Configuring CA Bundle with Elastalert > SearchGuard

Hello, I am trying to setup Elastalert, following this guide:

And am running into an issue:

use_ssl: True
verify_certs: True

``

I appreciate this isn’t your software, but I was curious as to if you had any advice?

It looks like it doesn’t really handle TLS certs / keys, we have modified the elastalert code in order to get around this.

You can close this :slight_smile:

I appreciate this isn’t your software, but I was curious as to if you had any advice?

Can you publish your code changes/sulution (or even better commit them back to the elastalert project?)

I appreciate this isn’t your software, but I was curious as to if you had any advice?

I will look at doing that tomorrow, it looks like a similar pull request is already in their repo waiting for a merge.

I will check with my boss and then get back to you tomorrow.

Now, the ca-bundle I am providing is exactly the same as what is configured on the Elastic master I am trying to talk to:

md5sum /etc/elastalert/ca-bundle.pem

b72ec81db7ee1831232020df0a807743 /etc/elastalert/ca-bundle.pem

md5sum /etc/elasticsearch/elastic-master-01x/ca-bundle.pem
b72ec81db7ee1831232020df0a807743

``

The configuration I have inside ES is:

searchguard.ssl.transport.pemkey_filepath: elastic-nodes-key.pkcs8
searchguard.ssl.transport.pemcert_filepath: elastic-master-01.x-x.com.pem
searchguard.ssl.transport.pemtrustedcas_filepath: ca-bundle.pem

And then the Elastalert config:

es_port: 9200

es_username: x
es_password: x
use_ssl: True
verify_certs: True

You can now update that documentation,

Elastalert now accepts, client cert and key.

The following works with me for searchguard.

es_host: elastic-master-01.x-x.com
es_port: 9200

es_username: x
es_password: x
use_ssl: True
verify_certs: True
client_cert: /etc/elastalert/elastic-admin.pem
client_key: /etc/elastalert/elastic-admin-key.pem
ca_certs: /etc/elastalert/ca-bundle.pem

I will look at doing that tomorrow, it looks like a similar pull request is already in their repo waiting for a merge.

I will check with my boss and then get back to you tomorrow.

Can you publish your code changes/sulution (or even better commit them back to the elastalert project?)

It looks like it doesn’t really handle TLS certs / keys, we have modified the elastalert code in order to get around this.

You can close this :slight_smile:

Now, the ca-bundle I am providing is exactly the same as what is configured on the Elastic master I am trying to talk to:

md5sum /etc/elasticsearch/elastic-master-01x/ca-bundle.pem
b72ec81db7ee1831232020df0a807743

md5sum /etc/elastalert/ca-bundle.pem
b72ec81db7ee1831232020df0a807743 /etc/elastalert/ca-bundle.pem

The configuration I have inside ES is:

searchguard.ssl.transport.pemkey_filepath: elastic-nodes-key.pkcs8
searchguard.ssl.transport.pemcert_filepath: elastic-master-01.x-x.com.pem
searchguard.ssl.transport.pemtrustedcas_filepath: ca-bundle.pem
searchguard.ssl.transport.pemkey_password: x
searchguard.ssl.http.enabled: true
searchguard.ssl.http.pemkey_filepath: elastic-nodes-key.pkcs8
searchguard.ssl.http.pemcert_filepath: elastic-master-01.x-x.com.pem
searchguard.ssl.http.pemtrustedcas_filepath: ca-bundle.pem
searchguard.ssl.http.pemkey_password: x
searchguard.authcz.admin_dn:

network.publish_host: elastic-master-01.x-x.com

searchguard.ssl.transport.enforce_hostname_verification: true

And then the Elastalert config:

es_host: elastic-master-01.x-x.com

es_port: 9200

es_username: x
es_password: x
use_ssl: True
verify_certs: True
ca_certs: /etc/elastalert/ca-bundle.pem

I appreciate this isn’t your software, but I was curious as to if you had any advice?
