The EveBox Agent

The EveBox Agent is a tool that processes Suricata EVE log files and sends them to an EveBox or Elasticsearch server. The EveBox Server can then store the events in Elasticsearch or SQLite.

With the EveBox Server​

From the command line:

evebox agent --server http://127.0.0.1:5636 \
    /var/log/suricata/eve.json

Or with a configuration file:

server:
  url: http://127.0.0.1:5636
input:
  paths:
    - "/var/log/suricata/eve.json"

With Elasticsearch​

As of EveBox 0.17.0, the Agent is also capable of sending events to Elasticsearch in a Logstash compatibly way. It cannot send events to Elasticsearch using a schema compatible with Filebeat or Filebeat with the Suricata module. So its use is only advised if your Elasticsearch index is dedicated to EveBox, or a mix of EveBox and Logstash event processed sending to the same index.

With Elasticsearch on the command line:

evebox agent --elasticsearch \
    --elasticsearch-url http://elasticsearch:9200 \
	--elasticsearch-index logstash \
	/var/log/suricata/eve.json

Or with a configuration file:

elasticsearch:
  enabled: true
  url: http://elasticsearch:9200
  index: logstash

GeoIP​

The EveBox Agent can optionally add GeoIP information to Suricata events using the GeoIP2 databases from MaxMind1.

It is highly recommended to create an account with MaxMind and use up to date databases. The databases including with most Linux distributions is from 2019.

To enable GeoIP, add --enable-geoip to the EveBox Agent command line.

The GeoIP databases will be looked for in the following locations.

  • /etc/evebox/GeoLite2-City.mmdb
  • /usr/local/share/GeoIP/GeoLite2-City.mmdb
  • /usr/share/GeoIP/GeoLite2-City.mmdb

Rules​

The EveBox Agent can optionally add the Suricata rule to an alert. This can be enabled in the configuration file. Example:

# The event reader can also add the rule to alert events. Do not enable
# if you already have Suricata logging the rule.
rules:
  - /var/lib/suricata/rules/*.rules
  - /usr/share/suricata/rules/*.rules
  - /etc/suricata/rules/*.rules
