6 zabbix_agent_selinux - Security Enhanced Linux Policy for the zab‐
7 bix_agent processes
8
10 Security-Enhanced Linux secures the zabbix_agent processes via flexible
11 mandatory access control.
12 The zabbix_agent processes execute with the zabbix_agent_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep zabbix_agent_t
20
24 The zabbix_agent_t SELinux type can be entered via the zab‐
25 bix_agent_exec_t file type.
26 The default entrypoint paths for the zabbix_agent_t domain are the fol‐
28 lowing:
29 /usr/bin/zabbix_agentd, /usr/sbin/zabbix_agentd
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 zabbix_agent policy is very flexible allowing users to setup their zab‐
40 bix_agent processes in as secure a method as possible.
41 The following process types are defined for zabbix_agent:
43 zabbix_agent_t
45 Note: semanage permissive -a zabbix_agent_t can be used to make the
47 process type zabbix_agent_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required. zab‐
54 bix_agent policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run zabbix_agent with the tight‐
56 est access possible.
57 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.

157 nis_enabled boolean. Disabled by default.
158 setsebool -P nis_enabled 1

164 you must turn on the nscd_use_shm boolean. Disabled by default.
165 setsebool -P nscd_use_shm 1
167 If you want to allow Zabbix to run su/sudo, you must turn on the zab‐
171 bix_run_sudo boolean. Disabled by default.
172 setsebool -P zabbix_run_sudo 1
174
178 SELinux defines port types to represent TCP and UDP ports.
179 You can see the types associated with a port by using the following
181 command:
182 semanage port -l
184 Policy governs the access confined processes have to these ports.
187 SELinux zabbix_agent policy is very flexible allowing users to setup
188 their zabbix_agent processes in as secure a method as possible.
189 The following port types are defined for zabbix_agent:
191 zabbix_agent_port_t
194 Default Defined Ports:
198 tcp 10050
199
201 The SELinux process type zabbix_agent_t can manage files labeled with
202 the following file types. The paths listed are the default paths for
203 these file types. Note the processes UID still need to have DAC per‐
204 missions.

269 SELinux requires files to have an extended attribute to define the file
270 type.
271 You can see the context of a file using the -Z option to ls
273 Policy governs the access confined processes have to these files.
275 SELinux zabbix_agent policy is very flexible allowing users to setup
276 their zabbix_agent processes in as secure a method as possible.
277 The following file types are defined for zabbix_agent:
279 zabbix_agent_exec_t
283 - Set files with the zabbix_agent_exec_t type, if you want to transi‐
285 tion an executable to the zabbix_agent_t domain.
286 Paths:
289 /usr/bin/zabbix_agentd, /usr/sbin/zabbix_agentd
290 zabbix_agent_initrc_exec_t
293 - Set files with the zabbix_agent_initrc_exec_t type, if you want to
295 transition an executable to the zabbix_agent_initrc_t domain.
296 Note: File context can be temporarily modified with the chcon command.
300 If you want to permanently change the file context you need to use the
301 semanage fcontext command. This will modify the SELinux labeling data‐
302 base. You will need to use restorecon to apply the labels.
303
306 semanage fcontext can also be used to manipulate default file context
307 mappings.
308 semanage permissive can also be used to manipulate whether or not a
310 process type is permissive.
311 semanage module can also be used to enable/disable/install/remove pol‐
313 icy modules.
314 semanage port can also be used to manipulate the port definitions
316 semanage boolean can also be used to manipulate the booleans
318 system-config-selinux is a GUI tool available to customize SELinux pol‐
321 icy settings.
