zabbix_selinux(8) zabbix SELinux Policy documentation zabbix_selinux(8)NAMEzabbix_selinux - Security Enhanced Linux Policy for the zabbix pro‐
cesses
DESCRIPTION
Security-Enhanced Linux secures the zabbix processes via flexible
mandatory access control.
BOOLEANS
SELinux policy is customizable based on least access required. zabbix
policy is extremely flexible and has several booleans that allow you to
manipulate the policy and run zabbix with the tightest access possible.
If you want to allow zabbix to connect to unreserved port, 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 zabbi, you must turn on
the httpd_can_connect_zabbix boolean.
setsebool -P httpd_can_connect_zabbix 1
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the zab‐
bix_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 allow_kerberos boolean.
setsebool -P allow_kerberos 1
If you want to allow system to run with NI for the zabbix_t, you must
turn on the allow_ypbind boolean.
setsebool -P allow_ypbind 1
FILE CONTEXTS
SELinux requires files to have an extended attribute to define the file
type.
You can see the context of a file using the -Z option to ls
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 transi‐
tion 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.
Paths:
/usr/sbin/zabbix_server_pgsql, /usr/sbin/zabbix_server_sqlite3,
/usr/sbin/zabbix_server_mysql, /usr/sbin/zabbix_server
zabbix_initrc_exec_t
- Set files with the zabbix_initrc_exec_t type, if you want to transi‐
tion an executable to the zabbix_initrc_t domain.
Paths:
/etc/rc.d/init.d/zabbix-server, /etc/rc.d/init.d/zabbix
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 permanantly change the file context you need to use the
semanage fcontext command. This will modify the SELinux labeling data‐
base. You will need to use restorecon to apply the labels.
PORT TYPES
SELinux defines port types to represent TCP and UDP ports.
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:
zabbix_agent_port_t
Default Defined Ports:
tcp 10050
zabbix_port_t
Default Defined Ports:
tcp 10051
PROCESS TYPES
SELinux defines process types (domains) for each process running on the
system
You can see the context of a process using the -Z option to ps
Policy governs the access confined processes have to files. SELinux
zabbix policy is very flexible allowing users to setup their zabbix
processes in as secure a method as possible.
The following process types are defined for zabbix:
zabbix_agent_t, zabbix_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process
type permissive. Permissive process types are not denied access by
SELinux. AVC messages will still be generated.
COMMANDS
semanage fcontext can also be used to manipulate default file context
mappings.
semanage permissive can also be used to manipulate whether or not a
process type is permissive.
semanage module can also be used to enable/disable/install/remove pol‐
icy modules.
semanage port can also be used to manipulate the port definitions
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
