Secure Elasticsearch and Kibana with an Nginx HTTP Proxy

Elasticsearch provides a great HTTP API where applications can write to and read from in high performance environments. One of our customers sponsored a feature for Icinga 2 which writes events and performance data metrics to Elasticsearch. This will hit v2.8 later this year.

We’re also concerned about security, and have been looking into security mechanisms such as basic auth or TLS. Unfortunately this isn’t included in the Open Source stack.

 

Why should you care about securing Elasticsearch and Kibana?

Modern infrastructure deployments commonly require Elasticsearch listening on an external interface and answering HTTP requests. Earlier this year we’ve learned about ransomware attacks on MongoDB and Elasticsearch too.

During development I’ve found this API call – just clear everything inside the database.

[root@icinga2-elastic ~]# curl -X DELETE http://localhost:9200/_all
{"acknowledged":true}

I don’t want any user to run this command from anywhere. You can disable this by setting “action.destructive_requires_name” to “true” inside the configuration, but it is not the default.

A similar thing is that you can read and write anything without any access rules in place, no matter if querying Elasticsearch or Kibana directly.

 

Firewall and Network Segments

A possible solution is to limit the network transport to only allowed hosts via firewall rules and so on. If your Elasticsearch cluster is running on a dedicated VLAN, you would need to allow the Icinga 2 monitoring host to write data into http://elasticsearch.yourdomain:9200 – anyone on that machine could still read/write without any security mechanism in place.

 

HTTP Proxy with Nginx

Start with the plain proxy pass configuration and forward http://localhosT:9200 to your external interface (192.168.33.7 in this example).

# MANAGED BY PUPPET
server {
  listen       192.168.33.7:9200;
  server_name  elasticsearch.vagrant-demo.icinga.com;

  index  index.html index.htm index.php;

  access_log            /var/log/nginx/ssl-elasticsearch.vagrant-demo.icinga.com.access.log combined;
  error_log             /var/log/nginx/ssl-elasticsearch.vagrant-demo.icinga.com.error.log;

  location / {
    proxy_pass            http://localhost:9200;
    proxy_read_timeout    90;
    proxy_connect_timeout 90;
    proxy_set_header      Host $host;
    proxy_set_header      X-Real-IP $remote_addr;
    proxy_set_header      X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header      Proxy "";
  }
}

Restart Nginx and test the connection from the external interface.

# systemctl restart nginx

# curl -v http://192.168.33.7:9200

Once this is working, proceed with adding basic auth and TLS.

 

HTTP Proxy with Basic Auth

This leverages the access level to authenticated users only. Best is to manage the basic auth users file with Puppet, Ansible, etc. – similar to how you manage your Nginx configuration. Our consultants use that method on a regular basis, and provided me with some examples for Nginx. You could do the same for Apache – I would guess that is a matter of taste and performance here.

Generate a username/password combination e.g. using the htpasswd CLI command.

htpasswd -c /etc/nginx/elasticsearch.passwd icinga

Specify the basic auth message and the file which contains the basic auth users.

    auth_basic                "Elasticsearch auth";
    auth_basic_user_file      "/etc/nginx/elasticsearch.passwd";

Restart Nginx and connect to the external interface.

# systemctl restart nginx

# curl -v -u icinga:icinga http://192.168.33.7:9200

 

HTTP Proxy with TLS

The Elasticsearch HTTP API does not support TLS out-of-the-box. You need to enforce HTTPS via HTTP Proxy, enable ssl and set up the required certificates.

Enforce the listen address to SSL only. That way http won’t work.

  listen       192.168.33.7:9200 ssl;

Enable SSL, specify the certificate paths on disk, use TLSv1 and above and optionally secure the used ciphers.

  ssl on;

  ssl_certificate           /etc/nginx/certs/icinga2-elastic.crt;
  ssl_certificate_key       /etc/nginx/certs/icinga2-elastic.key;
  ssl_session_cache         shared:SSL:10m;
  ssl_session_timeout       5m;
  ssl_protocols             TLSv1 TLSv1.1 TLSv1.2;
  ssl_ciphers               ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA:ECDHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES256-SHA:ECDHE-ECDSA-DES-CBC3-SHA:ECDHE-RSA-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:DES-CBC3-SHA:!DSS;
  ssl_prefer_server_ciphers on;
  ssl_trusted_certificate   /etc/nginx/certs/ca.crt;

Restart Nginx and connect to the external interface on https. Note: Host verification is disabled in this example.

