_compiled_t type, if you want to treat the
308 files as spamd compiled data.
309 spamd_etc_t
313 - Set files with the spamd_etc_t type, if you want to store spamd files
315 in the /etc directories.
316 Paths:
319 /etc/pyzor(/.*)?, /etc/razor(/.*)?
320 spamd_exec_t
323 - Set files with the spamd_exec_t type, if you want to transition an
325 executable to the spamd_t domain.
326 Paths:
329 /usr/bin/spamd, /usr/bin/pyzord, /usr/sbin/spamd,
330 /usr/sbin/spampd, /usr/bin/mimedefang, /usr/bin/mimedefang-multi‐
331 plexor, /usr/libexec/mimedefang-wrapper
332 spamd_initrc_exec_t
335 - Set files with the spamd_initrc_exec_t type, if you want to transi‐
337 tion an executable to the spamd_initrc_t domain.
338 Paths:
341 /etc/rc.d/init.d/mimedefang.*, /etc/rc.d/init.d/spamd,
342 /etc/rc.d/init.d/pyzord, /etc/rc.d/init.d/spampd
343 spamd_log_t
346 - Set files with the spamd_log_t type, if you want to treat the data as
348 spamd log data, usually stored under the /var/log directory.
349 Paths:
352 /var/log/spamd.log.*, /var/log/mimedefang.*,
353 /var/log/pyzord.log.*, /var/log/sa-update.log.*, /var/log/razor-
354 agent.log.*
355 spamd_spool_t
358 - Set files with the spamd_spool_t type, if you want to store the spamd
360 files under the /var/spool directory.
361 Paths:
364 /var/spool/spamd(/.*)?, /var/spool/spampd(/.*)?, /var/spool/spa‐
365 massassin(/.*)?
366 spamd_tmp_t
369 - Set files with the spamd_tmp_t type, if you want to store spamd tem‐
371 porary files in the /tmp directories.
372 spamd_update_exec_t
376 - Set files with the spamd_update_exec_t type, if you want to transi‐
378 tion an executable to the spamd_update_t domain.
379 Paths:
382 /usr/share/spamassassin/sa-update.cron, /usr/bin/sa-update
383 spamd_var_lib_t
386 - Set files with the spamd_var_lib_t type, if you want to store the
388 spamd files under the /var/lib directory.
389 Paths:
392 /var/lib/razor(/.*)?, /var/lib/pyzord(/.*)?, /var/lib/spamassas‐
393 sin(/.*)?
394 spamd_var_run_t
397 - Set files with the spamd_var_run_t type, if you want to store the
399 spamd files under the /run or /var/run directory.
400 Paths:
403 /var/run/spamassassin(/.*)?, /var/spool/MIMEDefang(/.*)?,
404 /var/spool/MD-Quarantine(/.*)?
405 Note: File context can be temporarily modified with the chcon command.
408 If you want to permanently change the file context you need to use the
409 semanage fcontext command. This will modify the SELinux labeling data‐
410 base. You will need to use restorecon to apply the labels.
411
414 semanage fcontext can also be used to manipulate default file context
415 mappings.
416 semanage permissive can also be used to manipulate whether or not a
418 process type is permissive.
419 semanage module can also be used to enable/disable/install/remove pol‐
421 icy modules.
422 semanage port can also be used to manipulate the port definitions
424 semanage boolean can also be used to manipulate the booleans
426 system-config-selinux is a GUI tool available to customize SELinux pol‐
429 icy settings.
