NAME

6       zabbix_selinux  -  Security  Enhanced  Linux Policy for the zabbix pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux  secures  the  zabbix  processes  via  flexible
11       mandatory access control.
12
13       The  zabbix  processes  execute with the zabbix_t SELinux type. You can
14       check if you have these processes running by executing the  ps  command
15       with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep zabbix_t
20
21
22

ENTRYPOINTS

24       The  zabbix_t  SELinux  type  can be entered via the zabbix_exec_t file
25       type.
26
27       The default entrypoint paths for the zabbix_t domain are the following:
28
29       /usr/(s)?bin/zabbix_server,   /usr/sbin/zabbix_proxy,    /usr/sbin/zab‐
30       bix_proxy_mysql,      /usr/sbin/zabbix_proxy_pgsql,      /usr/sbin/zab‐
31       bix_server_mysql,     /usr/sbin/zabbix_server_pgsql,     /usr/sbin/zab‐
32       bix_proxy_sqlite3, /usr/sbin/zabbix_server_sqlite3
33

PROCESS TYPES

35       SELinux defines process types (domains) for each process running on the
36       system
37
38       You can see the context of a process using the -Z option to ps
39
40       Policy governs the access confined processes have  to  files.   SELinux
41       zabbix  policy  is  very  flexible allowing users to setup their zabbix
42       processes in as secure a method as possible.
43
44       The following process types are defined for zabbix:
45
46       zabbix_script_t, zabbix_agent_t, zabbix_t
47
48       Note: semanage permissive -a zabbix_t can be used to make  the  process
49       type  zabbix_t  permissive.  SELinux does not deny access to permissive
50       process types, but the AVC (SELinux denials) messages are still  gener‐
51       ated.
52
53

BOOLEANS

55       SELinux  policy is customizable based on least access required.  zabbix
56       policy is extremely flexible and has several booleans that allow you to
57       manipulate the policy and run zabbix with the tightest access possible.

PORT TYPES

162       SELinux defines port types to represent TCP and UDP ports.
163
164       You  can  see  the  types associated with a port by using the following
165       command:
166
167       semanage port -l
168
169
170       Policy governs the access  confined  processes  have  to  these  ports.
171       SELinux  zabbix  policy  is very flexible allowing users to setup their
172       zabbix processes in as secure a method as possible.
173
174       The following port types are defined for zabbix:
175
176
177       zabbix_agent_port_t
178
179
180
181       Default Defined Ports:
182                 tcp 10050
183
184
185       zabbix_port_t
186
187
188
189       Default Defined Ports:
190                 tcp 10051
191

MANAGED FILES

193       The SELinux process type zabbix_t can manage  files  labeled  with  the
194       following file types.  The paths listed are the default paths for these
195       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

