6 zabbix_selinux - Security Enhanced Linux Policy for the zabbix pro‐
7 cesses
8
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
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/bin/zabbix_server, /usr/sbin/zabbix_proxy, /usr/sbin/zab‐
30 bix_server, /usr/sbin/zabbix_proxy_mysql, /usr/sbin/zabbix_proxy_pgsql,
31 /usr/sbin/zabbix_server_mysql, /usr/sbin/zabbix_server_pgsql,
32 /usr/sbin/zabbix_proxy_sqlite3, /usr/sbin/zabbix_server_sqlite3
33
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_t, zabbix_agent_t, zabbix_script_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
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.
58
59
60
61 If you want to determine whether zabbix can connect to all TCP ports,
62 you must turn on the zabbix_can_network boolean. Disabled by default.
63
64 setsebool -P zabbix_can_network 1
65
66
67
68 If you want to allow Zabbix to run su/sudo, you must turn on the zab‐
69 bix_run_sudo boolean. Disabled by default.
70
71 setsebool -P zabbix_run_sudo 1
72
73
74
75 If you want to allow users to resolve user passwd entries directly from
76 ldap rather then using a sssd server, you must turn on the authlo‐
77 gin_nsswitch_use_ldap boolean. Disabled by default.
78
79 setsebool -P authlogin_nsswitch_use_ldap 1
80
81
82
83 If you want to allow all domains to execute in fips_mode, you must turn
84 on the fips_mode boolean. Enabled by default.
85
86 setsebool -P fips_mode 1
87
88
89
90 If you want to allow confined applications to run with kerberos, you
91 must turn on the kerberos_enabled boolean. Enabled by default.
92
93 setsebool -P kerberos_enabled 1
94
95
96
97 If you want to allow system to run with NIS, you must turn on the
98 nis_enabled boolean. Disabled by default.
99
100 setsebool -P nis_enabled 1
101
102
103
104 If you want to allow confined applications to use nscd shared memory,
105 you must turn on the nscd_use_shm boolean. Disabled by default.
106
107 setsebool -P nscd_use_shm 1
108
109
110
112 SELinux defines port types to represent TCP and UDP ports.
113
114 You can see the types associated with a port by using the following
115 command:
116
117 semanage port -l
118
119
120 Policy governs the access confined processes have to these ports.
121 SELinux zabbix policy is very flexible allowing users to setup their
122 zabbix processes in as secure a method as possible.
123
124 The following port types are defined for zabbix:
125
126
127 zabbix_agent_port_t
128
129
130
131 Default Defined Ports:
132 tcp 10050
133
134
135 zabbix_port_t
136
137
138
139 Default Defined Ports:
140 tcp 10051
141
143 The SELinux process type zabbix_t can manage files labeled with the
144 following file types. The paths listed are the default paths for these
145 file types. Note the processes UID still need to have DAC permissions.

218 SELinux requires files to have an extended attribute to define the file
219 type.
220
221 You can see the context of a file using the -Z option to ls
222
223 Policy governs the access confined processes have to these files.
224 SELinux zabbix policy is very flexible allowing users to setup their
225 zabbix processes in as secure a method as possible.
226
227 EQUIVALENCE DIRECTORIES
228
229
230 zabbix policy stores data with multiple different file context types
231 under the /var/lib/zabbix directory. If you would like to store the
232 data in a different directory you can use the semanage command to cre‐
233 ate an equivalence mapping. If you wanted to store this data under the
234 /srv dirctory you would execute the following command:
235
236 semanage fcontext -a -e /var/lib/zabbix /srv/zabbix
237 restorecon -R -v /srv/zabbix
238
239 STANDARD FILE CONTEXT
240
241 SELinux defines the file context types for the zabbix, if you wanted to
242 store files with these types in a diffent paths, you need to execute
243 the semanage command to sepecify alternate labeling and then use
244 restorecon to put the labels on disk.
245
246 semanage fcontext -a -t zabbix_var_run_t '/srv/myzabbix_content(/.*)?'
247 restorecon -R -v /srv/myzabbix_content
248
249 Note: SELinux often uses regular expressions to specify labels that
250 match multiple files.
251
252 The following file types are defined for zabbix:
253
254
255
256 zabbix_agent_exec_t
257

259 tion an executable to the zabbix_agent_t domain.

290 tion an executable to the zabbix_initrc_t domain.
291
292
293
294 zabbix_log_t
295

298
299
300
301 zabbix_script_exec_t

309 nalscripts(/.*)?
310
311
312 zabbix_tmp_t

315 temporary files in the /tmp directories.
316
317

320
321 - Set files with the zabbix_tmpfs_t type, if you want to store zabbix

346 zabbixd files under the /var/lib directory.
347
348
349
350 Note: File context can be temporarily modified with the chcon command.
351 If you want to permanently change the file context you need to use the
352 semanage fcontext command. This will modify the SELinux labeling data‐
353 base. You will need to use restorecon to apply the labels.
354
355
357 semanage fcontext can also be used to manipulate default file context
358 mappings.
359
360 semanage permissive can also be used to manipulate whether or not a
361 process type is permissive.
362
363 semanage module can also be used to enable/disable/install/remove pol‐
364 icy modules.
365
366 semanage port can also be used to manipulate the port definitions
367
368 semanage boolean can also be used to manipulate the booleans
369

371 system-config-selinux is a GUI tool available to customize SELinux pol‐
372 icy settings.
