<p>You can use SSL mutual authentication to secure connections between APM Server and Logstash. This ensures that
APM Server sends encrypted data to trusted Logstash servers only, and that the Logstash server receives data from
trusted APM Server clients only.</p>
<p>To use SSL mutual authentication:</p>
<div class="olist orderedlist">
<ol class="orderedlist">
<li class="listitem">
<p>Create a certificate authority (CA) and use it to sign the certificates that you plan to use for
APM Server and Logstash. Creating a correct SSL/TLS infrastructure is outside the scope of this
document. There are many online resources available that describe how to create certificates.</p>
<div class="tip admon">
<div class="icon"></div>
<div class="admon_content">
<p>If you are using security features, you can use the
<a href="/guide/en/elasticsearch/reference/7.15/certutil.html" class="ulink" target="_top">elasticsearch-certutil tool</a> to generate certificates.</p>
</div>
</div>
</li>
<li class="listitem">
<p>Configure APM Server to use SSL. In the <code class="literal">apm-server.yml</code> config file, specify the following settings under
<code class="literal">ssl</code>:</p>
<div class="ulist itemizedlist">
<ul class="itemizedlist">
<li class="listitem">
<code class="literal">certificate_authorities</code>: Configures APM Server to trust any certificates signed by the specified CA. If
<code class="literal">certificate_authorities</code> is empty or not set, the trusted certificate authorities of the host system are used.
</li>
<li class="listitem">
<p><code class="literal">certificate</code> and <code class="literal">key</code>: Specifies the certificate and key that APM Server uses to authenticate with
Logstash.</p>
<p>For example:</p>
<div class="pre_wrapper lang-yaml">
<div class="console_code_copy" title="Copy to clipboard"></div>
<pre class="programlisting prettyprint lang-yaml">output.logstash:
hosts: ["logs.mycompany.com:5044"]
ssl.certificate_authorities: ["/etc/ca.crt"]
ssl.certificate: "/etc/client.crt"
ssl.key: "/etc/client.key"</pre>
</div>
<p>For more information about these configuration options, see <a class="xref" href="configuration-ssl.html" title="SSL output settings">SSL output settings</a>.</p>
</li>
</ul>
</div>
</li>
<li class="listitem">
<p>Configure Logstash to use SSL. In the Logstash config file, specify the following settings for the <a href="/guide/en/logstash/current/plugins-inputs-beats.html" class="ulink" target="_top">Beats input plugin for Logstash</a>:</p>
<div class="ulist itemizedlist">
<ul class="itemizedlist">
<li class="listitem">
<code class="literal">ssl</code>: When set to true, enables Logstash to use SSL/TLS.
</li>
<li class="listitem">
<code class="literal">ssl_certificate_authorities</code>: Configures Logstash to trust any certificates signed by the specified CA.
</li>
<li class="listitem">
<code class="literal">ssl_certificate</code> and <code class="literal">ssl_key</code>: Specify the certificate and key that Logstash uses to authenticate with the client.
</li>
<li class="listitem">
<p><code class="literal">ssl_verify_mode</code>: Specifies whether the Logstash server verifies the client certificate against the CA. You
need to specify either <code class="literal">peer</code> or <code class="literal">force_peer</code> to make the server ask for the certificate and validate it. If you
specify <code class="literal">force_peer</code>, and APM Server doesn’t provide a certificate, the Logstash connection will be closed. If you choose not to use <a href="/guide/en/elasticsearch/reference/7.15/certutil.html" class="ulink" target="_top">certutil</a>, the certificates that you obtain must allow for both <code class="literal">clientAuth</code> and <code class="literal">serverAuth</code> if the extended key usage extension is present.</p>
<p>For example:</p>
<div class="pre_wrapper lang-json">
<div class="console_code_copy" title="Copy to clipboard"></div>
<pre class="programlisting prettyprint lang-json">input {
beats {
port => 5044
ssl => true
ssl_certificate_authorities => ["/etc/ca.crt"]
ssl_certificate => "/etc/server.crt"
ssl_key => "/etc/server.key"
ssl_verify_mode => "force_peer"
}
}</pre>
</div>
<p>For more information about these options, see the
<a href="/guide/en/logstash/current/plugins-inputs-beats.html" class="ulink" target="_top">documentation for the Beats input plugin</a>.</p>
</li>
</ul>
</div>
</li>
</ol>
</div>
<div class="position-relative"><h3><a id="testing-ssl-logstash"></a>Validate the Logstash server’s certificate</h3><a class="edit_me" rel="nofollow" title="Edit this page on GitHub" href="https://github.com/elastic/apm-server/edit/7.15/docs/copied-from-beats/docs/shared-ssl-logstash-config.asciidoc">edit</a></div>
<p>Before running APM Server, you should validate the Logstash server’s certificate. You can use <code class="literal">curl</code> to validate the certificate even though the protocol used to communicate with Logstash is not based on HTTP. For example:</p>
<div class="pre_wrapper lang-shell">
<div class="console_code_copy" title="Copy to clipboard"></div>
<pre class="programlisting prettyprint lang-shell">curl -v --cacert ca.crt https://logs.mycompany.com:5044</pre>
</div>
<p>If the test is successful, you’ll receive an empty response error:</p>
<div class="pre_wrapper lang-shell">
<div class="console_code_copy" title="Copy to clipboard"></div>
<pre class="programlisting prettyprint lang-shell">* Rebuilt URL to: https://logs.mycompany.com:5044/
* Trying 192.168.99.100...
* Connected to logs.mycompany.com (192.168.99.100) port 5044 (#0)
* TLS 1.2 connection using TLS_DHE_RSA_WITH_AES_256_CBC_SHA
* Server certificate: logs.mycompany.com
* Server certificate: mycompany.com
> GET / HTTP/1.1
> Host: logs.mycompany.com:5044
> User-Agent: curl/7.43.0
> Accept: */*
>
* Empty reply from server
* Connection #0 to host logs.mycompany.com left intact
curl: (52) Empty reply from server</pre>
</div>
<p>The following example uses the IP address rather than the hostname to validate the certificate:</p>
<div class="pre_wrapper lang-shell">
<div class="console_code_copy" title="Copy to clipboard"></div>
<pre class="programlisting prettyprint lang-shell">curl -v --cacert ca.crt https://192.168.99.100:5044</pre>
</div>
<p>Validation for this test fails because the certificate is not valid for the specified IP address. It’s only valid for the <code class="literal">logs.mycompany.com</code>, the hostname that appears in the Subject field of the certificate.</p>
