To secure the communication between {beatname_uc} and Elasticsearch, you can use
|
||
|
|
HTTPS and basic authentication. Basic authentication for Elasticsearch is
|
||
|
|
available when you enable {security} (see
|
||
|
|
{securitydoc}/xpack-security.html[Securing the {stack}] and <<securing-beats>>).
|
||
|
|
If you aren't using {security}, you can use a web proxy instead.
|
||
|
|
|
||
|
|
Here is a sample configuration:
|
||
|
|
|
||
|
|
["source","yaml",subs="attributes,callouts"]
|
||
|
|
----------------------------------------------------------------------
|
||
|
|
output.elasticsearch:
|
||
|
|
username: {beatname_lc} <1>
|
||
|
|
password: verysecret <2>
|
||
|
|
protocol: https <3>
|
||
|
|
hosts: ["elasticsearch.example.com:9200"] <4>
|
||
|
|
----------------------------------------------------------------------
|
||
|
|
<1> The username to use for authenticating to Elasticsearch.
|
||
|
|
<2> The password to use for authenticating to Elasticsearch.
|
||
|
|
<3> This setting enables the HTTPS protocol.
|
||
|
|
<4> The IP and port of the Elasticsearch nodes.
|
||
|
|
|
||
|
|
TIP: To obfuscate passwords and other sensitive settings, use the
|
||
|
|
<<keystore,secrets keystore>>.

{beatname_uc} verifies the validity of the server certificates and only accepts trusted
|
||
|
|
certificates. Creating a correct SSL/TLS infrastructure is outside the scope of
|
||
|
|
this document.
|
||
|
|
|
||
|
|
By default {beatname_uc} uses the list of trusted certificate authorities from the
|
||
|
|
operating system where {beatname_uc} is running. You can configure {beatname_uc} to use a specific list of
|
||
|
|
CA certificates instead of the list from the OS. You can also configure it to use client authentication
|
||
|
|
by specifying the certificate and key to use when the server requires the Beat to authenticate. Here is an example
|
||
|
|
configuration:
|
||
|
|
|
||
|
|
["source","yaml",subs="attributes,callouts"]
|
||
|
|
----------------------------------------------------------------------
|
||
|
|
output.elasticsearch:
|
||
|
|
username: {beatname_lc}
|
||
|
|
password: verysecret
|
||
|
|
protocol: https
|
||
|
|
hosts: ["elasticsearch.example.com:9200"]
|
||
|
|
ssl.certificate_authorities: <1>
|
||
|
|
- /etc/pki/my_root_ca.pem
|
||
|
|
- /etc/pki/my_other_ca.pem
|
||
|
|
ssl.certificate: "/etc/pki/client.pem" <2>
|
||
|
|
ssl.key: "/etc/pki/key.pem" <3>
|
||
|
|
----------------------------------------------------------------------
|
||
|
|
<1> The list of CA certificates to trust
|
||
|
|
<2> The path to the certificate for SSL client authentication
|
||
|
|
<3> The client certificate key
|
||
|
|
|
||
|
|
NOTE: For any given connection, the SSL/TLS certificates must have a subject
|
||
|
|
that matches the value specified for `hosts`, or the SSL handshake fails.
|
||
|
|
For example, if you specify `hosts: ["foobar:9200"]`, the certificate MUST
|
||
|
|
include `foobar` in the subject (`CN=foobar`) or as a subject alternative name
|
||
|
|
(SAN). Make sure the hostname resolves to the correct IP address. If no DNS is available, then
|
||
|
|
you can associate the IP address with your hostname in `/etc/hosts`
|
||
|
|
(on Unix) or `C:\Windows\System32\drivers\etc\hosts` (on Windows).