# systemctl restart nginx

# curl -v -k -u icinga:icinga https://192.168.33.7:9200

 

Combine HTTP Proxy, TLS and Basic Auth

A complete configuration example could look like this:

vim /etc/nginx/sites-enabled/elasticsearch.vagrant-demo.icinga.com.conf

# MANAGED BY PUPPET
server {
  listen       192.168.33.7:9200 ssl;
  server_name  elasticsearch.vagrant-demo.icinga.com;

  ssl on;

  ssl_certificate           /etc/nginx/certs/icinga2-elastic.crt;
  ssl_certificate_key       /etc/nginx/certs/icinga2-elastic.key;
  ssl_session_cache         shared:SSL:10m;
  ssl_session_timeout       5m;
  ssl_protocols             TLSv1 TLSv1.1 TLSv1.2;
  ssl_ciphers               ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA:ECDHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES256-SHA:ECDHE-ECDSA-DES-CBC3-SHA:ECDHE-RSA-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:DES-CBC3-SHA:!DSS;
  ssl_prefer_server_ciphers on;
  ssl_trusted_certificate   /etc/nginx/certs/ca.crt;

  uth_basic                "Elasticsearch auth";
  auth_basic_user_file      "/etc/nginx/elasticsearch.passwd";
  index  index.html index.htm index.php;

  access_log            /var/log/nginx/ssl-elasticsearch.vagrant-demo.icinga.com.access.log combined;
  error_log             /var/log/nginx/ssl-elasticsearch.vagrant-demo.icinga.com.error.log;

  location / {
    proxy_pass            http://localhost:9200;
    proxy_read_timeout    90;
    proxy_connect_timeout 90;
    proxy_set_header      Host $host;
    proxy_set_header      X-Real-IP $remote_addr;
    proxy_set_header      X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header      Proxy "";
  }
}

The following example query does not verify the offered host certificate. In case you configure the ElasticWriter feature in Icinga 2 v2.8, you’ll find the options to specify certificates for TLS handshake verification.

$ curl -v -k -u icinga:icinga https://192.168.33.7:9200

Conclusion

Secure data transfer from your monitoring instances to Elasticsearch is mandatory. Basic access control via basic auth should also be implemented. All of this is possible with the help of a dedicated HTTP Proxy host. Fine granular access control for specific HTTP requests is available in the commercial Shield package or variants. While securing Elasticsearch, also look into Kibana which runs on port 5601.

Since we’ve used the Icinga Vagrant boxes as a development playground, I’ve added Nginx as HTTP Proxy inside the icinga2x-elastic box. This provisions the required basic auth and TLS settings and offers to write data on https://192.168.33.7:9200 (icinga/icinga). The same applies for Kibana. The examples above can be replayed too.

If you want to learn more on this topic, make sure to join our Elastic Stack training sessions or kindly invite one of our consultants for a hands-on workshop. Hint: There is an Elastic Stack workshop at OSMC too 🙂

Manage Elasticsearch, Kibana & icingabeat with Puppet

A while back I’ve already looked into the Elastic Stack 5 Beta release and the beats integration. Time flies and the stable release is here. Blerim announced the icingabeat 1.0.0 release last week, and so I was looking into a smooth integration into a Vagrant box here.

The provisioner uses Puppet, which Puppet modules could be used here? I’m always looking for actively maintained modules, best by upstream projects which share the joy of automated setups of their tools with their community.

 

Elastic and Kibana Puppet Module

The Elastic developers started writing their own Puppet module for Kibana 5.x. Previously I’ve used community modules such as puppet-kibana4 or puppet-kibana5. puppet-elasticsearch already supports 5.x for a while, that works like a charm.

