Security-Enhanced Linux secures the zabbix processes via flexible mandatory access control.
If you want to allow zabbix to connect to unreserved ports, you must turn on the zabbix_can_network boolean.
setsebool -P zabbix_can_network 1
If you want to allow http daemon to connect to zabbix, you must turn on the httpd_can_connect_zabbix boolean.
setsebool -P httpd_can_connect_zabbix 1
If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd serve for the zabbix_t, you must turn on the authlogin_nsswitch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the zabbix_t, you must turn on the kerberos_enabled boolean.
setsebool -P kerberos_enabled 1
You can see the context of a file using the -Z option to lsP Policy governs the access confined processes have to these files. SELinux zabbix policy is very flexible allowing users to setup their zabbix processes in as secure a method as possible.
The following file types are defined for zabbix:
zabbix_agent_exec_t
- Set files with the zabbix_agent_exec_t type, if you want to transition an executable to the zabbix_agent_t domain.
zabbix_agent_initrc_exec_t
- Set files with the zabbix_agent_initrc_exec_t type, if you want to transition an executable to the zabbix_agent_initrc_t domain.
zabbix_exec_t
- Set files with the zabbix_exec_t type, if you want to transition an executable to the zabbix_t domain.
zabbix_initrc_exec_t
- Set files with the zabbix_initrc_exec_t type, if you want to transition an executable to the zabbix_initrc_t domain.
zabbix_log_t
- Set files with the zabbix_log_t type, if you want to treat the data as zabbix log data, usually stored under the /var/log directory.
zabbix_tmp_t
- Set files with the zabbix_tmp_t type, if you want to store zabbix temporary files in the /tmp directories.
zabbix_tmpfs_t
- Set files with the zabbix_tmpfs_t type, if you want to store zabbix files on a tmpfs file system.
zabbix_var_run_t
- Set files with the zabbix_var_run_t type, if you want to store the zabbix files under the /run directory.
Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.
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 zabbix policy is very flexible allowing users to setup their zabbix processes in as secure a method as possible.
The following port types are defined for zabbix:
Default Defined Ports: tcp 10050
Default Defined Ports: tcp 10051