275       SELinux requires files to have an extended attribute to define the file
276       type.
277
278       You can see the context of a file using the -Z option to ls
279
280       Policy  governs  the  access  confined  processes  have to these files.
281       SELinux zabbix policy is very flexible allowing users  to  setup  their
282       zabbix processes in as secure a method as possible.
283
284       EQUIVALENCE DIRECTORIES
285
286
287       zabbix  policy  stores  data with multiple different file context types
288       under the /var/lib/zabbix directory.  If you would like  to  store  the
289       data  in a different directory you can use the semanage command to cre‐
290       ate an equivalence mapping.  If you wanted to store this data under the
291       /srv dirctory you would execute the following command:
292
293       semanage fcontext -a -e /var/lib/zabbix /srv/zabbix
294       restorecon -R -v /srv/zabbix
295
296       STANDARD FILE CONTEXT
297
298       SELinux defines the file context types for the zabbix, if you wanted to
299       store files with these types in a diffent paths, you  need  to  execute
300       the  semanage  command  to  sepecify  alternate  labeling  and then use
301       restorecon to put the labels on disk.
302
303       semanage fcontext -a -t zabbixd_var_lib_t '/srv/myzabbix_content(/.*)?'
304       restorecon -R -v /srv/myzabbix_content
305
306       Note: SELinux often uses regular expressions  to  specify  labels  that
307       match multiple files.
308
309       The following file types are defined for zabbix:
310
311
312
313       zabbix_agent_exec_t
314
315       -  Set  files with the zabbix_agent_exec_t type, if you want to transi‐
316       tion an executable to the zabbix_agent_t domain.
317
318
319
320       zabbix_agent_initrc_exec_t
321
322       - Set files with the zabbix_agent_initrc_exec_t type, if  you  want  to
323       transition an executable to the zabbix_agent_initrc_t domain.
324
325
326
327       zabbix_exec_t
328
329       -  Set  files with the zabbix_exec_t type, if you want to transition an
330       executable to the zabbix_t domain.
331
332
333       Paths:
334            /usr/(s)?bin/zabbix_server, /usr/sbin/zabbix_proxy, /usr/sbin/zab‐
335            bix_proxy_mysql,    /usr/sbin/zabbix_proxy_pgsql,   /usr/sbin/zab‐
336            bix_server_mysql,  /usr/sbin/zabbix_server_pgsql,   /usr/sbin/zab‐
337            bix_proxy_sqlite3, /usr/sbin/zabbix_server_sqlite3
338
339
340       zabbix_initrc_exec_t
341
342       -  Set files with the zabbix_initrc_exec_t type, if you want to transi‐
343       tion an executable to the zabbix_initrc_t domain.
344
345
346
347       zabbix_log_t
348
349       - Set files with the zabbix_log_t type, if you want to treat  the  data
350       as zabbix log data, usually stored under the /var/log directory.
351
352
353
354       zabbix_script_exec_t
355
356       -  Set files with the zabbix_script_exec_t type, if you want to transi‐
357       tion an executable to the zabbix_script_t domain.
358
359
360       Paths:
361            /usr/lib/zabbix/externalscripts(/.*)?,      /var/lib/zabbix/exter‐
362            nalscripts(/.*)?
363
364
365       zabbix_tmp_t
366
367       -  Set  files  with  the zabbix_tmp_t type, if you want to store zabbix
368       temporary files in the /tmp directories.
369
370
371
372       zabbix_tmpfs_t
373
374       - Set files with the zabbix_tmpfs_t type, if you want to  store  zabbix
375       files on a tmpfs file system.
376
377
378
379       zabbix_var_lib_t
380
381       -  Set  files  with the zabbix_var_lib_t type, if you want to store the
382       zabbix files under the /var/lib directory.
383
384
385       Paths:
386            /var/lib/zabbix(/.*)?, /var/lib/zabbixsrv(/.*)?
387
388
389       zabbix_var_run_t
390
391       - Set files with the zabbix_var_run_t type, if you want  to  store  the
392       zabbix files under the /run or /var/run directory.
393
394
395
396       zabbixd_var_lib_t
397
398       -  Set  files with the zabbixd_var_lib_t type, if you want to store the
399       zabbixd files under the /var/lib directory.
400
401
402
403       Note: File context can be temporarily modified with the chcon  command.
404       If  you want to permanently change the file context you need to use the
405       semanage fcontext command.  This will modify the SELinux labeling data‐
406       base.  You will need to use restorecon to apply the labels.
407
408

COMMANDS

410       semanage  fcontext  can also be used to manipulate default file context
411       mappings.
412
413       semanage permissive can also be used to manipulate  whether  or  not  a
414       process type is permissive.
415
416       semanage  module can also be used to enable/disable/install/remove pol‐
417       icy modules.
418
419       semanage port can also be used to manipulate the port definitions
420
421       semanage boolean can also be used to manipulate the booleans
422
423
424       system-config-selinux is a GUI tool available to customize SELinux pol‐
425       icy settings.