Simple example for a low memory Elasticsearch setup:

class { 'elasticsearch':
  manage_repo  => true,
  repo_version => '5.x',
  java_install => false,
  jvm_options => [
    '-Xms256m',
    '-Xmx256m'
  ],
  require => Class['java']
} ->
elasticsearch::instance { 'elastic-es':
  config => {
    'cluster.name' => 'elastic',
    'network.host' => '127.0.0.1'
  }
}

Note: jvm_options was released in 5.0.0.

 

Default index pattern

If you do not define any default index pattern, Kibana greets you with a fancy message to do so (and I have to admit – i still need an Elastic Stack training to fully understand why). I wanted to automate that, so that Vagrant box users don’t need to care about it. There are several threads around which describe the deployment by sending a PUT request to the Elasticsearch backend.

I’m using a small script here which waits until Elasticsearch is started. If you don’t do that, the REST API calls will fail later on. This is also required for specifying index patterns and importing dashboards. A Puppet exec timeout won’t do the trick here, because we’ll have to loop and check again if the service is available.

$ cat/usr/local/bin/kibana-setup
#!/bin/bash

ES_URL="http://localhost:9200"
TIMEOUT=300

START=$(date +%s)

echo -e "Restart elasticsearch instance"
systemctl restart elasticsearch-elastic-es

echo -e "Checking whether Elasticsearch is listening at $ES_URL"
until $(curl --output /dev/null --silent $ES_URL); do
  NOW=$(date +%s)
  REAL_TIMEOUT=$(( START + TIMEOUT ))
  if [[ "$NOW" -gt "$REAL_TIMEOUT" ]]; then
    echo "Cannot reach Elasticsearch at $ES_URL. Timeout reached."
    exit 1
  fi
  printf '.'
  sleep 1
done

If you would want to specify the default index pattern i.e. for an installed filebeat service, you could something like this:

ES_INDEX_URL="$ES_URL/.kibana/index-pattern/filebeat"
ES_DEFAULT_INDEX_URL="$ES_URL/.kibana/config/5.2.2" #hardcoded program version

curl -XPUT $ES_INDEX_URL -d '{ "title":"filebeat", "timeFieldName":"@timestamp" }'
curl -XPUT $ES_DEFAULT_INDEX_URL -d '{ "defaultIndex":"filebeat" }'

One problem arises: The configuration is stored by Kibana program version. There is no symlink like ‘latest’, but you’ll need to specify ‘.kibana/config/5.2.2’ to make it work. There is a certain requirement for pinning the Kibana version, or finding a programatic way to automatically determine the version.

 

Kibana Version in Puppet

Fortunately the Puppet module allows for specifying a version. Turns out, the class validation doesn’t support package revision known from rpm (“5.2.2-1”). Open source is awesome – you manage to patch it, apply tests and after review your contributed patch gets merged upstream.

Example for Kibana with a pinned package version:

$kibanaVersion = '5.2.2'

class { 'kibana':
  ensure => "$kibanaVersion-1",
  config => {
    'server.port' => 5601,
    'server.host' => '0.0.0.0',
    'kibana.index' => '.kibana',
    'kibana.defaultAppId' => 'discover',
    'logging.silent'               => false,
    'logging.quiet'                => false,
    'logging.verbose'              => false,
    'logging.events'               => "{ log: ['info', 'warning', 'error', 'fatal'], response: '*', error: '*' }",
    'elasticsearch.requestTimeout' => 500000,
  },
  require => Class['java']
}
->
file { 'kibana-setup':
  name => '/usr/local/bin/kibana-setup',
  owner => root,
  group => root,
  mode => '0755',
  source => "puppet:////vagrant/files/usr/local/bin/kibana-setup",
}
->
exec { 'finish-kibana-setup':
  path => '/bin:/usr/bin:/sbin:/usr/sbin',
  command => "/usr/local/bin/kibana-setup",
  timeout => 3600
}

 

Icingabeat integration

That’s fairly easy, just install the rpm and put a slightly modified icingabeat.yml there.

$icingabeatVersion = '1.0.0'

yum::install { 'icingabeat':
  ensure => present,
  source => "https://github.com/Icinga/icingabeat/releases/download/v$icingabeatVersion/icingabeat-$icingabeatVersion-x86_64.rpm"
}->
file { '/etc/icingabeat/icingabeat.yml':
  source    => 'puppet:////vagrant/files/etc/icingabeat/icingabeat.yml',
}->
service { 'icingabeat':
  ensure => running
}

I’ve also found the puppet-archive module from Voxpupuli which allows to download and extract the required Kibana dashboards from icingabeat. The import then requires that Elasticsearch is up and running (referencing the kibana setup script again). You’ll notice the reference to the pinned Kibana version for setting the default index pattern via exec resource.

# https://github.com/icinga/icingabeat#dashboards
archive { '/tmp/icingabeat-dashboards.zip':
  ensure => present,
  extract => true,
  extract_path => '/tmp',
  source => "https://github.com/Icinga/icingabeat/releases/download/v$icingabeatVersion/icingabeat-dashboards-$icingabeatVersion.zip",
  checksum => 'b6de2adf2f10b77bd4e7f9a7fab36b44ed92fa03',
  checksum_type => 'sha1',
  creates => "/tmp/icingabeat-dashboards-$icingabeatVersion",
  cleanup => true,
  require => Package['unzip']
}->
exec { 'icingabeat-kibana-dashboards':
  path => '/bin:/usr/bin:/sbin:/usr/sbin',
  command => "/usr/share/icingabeat/scripts/import_dashboards -dir /tmp/icingabeat-dashboards-$icingabeatVersion -es http://127.0.0.1:9200",
  require => Exec['finish-kibana-setup']
}->
exec { 'icingabeat-kibana-default-index-pattern':
  path => '/bin:/usr/bin:/sbin:/usr/sbin',
  command => "curl -XPUT http://127.0.0.1:9200/.kibana/config/$kibanaVersion -d '{ \"defaultIndex\":\"icingabeat-*\" }'",
}

The Puppet code is the first working draft, I plan to refactor the upstream code. Look how fancy 🙂

Conclusion

Managing your Elastic Stack setup with Puppet really has become a breeze. I haven’t tackled the many plugins and dashboards available, there’s so much more to explore. Once you’ve integrated icingabeat into your devops stack, how would you build your own dashboards to correlate operations maintenance with Icinga alerts? 🙂

If you’re interested in learning more about Elastic and the awesome Beats integrations, make sure to join OSDC 2017. Monica Sarbu joins us with her talk on “Collecting the right data to monitor your infrastructure”.

PS: Test-drive the integration, finished today 🙂

On Tour with Icinga 2: San Francisco

The best thing about travelling? Definitely meeting people! My four colleagues and I had the chance to be guests at Pivotal and Slack in San Francisco.

Our group used the trip to Elastic{ON}17 in San Francisco as an opportunity to meet with other people who are active in the Icinga universe. Our first stop was at Pivotal who were kind enough to host our Icinga Camp at their office.

After a warm welcome at Pivotal, our keynote speaker Blerim Sheqa started our Icinga Camp by welcoming our guests. His talk provided insights into the current state and development of Icinga 2. Subsequently we heard about Icinga Director, in detail the current features and how it works from Markus Frosch. Our third talk about Elastic Stack and how to integrate it with Icinga 2 by Thomas Widhalm rounded off the camp.

Again, this Icinga Camp was a perfect way for customers and users to get to know the team members from NETWAYS. Our speakers were happy to answer many interesting and sophisticated questions as well as to take in ideas and requests from the audience. In the end, everybody attending the camp profited a lot from these discussions.

Out next stop was at Slack Headquarters where we were invited for a rather casual get-together. The people at Slack were mainly interested in Icinga 2, Icinga Web 2 and all the features available now and in the future. Furthermore it was extremely interesting to get an insight into American company culture and to compare it to Germany. All in all, we had a very good time at Slack HQ, met nice people and everybody was able to gather useful information and facts.

Again a big thank you to our hosts, it was a pleasure to be your guests!

Ab September 2016 startete Sie Ihre Ausbildung zur Fachinformatikerin für Systemintegration bei NETWAYS, wo sie vor allem das Arbeiten mit Linux und freier Software reizt. In ihrer Freizeit überschüttet Sie Ihren Hund mit Liebe, kocht viel Gesundes, werkelt im Garten, liest Bücher und zockt auch mal gerne.
